a0a1440a52 remove utimes() workarounds
With the addition of utimes(), we can remove the workarounds
and use the original NetBSD code for timestamping files.

Also restore use of -p & -r for install while building

fbd82e76a4 Let the build system manage compilation flags
Do not hardcode warning and optimisation flags, otherwise the
main options (i.e. DBG, CPPFLAGS) will not work as expected.

You can still provide specific default by using DBG?=<value>.

Doing so leaves the opportunity to override the setting from the
commandline, while the default value from the build system is
then ignored for that particular package.

When crosscompiling, and using build.sh, adding -V DBG=<value> has
this same effect as make DBG=<value>.

8f3fbf7cc1 Cleanup: Remove minix.bootprog.mk
The build system distinction between "bootprog" and "service" is
meaningless as boot programs are standard services.

As minix.service.mk simply imports minix.bootprog.mk, reduce confusion
by removing minix.bootprog.mk and placing the rules in minix.service.mk.

b8a678ef1d Cross compile on minix support
* Remade patch so it works with minix patch tool.

 * New MINIX tar support -ox, so revert back to it

   In fetch scripts, tar had been replaced by bsdtar as the prebvious
   tar did not support the -o flag under minix, which is required to
   prevent usage of tar file stored user and group information.

   This introduces portability problems. As our new tar tool now
   support that flag revert back to improve portability.

9152e1c5a7 Upgrading build system to new NetBSD revision
The tested targets are the followgin ones:
 * tools
 * distribution
 * sets
 * release

The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.

For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.

Regarding new or modifications of Makefiles a few things:
 * Read share/mk/bsd.README
 * If you add a subdirectory, add a Makefile in it, and have it called
   by the parent through the SUBDIR variable.
 * Do not add arbitrary inclusion which crosses to another branch of
   the hierarchy; If you can't do without it, put a comment on why.
   If possible, do not use inclusion at all.
 * Use as much as possible the infrastructure, it is here to make
   life easier, do not fight it.

Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"

e415d48872 Libc update to simplify merge.
Bumping libc files for unsupported architectures, to simplify merging.
A bunch of small fixes:
 * in libutil update
 * the macro in endian.h
 * some undefined types due to clear separation from host.
 * Fix a warning for cdbr.c

Some modification which were required for the new build system:
 * inclusion path for const.h in sconst, still hacky
 * Removed default malloc.c which conflicts on some occasions.

50e2064049 No more intel/minix segments.
This commit removes all traces of Minix segments (the text/data/stack
memory map abstraction in the kernel) and significance of Intel segments
(hardware segments like CS, DS that add offsets to all addressing before
page table translation). This ultimately simplifies the memory layout
and addressing and makes the same layout possible on non-Intel
architectures.

There are only two types of addresses in the world now: virtual
and physical; even the kernel and processes have the same virtual
address space. Kernel and user processes can be distinguished at a
glance as processes won't use 0xF0000000 and above.

No static pre-allocated memory sizes exist any more.

Changes to booting:
        . The pre_init.c leaves the kernel and modules exactly as
          they were left by the bootloader in physical memory
        . The kernel starts running using physical addressing,
          loaded at a fixed location given in its linker script by the
          bootloader.  All code and data in this phase are linked to
          this fixed low location.
        . It makes a bootstrap pagetable to map itself to a
          fixed high location (also in linker script) and jumps to
          the high address. All code and data then use this high addressing.
        . All code/data symbols linked at the low addresses is prefixed by
          an objcopy step with __k_unpaged_*, so that that code cannot
          reference highly-linked symbols (which aren't valid yet) or vice
          versa (symbols that aren't valid any more).
        . The two addressing modes are separated in the linker script by
          collecting the unpaged_*.o objects and linking them with low
          addresses, and linking the rest high. Some objects are linked
          twice, once low and once high.
        . The bootstrap phase passes a lot of information (e.g. free memory
          list, physical location of the modules, etc.) using the kinfo
          struct.
        . After this bootstrap the low-linked part is freed.
        . The kernel maps in VM into the bootstrap page table so that VM can
          begin executing. Its first job is to make page tables for all other
          boot processes. So VM runs before RS, and RS gets a fully dynamic,
          VM-managed address space. VM gets its privilege info from RS as usual
          but that happens after RS starts running.
        . Both the kernel loading VM and VM organizing boot processes happen
	  using the libexec logic. This removes the last reason for VM to
	  still know much about exec() and vm/exec.c is gone.

Further Implementation:
        . All segments are based at 0 and have a 4 GB limit.
        . The kernel is mapped in at the top of the virtual address
          space so as not to constrain the user processes.
        . Processes do not use segments from the LDT at all; there are
          no segments in the LDT any more, so no LLDT is needed.
        . The Minix segments T/D/S are gone and so none of the
          user-space or in-kernel copy functions use them. The copy
          functions use a process endpoint of NONE to realize it's
          a physical address, virtual otherwise.
        . The umap call only makes sense to translate a virtual address
          to a physical address now.
        . Segments-related calls like newmap and alloc_segments are gone.
        . All segments-related translation in VM is gone (vir2map etc).
        . Initialization in VM is simpler as no moving around is necessary.
        . VM and all other boot processes can be linked wherever they wish
          and will be mapped in at the right location by the kernel and VM
          respectively.

Other changes:
        . The multiboot code is less special: it does not use mb_print
          for its diagnostics any more but uses printf() as normal, saving
          the output into the diagnostics buffer, only printing to the
          screen using the direct print functions if a panic() occurs.
        . The multiboot code uses the flexible 'free memory map list'
          style to receive the list of free memory if available.
        . The kernel determines the memory layout of the processes to
          a degree: it tells VM where the kernel starts and ends and
          where the kernel wants the top of the process to be. VM then
          uses this entire range, i.e. the stack is right at the top,
          and mmap()ped bits of memory are placed below that downwards,
          and the break grows upwards.

Other Consequences:
        . Every process gets its own page table as address spaces
          can't be separated any more by segments.
        . As all segments are 0-based, there is no distinction between
          virtual and linear addresses, nor between userspace and
          kernel addresses.
        . Less work is done when context switching, leading to a net
          performance increase. (8% faster on my machine for 'make servers'.)
	. The layout and configuration of the GDT makes sysenter and syscall
	  possible.

4b999f1962 build shared versions of libraries
building defaults to off until clang is updated.

current clang does not handle -shared, necessary to change the ld
invocation to build shared libraries properly. a new clang should be
installed and MKPIC defaults to no unless the newer clang is detected.

changes:

	. mainly small imports of a Makefile or two and small fixes
	  (turning things back on that were turned off in Makefiles)
	. e.g.: dynamic librefuse now depends on dynamic
	  libpuffs, so libpuffs has to be built dynamically too
	  and a make dependency barrier is needed in lib/Makefile
	. all library objects now have a PIC (for .so) and non-PIC
	  version, so everything is built twice.
	. generate PIC versions of the compat (un-RENAMEd) jump files,
	  include function type annotation in generated assembly
	. build progs with -static by default for now
	. also build ld.elf_so

a5190194a0 build: don't -L/usr/pkg/lib
You might have to update the compiler-rt package! See UPDATING.

	. the purpose of this -L was solely to find compiler-rt, which contains
	  runtime support code for clang-compiled binaries
	. this also makes all other packaged libraries visible, however
	. it is cleaner to isolate the base system from packages, and so
	  compiler-rt puts itself in /usr/pkg/compiler-rt/lib/ too, which the
	  base system henceforth uses exclusively
	. e.g. this solves a link failure when libfetch is installed as a
	  package
	. the new compiler-rt package also puts itself in /usr/pkg/lib for 'old'
	  systems; that is harmless. The benefit of 'new' systems is that the other
	  packages are hidden.

2fe8fb192f Full switch to clang/ELF. Drop ack. Simplify.
There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.

Changes in this commit:

	. drop boot monitor -> allowing dropping ack support
	. facility to copy ELF boot files to /boot so that old boot monitor
	  can still boot fairly easily, see UPDATING
	. no more ack-format libraries -> single-case libraries
	. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
	. drop several ack toolchain commands, but not all support
	  commands (e.g. aal is gone but acksize is not yet).
	. a few libc files moved to netbsd libc dir
	. new /bin/date as minix date used code in libc/
	. test compile fix
	. harmonize includes
	. /usr/lib is no longer special: without ack, /usr/lib plays no
	  kind of special bootstrapping role any more and bootstrapping
	  is done exclusively through packages, so releases depend even
	  less on the state of the machine making them now.
	. rename nbsd_lib* to lib*
	. reduce mtree

b4d909d415 Split block/character protocols and libdriver
This patch separates the character and block driver communication
protocols. The old character protocol remains the same, but a new
block protocol is introduced. The libdriver library is replaced by
two new libraries: libchardriver and libblockdriver. Their exposed
API, and drivers that use them, have been updated accordingly.
Together, libbdev and libblockdriver now completely abstract away
the message format used by the block protocol. As the memory driver
is both a character and a block device driver, it now implements its
own message loop.

The most important semantic change made to the block protocol is that
it is no longer possible to return both partial results and an error
for a single transfer. This simplifies the interaction between the
caller and the driver, as the I/O vector no longer needs to be copied
back. Also, drivers are now no longer supposed to decide based on the
layout of the I/O vector when a transfer should be cut short. Put
simply, transfers are now supposed to either succeed completely, or
result in an error.

After this patch, the state of the various pieces is as follows:
- block protocol: stable
- libbdev API: stable for synchronous communication
- libblockdriver API: needs slight revision (the drvlib/partition API
  in particular; the threading API will also change shortly)
- character protocol: needs cleanup
- libchardriver API: needs cleanup accordingly
- driver restarts: largely unsupported until endpoint changes are
  reintroduced

As a side effect, this patch eliminates several bugs, hacks, and gcc
-Wall and -W warnings all over the place. It probably introduces a
few new ones, too.

Update warning: this patch changes the protocol between MFS and disk
drivers, so in order to use old/new images, the MFS from the ramdisk
must be used to mount all file systems.
