73379f0be5 set major version of shlibs to 0
WARNING: this will break existing dynamically linked binaries if they
exist. If you have any:
	. re-build world statically first if necessary
	. remove libraries from /lib and /usr/lib
	. then build world

This change:
	. avoids possible future dismay when interfacing other
	  systems' binaries; done until they are abi-compatible

Thanks to Antoine Leca for pointing this out.

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
	. also import NetBSD ldd

4f78dfcabc libutil: add O_NOCTTY to old pty open code
. fixes e.g. ssh sessions not getting their own
	  controlling tty (causing ^C getting broadcast to too
	  many processes)
	. previously (before -lutil) handled like this by bsd-openpty.c in
	  openssh
	. reported by Andy Kosela, debugged by ThomasV

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

fb50da9dad Fine grained compatibility with _RENAMEd symbols
The NetBSD libc provides a mechanism to have versions of system calls.
By 'renaming' symbols to a new version, freshly compiled programs will
automatically use the new symbol iff they use the proper header files. The
old, not renamed, version of the symbol will still exist (after being moved
to the compat directory), so old programs can still link.

Since MINIX doesn't support dynamic linking, the whole rename mechanism
doesn't really work for us. However, removing it would create a huge diff
with the current NetBSD libc.

A lot of the compat code relies on things we don't (seem to) have, and
therefore does not get built and linked. This causes trouble for tools like
autoconf, which will fail to find the renamed symbols. For example,
currently select gets renamed to __select50 in libc. Autoconf looks for
'select' and doesn't find it and reports we don't have it. This is where
the compat.S stub comes into play: it generates the old symbols and jumps to
the new symbols. However, as this is done in one object file, all renamed
symbols get linked together, causing binaries to be huge. This patch fixes
that by generating an object file for each renamed symbol.

This patch also makes the MISSING_SYSCALLS more complete and marginally
reduces the diff with NetBSD.

a209c3ae12 Fix a ton of compiler warnings
This patch fixes most of current reasons to generate compiler warnings.
The changes consist of:
 - adding missing casts
 - hiding or unhiding function declarations
 - including headers where missing
 - add __UNCONST when assigning a const char * to a char *
 - adding missing return statements
 - changing some types from unsigned to signed, as the code seems to want
   signed ints
 - converting old-style function definitions to current style (i.e.,
   void func(param1, param2) short param1, param2; {...} to
   void func (short param1, short param2) {...})
 - making the compiler silent about signed vs unsigned comparisons. We
   have too many of those in the new libc to fix.

A number of bugs in the test set were fixed. These bugs were never
triggered with our old libc. Consequently, these tests are now forced to
link with the new libc or they will generate errors (in particular tests 43
and 55).

Most changes in NetBSD libc are limited to moving aroudn "#ifndef __minix"
or stuff related to Minix-specific things (code in sys-minix or gen/minix).

0c3983b25a update/fix manpage support
. add bsd-style MLINKS to minix man set, restoring aliases
	  (e.g. man add64 -> int64)
	. update daily cron script to run makewhatis and restore makewhatis
	  in man Makefile (makedb), restores functionality of man -k
	. netbsd imports of man, mdocml, makewhatis, libutil, apropos
	. update man.conf with manpage locations, restoring man [-s] <section>
	. throws out some obsolete manpages

cc17b27a2b Build NetBSD libc library in world in ELF mode.
3 sets of libraries are built now:
  . ack: all libraries that ack can compile (/usr/lib/i386/)
  . clang+elf: all libraries with minix headers (/usr/lib/)
  . clang+elf: all libraries with netbsd headers (/usr/netbsd/)

Once everything can be compiled with netbsd libraries and headers, the
/usr/netbsd hierarchy will be obsolete and its libraries compiled with
netbsd headers will be installed in /usr/lib, and its headers
in /usr/include. (i.e. minix libc and current minix headers set
will be gone.)

To use the NetBSD libc system (libraries + headers) before
it is the default libc, see:
   http://wiki.minix3.org/en/DevelopersGuide/UsingNetBSDCode
This wiki page also documents the maintenance of the patch
files of minix-specific changes to imported NetBSD code.

Changes in this commit:
  . libsys: Add NBSD compilation and create a safe NBSD-based libc.
  . Port rest of libraries (except libddekit) to new header system.
  . Enable compilation of libddekit with new headers.
  . Enable kernel compilation with new headers.
  . Enable drivers compilation with new headers.
  . Port legacy commands to new headers and libc.
  . Port servers to new headers.
  . Add <sys/sigcontext.h> in compat library.
  . Remove dependency file in tree.
  . Enable compilation of common/lib/libc/atomic in libsys
  . Do not generate RCSID strings in libc.
  . Temporarily disable zoneinfo as they are incompatible with NetBSD format
  . obj-nbsd for .gitignore
  . Procfs: use only integer arithmetic. (Antoine Leca)
  . Increase ramdisk size to create NBSD-based images.
  . Remove INCSYMLINKS handling hack.
  . Add nbsd_include/sys/exec_elf.h
  . Enable ELF compilation with NBSD libc.
  . Add 'make nbsdsrc' in tools to download reference NetBSD sources.
  . Automate minix-port.patch creation.
  . Avoid using fstavfs() as it is *extremely* slow and unneeded.
  . Set err() as PRIVATE to avoid name clash with libc.
  . [NBSD] servers/vm: remove compilation warnings.
  . u32 is not a long in NBSD headers.
  . UPDATING info on netbsd hierarchy
  . commands fixes for netbsd libc
