69eead77ff New image framework generation
The CD now boots directly from the ISO 9660 filesystem instead of using
MBR partitioning with Minix file systems. This saves some space on the
CD and reduces memory requirements by some unknown amount as the root
ramdisk is completely eliminated.

The x86 hard drive image creation is also rewritten in the same
fashion.

The setup is modified to be more NetBSD-like (unpacking sets
tarballs instead of blindly copying the CD contents). Splitting MINIX
into sets is done in another commit due to it being a nightmare to
rebase.

Since MINIX lacks union mounts for now, a bunch of ramdisks are
generated at run-time to make parts of the filesystem writeable for the
CD. This solution isn't ideal, but it's enough for an installation CD.

b65ad59e08 libminixfs: add support for 64-bit block numbers
There are currently no devices out there that require this change.
The change is merely needed to support subsequent changes.

3814aed560 libsa: add string precision support to vprintf
We already had a hack to ignore the precision, but the ACPI driver
requires an actual implementation--it prints garbage at the end of
some strings otherwise.  This patch adds support for precision for
strings only, limiting printing to the given number of characters.
For all other specifiers, precision is still unsupported.

3b0299dd65 bootloader: pass memory map to kernel
Previously, the bootloader would only provide a single memory range.
At least on VirtualBox, this memory range includes the ACPI tables,
which the kernel then happily overwrites when executing VM.  Much of
the infrastructure to use a fullblown memory map is already in place;
this patch adds the last (and strangely missing) bit of generating
the memory map in a multiboot-compatible way.

It should be noted that both the bootloader and the kernel actually
violate the multiboot specification by not packing the structure for
the memory ranges.  This is a NetBSD bug, but it is also a nonissue
for (our) practical purposes.  It can be fixed without changing the
code added in this patch.

5ae1a533c7 ARM: can build with llvm, switch to EABI

	. minor build fixes
	. allow  build with llvm without crossbuilding llvm itself
	. can now build minix/arm using llvm and eabi - without C++
	  support for now (hence crossbuilding llvm itself is turned off
	  for minix/arm)

b029fb598a new libunwind, updated to netbsd b1f513eedd
existing libunwind used '0' in lsda_encoding as 'not present,'
whereas that is a valid encoding and does occur and would be
ignored. a missing encoding is actually 0xff.

The commit that addresses this is:

    0 is a valid LSDA encoding and can be seen in statically linked
    programs. Initialize lsdaEncoding to DW_EH_PE_omit and check for that
    value to decide whether a value should be decoded.

more bugfixes are necessary. this update is up to:

78cfc9712b Prefix libc (u)mount with minix_
The goal is to prevent a name collision with the expected mount/umount
function signatures, if we decide one day to allow any application
using those to work on MINIX.

At this moment the caller has to start the required services, but if we
implement that logic inside the mount/unmout function, this would allow
any application to call those function successfully.

By renaming those now, we prevent a possible ABI break in the future.

193733f9e2 Hide SO_PASSCRED and SO_PEERCRED by default.
This cause in some software to assume we are linux, as this is rightly
only used there.

By default hide it behind _MINIX_SYSTEM, until we have removed traces
of it from getpeereid/[gs]etsocketopt and replaced it by the NetBSD
mechanism.

0b79eac642 mmap: accept non-PROT_WRITE MAP_SHARED mappings
Currently we don't accept writable file mmap()s, as there is no
system in place to guarantee dirty buffers would make it back to
disk. But we can actually accept MAP_SHARED for PROT_READ mappings,
meaning the ranges aren't writable at all (and no private copy is
made as with MAP_PRIVATE), as it turns out a fairly large class of
usage.

	. fail writable MAP_SHARED mappings at runtime
	. reduces some minix-specific patches
	. lets binutils gold build on minix without further patching

58b8ff5ffa VFS: add F_FLUSH_FS_CACHE fcntl
This fcntl requests all cached blocks associated with the minor device
number associated with the regular file are invalidated. If the file
is a block special, invalidate the blocks associated with that minor
device instead.

This is to be used for a test that tests unmapped file-mapped memory
ranges whose blocks are not in the cache and therefore must be fetched
from a FS.
