Instead, filter it in libc for old networking implementations, as
those do not support sending SIGPIPE to user processes anyway. This
change allows newer socket drivers to implement the flag as per the
specification.

We do not support any PF functionality, nor do we intend to. However,
some NetBSD utilities rely on the presence of these files. Not all of
the files are installed. The NetBSD source seems rather inconsistent
in where from to include these files. We simply follow what NetBSD
does, though.

While still a small subset of the NetBSD headers, this set should
allow various additional utilities to be compiled without too many
MINIX3-specific changes (even if those utilities will not yet work).

Some functions in lib/libc/net were disabled on MINIX3 only, but with
a few added header files they build just fine, even though some of
them rely on system functionality that has not yet been implemented.
Since the functionality is unlikely to be used in practice (because
it typically requires the use of protocol families that themselves are
not yet supported, such as IPv6), already enabling it right now helps
in building packages that rely on the functionality being present at
compile time, while not posing any practical risk of breaking the same
packages at run time.

The NetBSD bootloader attempts to load NetBSD kernel modules for
"unusual" file systems. We do not support NetBSD kernel modules,
and thus, the bootloader gives us warnings about not being able
to load them, in particular when booting CD images. This patch
disables the NetBSD file system module autoload feature.

- switch to the NetBSD identifier system; it is not only better, but
also required for porting NetBSD ipcs(1) and ipcrm(1); however, it
requires that slots not be moved, and that results in some changes;
- synchronize some other things with NetBSD: where keys are kept, as
well as various non-permission mode flags;
- fix semctl(2) vararg retrieval and message field type;
- use SUSPEND instead of weird reply exceptions in the call table;
- fix several memory leaks and at least one missing permission check;
- improve the atomicity of semop(2) by a small amount, even though
its atomicity is still broken at a fundamental level;
- use the new cheaper way to retrieve the current time;
- resolve all level-5 LLVM warnings.

Now that uname(3) uses sysctl(2), we no longer need sysuname(2).
Backward compatibility is retained for old statically linked
binaries for a short while.
Also remove the now-obsolete MINIX3-specific "arch" field from the
utsname structure. While this is an ABI break at the libc level,
it should pose no problems in practice, because:
- statically linked programs (i.e., all of the base system) are not
affected, as they will use headers synchronized with libc;
- the structure is getting smaller, thus, older dynamically linked
programs (typically in pkgsrc) using the new libc will end up with
garbage in the "arch" field, but it is unlikely they will use this
field anyway, since it was specific to MINIX3;
- new dynamically linked programs using an old libc could end up with
memory corruption, but this is not a scenario that is expected to
occur in the first place - certainly not with programs from pkgsrc.

The new MIB service implements the sysctl(2) system call which, as
we adopt more NetBSD code, is an increasingly important part of the
operating system API. The system call is implemented in the new
service rather than as part of an existing service, because it will
eventually call into many other services in order to gather data,
similar to ProcFS. Since the sysctl(2) functionality is used even
by init(8), the MIB service is added to the boot image.
MIB stands for Management Information Base, and the MIB service
should be seen as a knowledge base of management information.
The MIB service implementation of the sysctl(2) interface is fairly
complete; it incorporates support for both static and dynamic nodes
and imitates many NetBSD-specific quirks expected by userland. The
patch also adds trace(1) support for the new system call, and adds
a new test, test87, which tests the fundamental operation of the
MIB service rather thoroughly.

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.

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.

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.

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.

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.

Lazy VFP processing works a lot better if the functions contain a return
instruction.
replace invocations of -Ttext=.. with --section-start=.text=.. for
gnu gold-ld. it was giving very weird results when given page-rounded
values. --section-start=.text=.. works for both bfd-ld and gold.
-Add support for returning the amount of characters that would have been
written if the buffer was large enough.
-Protect code against NULL dereference.

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.

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

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.
