- Add missing stuff from Issue 6 (some of it commented out)
- Fix _POSIX_THREAD -> PTHREAD variable confusion
- Amend PTHREAD_KEYS_MAX to 256 since this is what libpthread defined internally
(I found no instances where three arguments were actually
used, as per the claim in the comment. If there are any
in third party code then they will need to use a cast)

This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.
unimplemented, except enough of linkat(2) to hardlink to a symlink.
Everything new in headers is guarded #ifdef _INCOMPLETE_XOPEN_C063 since
some software (e.g.: xcvs in our own tree) will assume they can use openat(2)
when AT_FDCWD is defined. _INCOMPLETE_XOPEN_C063 will go away once support
will be completed.

Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and

2. unfortunately hppa's MB_LEN_MAX is defined incorrectly 6 instead of 32

4. bump libc minor version.
having a system definition for alloca is counter productive as it seems
fairly common to use
#ifdef __GNUC__
#define alloca ..

So, defang this definition as we don't otherwise provide alloca on NetBSD
2. do not use _CTYPE_NUM_CHARS macro to read data from LC_CTYPE(old BSDCTYPE style) database.

3. remove _NB_CACHED_RUNE macro, use _CTYPE_CACHE_SIZE instead.
They implement a space efficent write-once database with fast access

database file decreases from 2.1MB disk space to 307KB. Access

order of magnitude faster otherwise. services_mkdb defaults to the new

2. don't typedef void * wc{type,trans}_t, suggested by soda@-san.

Also replace some includes of <a.out.h> with <nlist.h>, to fix build

The algorithm used is the Jenkins hash. The name (mi_vector_hash)

Add glue for libc ATF tests and include a test case to make sure that
(mis)alignment and endianess are handled correctly.
Bump libc minor to 169.
There was no room to allocate 16 bytes for _rnd in the struct in the _LP64
case, so we dynamically allocate now. Also put the _rnd field last, so that
we are bitwise compatible too. Now of course we've run out of space, so
next time will need to perform more evil tricks to fit.

This avoids 64-bit arithmetics and 64-bit printf formats in parts
of the kernel where it is not really useful, and helps clarity.

[libc]
- localeio.[ch] and lc*.[ch] in src/lib/libc/locale was replaced by
new locale-db implementation using citrus_db backend,
see src/lib/libc/citrus/citrus_lc_*.[ch].
- add citrus_bcs_strtou?l.c. don't use strtou?l locale implementation
internally, because they're locale-aware function.
- add some stubs for multi-locale issue, see {current,global}_locale.c.
- remove some obsolete file, setrunelocale.c, ___runetype_mb.c.
- remove __savectype() from ctypeio.[ch].
[tools]
- mklocale(1): add new option ``-t'' that generates new style
LC_{MONETARY,NUMERIC,TIME,MESSAGES} locale-db format.
- chrtbl(1): added ctypeio.[ch] for __savectype().
[locale-db]
- added en_US.US-ASCII locale.
- removed some shareable locale definition file:
en_US.US-ASCII -> en_US.ISO8859-1, en_US.UTF-8
zh_CN.eucCN -> zh_CN.GB18030
and more...see src/share/locale/*/Makefile.
- remove obsoleted locale sr_YU, added new locale sr_ME, sr_RS.
- change locale name ja_JP.ISO2022-JP* -> ja_JP.ISO-2022-JP*
for X11's locale.alias file alignments.
- fix regression test, wrong wcs?width(3), NAN/INF usage.
i tested release-build following arch:
i386, amd64, hpc{mips,arm,sh}, sparc64, vax.
citrus_lc_*.[ch] also can read old-plain-text style locale-db.

new citrus_db'ed locale-db and localeio.c never check sanity,
so forward compatibility is broken ;-<
old mklocale(1) doesn't know -t option, so you have to rebuild toolchain.

Add Wasabi System's WAPBL (Write Ahead Physical Block Logging)

Greg Oster and Simon Burge.
OK'd by core@, releng@.
EMFILE. We treat _file as an unsigned short to double our range, with a
special case for -1 (closed). Make a note of what we should do about stdio
if we ever bump libc. We could change _file in the future compatibly to an
int by putting it in the extension space but for now we don't bother.
Adjust errno.h in a compatible fashion to avoid -Wredundant-decls issues.
I have run a build to check the tree for places where errno.h is missing,
and fixed the cases I found, but there might be more in MD code.
This function allows the caller finer control of how the writes happen
and doesn't force stdio as interface. Optimise clear_gap a bit to not
fill the gap byte-wise. Bump minor version of libkvm.
Can be used by applications that have their own SIGINT (et al)
handlers and want to exit in a manner that correctly
signals to the parent that the process was terminated by a signal.

Most complex function implementations are from the "c9x-complex" library,

redistributed with the NetBSD license by permission of the author.
Error behaviour and other boundary conditions (branch cuts)
need to be looked at.
For namespace sanity, I've done the rename/weak alias procedure to
most of the exported functions which are also used internally.
Didn't do so for sin/cos(f) yet because assembler implementations use
them directly, and renaming functions shared between the main libm
and the machine specific "overlay" might raise binary compatibility
issues.
it possible to get the pid, euid and egid of the process at the remote

Add a new libc function, getpeereid() to easily get at the euid and egid.
As a consequence, bump libc's minor number.
Document the LOCAL_PEEREID socket option in unix(4).
Based on contribution by Arne H. Juul, minor modifications by myself.
hint pointer, but do so in a way that remains compatible with older
pthread libraries. This can be used to wake another thread before the
calling thread goes asleep, saving at least one syscall + involuntary
context switch. This turns out to be a fairly large win on the condvar
benchmarks that I have tried.
include path: the normal header files now include the "SSP" ones (which one
should note are not really named right: SSP and FORTIFY_SOURCE are independent
features).
Disable USE_SSP on targets where the compiler doesn't support it at all
(mips, alpha) or it's known broken (sh3). But enable FORTIFY_SOURCE,
without SSP, on those platforms -- tested on mipsel.
(what other systems keep in libssp, we already have in libc) into libc
to match what other systems with FORTIFY_SOURCE do. Goodbye, libssp
dependency in libraries and executables. Discussed with christos and
mrg; Christos will merge the headers to get us the rest of the way to a
FORTIFY_SOURCE implementation that works as others' code expects.
- Add POSIX defined system variables and constants of AIO_LISTIO_MAX and
AIO_MAX values. Both with _POSIX_ASYNCHRONOUS_IO, provide them in
sysconf(3) and getconf(1) interfaces.
- Clean up sysconf(3) for handling sysctl nodes dynamically.
Seems to be quite stable. Some work still left to do.
Please note, that syscalls are not yet MP-safe, because
of the file and vnode subsystems.

Probably the check can be removed, I doubt anyone will try to use gcc1
anymore.

From the redhat web page:
http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/gcc/offsetof.html
__offsetof__ (expression)
is equivalent to the parenthesized expression, except that the
expression is considered an integral constant expression even if
it contains certain operators that are not normally permitted in
an integral constant expression. Users should never use __offsetof__
directly; the only valid use of __offsetof__ is to implement the
offsetof macro in <stddef.h>.
g++-3 does not have a built-in offsetof(), but we cannot use the c version,
otherwise we break with -Wold-style-cast.
Inspired by the DF version, but a bit different.
