1470d46611 Fix long (and long long) to long double, unsigned to long double and unsigned
long (and unsigned long long) to long double conversions.
- Add a parameter that specifies the position of the sign bit to the _QP_TTOQ
  macro, previously it always looked at bit 31.  Pass a negative number to
  disable sign inspection for unsigned types.  This fixes _Qp_xtoq(),
  _Qp_uitoq() and _Qp_uxtoq().
- In the functions __fpu_itof() and __fpu_xtof(), look at the sign bit to
  decide whether we're doing a conversion from an unsigned type.  If so, don't
  negate the mantissa if the integer exceeds the biggest signed number.

b33c1067f8 Start to address the race issue between restoring a file's contents
and restoring the metadata.  In particular, the metadata-restore
functions now all accept a file descriptor and a pathname.  If the
file descriptor is set and the platform supports the appropriate
syscall, restore the metadata through the file descriptor.  Otherwise,
restore it through the pathname.  This is complicated by varying
syscall support (FreeBSD has an fchmod(2) but no fchflags(2), for
example) and because non-file entries don't have an fd to use in
restoring attributes (for example, mknod(2) doesn't return a file
handle).

d9d99c5478 Fix libstand on amd64. Rev 1.46 (obrien) removed the -I. that the
bzip2 support provided, and amd64 depended on.  Amd64 has a custom
${.OBJDIR}/machine symlink in it and the -I. picked this up.  Without
it, the libstand code was being compiled in 32 bit mode, but with 64 bit
machine headers.

6f21c8127a Align the stack to a 16 byte boundary so that we can safely call functions
that use SSE. The compiler does attempt to do this in main() but not very
successfully - it still manages to use unaligned offsets from %ebp in some
cases. Also we need to have an aligned stack in case something uses SSE
via _init().

036ae3dd79 - The ai_addrlen of a struct addrinfo used to be a size_t, per
RFC 2553.  In XNS5.2, and subsequently in POSIX-2001 and RFC
  3493, it was changed to a socklen_t.  And, the n_net of a
  struct netent used to be an unsigned long integer.  In XNS5,
  and subsequently in POSIX-2001, it was changed to an uint32_t.
  To accomodate for this while preserving ABI compatibility with
  the old interface, we need to prepend or append 32 bits of
  padding, depending on the (LP64) architecture's endianness.
- Correct 1st argument of getnetbyaddr() to uint32_t on 32
  bit arch.  Stay as is on 64 bit arch for ABI backward
  compatibility for now.

8dcb56dc78 Provide more POSIX-complaint ttyname_r(3) interface[1], which is slightly
different from what has been offered in libc_r (the one spotted in the
original PR which is found in libthr has already been removed by David's
commit, which is rev. 1.44 of lib/libthr/thread/thr_private.h):
	- Use POSIX standard prototype for ttyname_r, which is,
		int ttyname_r(int, char *, size_t);
	  Instead of:
	  	char *ttyname_r(int, char *, size_t);
	  This is to conform IEEE Std 1003.1, 2004 Edition [1].
	- Since we need to use standard errno for return code, include
	  errno.h in ttyname.c
	- Update ttyname(3) implementation according to reflect the API
	  change.
	- Document new ttyname_r(3) behavior
	- Since we already make use of a thread local storage for
	  ttyname(3), remove the BUGS section.
	- Remove conflicting ttyname_r related declarations found in libc_r.

Hopefully this change should not have changed the API/ABI, as the ttyname_r
symbol was never introduced before the last unistd.h change which happens a
couple of days before.

42307a8f43 Since the FreeBSD local modifications are mostly trivial (consisting
primarily of pointless $FreeBSD$ tags), sync most files in HEAD with
those in the ZLIB branch.  This minimizes the differences between
HEAD and ZLIB and should simplify future imports.

After this, there are only three files with local modifications
(gzio.c, minigzip.c, and zconf.h) and two non-vendor files
(Makefile, zopen.c).  The rest exactly match the vendor distribution.

c5153e190b Add convenience APIs pmc_width() and pmc_capabilities() to -lpmc.
Have pmcstat(8) and pmccontrol(8) use these APIs.

Return PMC class-related constants (PMC widths and capabilities)
with the OP GETCPUINFO call leaving OP PMCINFO to return only the
dynamic information associated with a PMC (i.e., whether enabled,
owner pid, reload count etc.).

Allow pmc_read() (i.e., OPS PMCRW) on active self-attached PMCs to
get upto-date values from hardware since we can guarantee that the
hardware is running the correct PMC at the time of the call.

Bug fixes:
 - (x86 class processors) Fix a bug that prevented an RDPMC
   instruction from being recognized as permitted till after the
   attached process had context switched out and back in again after
   a pmc_start() call.

   Tighten the rules for using RDPMC class instructions: a GETMSR
   OP is now allowed only after an OP ATTACH has been done by the
   PMC's owner to itself.  OP GETMSR is not allowed for PMCs that
   track descendants, for PMCs attached to processes other than
   their owner processes.

 - (P4/HTT processors only) Fix a bug that caused the MI and MD
   layers to get out of sync.  Add a new MD operation 'get_config()'
   as part of this fix.

 - Allow multiple system-mode PMCs at the same row-index but on
   different CPUs to be allocated.

 - Reject allocation of an administratively disabled PMC.

256543d9b1 Certain filenames between 245 and 255 characters long would cause an
internal error if pax extended attributes were being generated.  Being
< 255 characters, the first-pass path editing (to generate a
ustar-compatible name for the main entry) wouldn't occur, and the
second-pass path editing (to generate a ustar name for the pax
attributes entry) assumed the input was already < 245 chars.

The core problem here was using an abbreviated algorithm for the
second pass that relied on the first pass having already run.  The
rewritten code is much simpler: It just uses the full path-shortening
algorithm for building both ustar pathnames.  This way, the second
ustar pathname will always be short enough.

a8bc22b47a natd core dumps when -reverse switch is used because of a bug in
libalias.

In /usr/src/lib/libalias/alias.c, the functions LibAliasIn and
LibAliasOutTry call the legacy PacketAliasIn/PacketAliasOut instead
of LibAliasIn/LibAliasOut when the PKT_ALIAS_REVERSE option is set.
In this case, the context variable "la" gets lost because the legacy
compatibility routines expect "la" to be global.  This was obviously
an oversight when rewriting the PacketAlias* functions to the
LibAlias* functions.

The fix (as shown in the patch below) is to remove the legacy
subroutine calls and replace with the new ones using the "la" struct
as the first arg.

 4. thread synchronization is fully based on umtx, mainly, condition
    variable and other synchronization objects were rewritten by using
    umtx directly. those objects can be shared between processes via
    shared memory, it has to change ABI which does not happen yet.
 5. default stack size is increased to 1M on 32 bits platform, 2M for

As the result, some mysql super-smack benchmarks show performance is

  sizeof(fenv_t).  I stuck the saved mxcsr in some discontiguous
  reserved bits in the existing structure.

- Attempting to access the mxcsr on older processors results
  in an illegal instruction exception, so support for SSE must
  be detected at runtime.  (The extra baggage is optimized away
  if either the application or libm is compiled with -msse{,2}.)

I didn't run tests to ensure that this doesn't SIGILL on older 486's
lacking the cpuid instruction or on other processors lacking SSE.
Results from running the fenv regression test on these processors
would be appreciated.  (You'll need to compile the test with
-DNO_STRICT_DFL_ENV.)  If you have an 80386, or if your processor
supports SSE but the kernel didn't enable it, then you're probably out
of luck.

Also, I un-inlined some of the functions that grew larger as a result
of this change, moving them from fenv.h to fenv.c.

10b01832c3 Replace fegetmask() and fesetmask() with feenableexcept(),
fedisableexcept(), and fegetexcept().  These two sets of routines
provide the same functionality.  I implemented the former as an
undocumented internal interface to make the regression test easier to
write.  However, fe(enable|disable|get)except() is already part of
glibc, and I would like to avoid gratuitous differences.  The only
major flaw in the glibc API is that there's no good way to report
errors on processors that don't support all the unmasked exceptions.

7b74e4a759 Remove fpsetsticky(). This was added for SysV compatibility, but due
to mistakes from day 1, it has always had semantics inconsistent with
SVR4 and its successors.  In particular, given argument M:

- On Solaris and FreeBSD/{alpha,sparc64}, it clobbers the old flags
  and *sets* the new flag word to M.  (NetBSD, too?)
- On FreeBSD/{amd64,i386}, it *clears* the flags that are specified in M
  and leaves the remaining flags unchanged (modulo a small bug on amd64.)
- On FreeBSD/ia64, it is not implemented.

There is no way to fix fpsetsticky() to DTRT for both old FreeBSD apps
and apps ported from other operating systems, so the best approach
seems to be to kill the function and fix any apps that break.  I
couldn't find any ports that use it, and any such ports would already
be broken on FreeBSD/ia64 and Linux anyway.

By the way, the routine has always been undocumented in FreeBSD,
except for an MLINK to a manpage that doesn't describe it.  This
manpage has stated since 5.3-RELEASE that the functions it describes
are deprecated, so that must mean that functions that it is *supposed*
to describe but doesn't are even *more* deprecated.  ;-)

Note that fpresetsticky() has been retained on FreeBSD/i386.  As far
as I can tell, no other operating systems or ports of FreeBSD
implement it, so there's nothing for it to be inconsistent with.

  nexttowardl is an alias for nextafterl.
- Add fmal.
- Add man pages for new routines: fmal, nextafterl,
  nexttoward{,f,l}, scalb{,l}nl.

Note that on platforms where long double is the same as double, we
generally just alias the double versions of the routines, since doing
so avoids extra work on the source code level and redundant code in
the binary.  In particular:

		ldbl53		ldbl64/113
fmal       	s_fma.c		s_fmal.c
ldexpl     	s_scalbn.c	s_scalbnl.c
