- While SPARC V9 allows tininess to be detected either before or after
rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
UltraSPARC processors defines that in all cases tinyness is detected
before rounding, therefore rounding up to the smallest normalised
number should set the underflow flag.
- If an infinite result is rounded down, the result should have an
exponent 1 less than the value for infinity.

the problems related to the handling of broken DNSSEC trust chains.
This fix is only relevant for those who have DNSSEC validation
enabled and configure trust anchors from third parties, either
manually, or through a system like DLV.
Scrt1_c.o was accidentally compiled with -DGCRT (profiling), like gcrt1_c.o.
This problem is i386-specific, the other architectures are OK.
If you have problems with PIE executables such as samba and cups leaving
behind gmon files, rebuild them after installing this change.

Use thr_once() with once_t controls to initialize various thread_key_t
objects used to provide per-thread storage in the RPC code. Almost all
of these used double-checking with a dedicated mutex (tsd_lock) to do this
before. However, that is not always safe with more relaxed memory orders.
There were also other bugs, such as one in __rpc_createrr() that caused a
new key to be allocated each time __rpc_createrr() was invoked.
- The OPSZ macro actually only does the right thing for int32 and int64
operands but not for double and extended double ones. Instead of trying
to fix the macro just nuke it and unroll the loops in the correct way
though as extended double operands turn out to be the only special case.
- For FxTO{s,d,q} the source operand is int64 so rs2 has to be re-decoded
after setting type accordingly as it's generally decoded using the low
2 bits as the type, which are 0 for these three instructions.
- Similarly, in case of F{s,d,q}TOx the target is int64 so rd has to be
re-decoded using not only the operand mask appropriate for int64 but
also the correct register number encoding.
- Use const where appropriate.
- Wrap long lines.

In _gettemp(), check that the length of the path doesn't exceed
MAXPATHLEN. Otherwise the path name (or part of it) may not fit to
carrybuf causing a buffer overflow.

Make pause(3) implementation not depended on the legacy sigcompat.c
interfaces. Do not block rt signals during and after pause(3) calls.
Use private libc namespace to call proper methods.
framebuffer driver, etc. work on FreeBSD/amd64.
A significant amount of improvements were done by jkim@ during the recent
months to make vesa(4) work better, over the initial code import. This
work is based on OpenBSD's x86emu implementation and contributed by
paradox <ddkprog yahoo com> and swell.k at gmail com.
Hopefully I have stolen all their work to 8-STABLE :)
All bugs in this commit are mine, as usual.
These fixes correct a problem in the file system that treats large
inode numbers as negative rather than unsigned. For a default
(16K block) file system, this bug began to show up at a file system
size above about 16Tb.
These fixes also update newfs to ensure that it will never create a
filesystem with more than 2^32 inodes.
They also update libufs, tunefs, and growfs so that they properly
handle inode numbers as unsigned.

Better glibc compatibility for getline/getdelim:
- Tolerate applications that pass a NULL pointer for the buffer and
claim that the capacity of the buffer is nonzero.
- If an application passes in a non-NULL buffer pointer and claims the
buffer has zero capacity, we should free (well, realloc) it
anyway. It could have been obtained from malloc(0), so failing to
free it would be a small memory leak.
Fix a regression that was introduced in r191882.
I changed login_tty() to only work when the application is not a session
leader yet. This works fine for applications in the base system, but it
turns out various applications call this function after daemonizing,
which means they already use their own session.
If setsid() fails, just call tcsetsid() on the current session.
tcsetsid() will already perform proper security checks.
