rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
UltraSPARC processors defines that in all cases tininess is detected
before rounding therefore rounding up to the smallest normalized number
should set the underflow flag. This change is needed for using SoftFloat
on sparc64 for reference purposes.

This fix mostly matters after r206129 that made it possible for
st_blksize to be greater than 4K. For this reason, this change should
be MFC-ed before r206129.
Also, it seems that all FreeBSD uitlities that use db(3) hash databases
and create new databases in files, specify their own block size value
and thus do not depend on block size autotuning.

- Westmere based CPU (Xeon 5600, Corei7 980X) support.
- New man pages with events list for core and uncore.
- Updated Corei7 events with Intel 253669-033US December 2009 doc.
There is some removed events in the documentation, they have been
kept in the code but documented in the man page as obsolete.
- Offcore response events can be setup with rsp token.

A nice thing about POSIX 2008 is that it finally standardizes a way to
obtain file access/modification/change times in sub-second precision,
namely using struct timespec, which we already have for a very long
time. Unfortunately POSIX uses different names.
This commit adds compatibility macros, so existing code should still
build properly. Also change all source code in the kernel to work
without any of the compatibility macros. This makes it all a less
ambiguous.
I am also renaming st_birthtime to st_birthtim, even though it was a
local extension anyway. It seems Cygwin also has a st_birthtim.
parser. This merge does not change any API and should not break any
native or thirdparty applications.
Changes include:
* Merge multiple report ID support and other improvements from kernel
HID parser.
* Ignore rid argument in hid_start_parser, parse all the report items since
we now support multiple report ID.
* Skip report ID byte in hid_get_data() and set report ID byte in
hid_set_data(), if report ID is non-zero.
* Reimplement hid_get_report_id: instead get report id from uhid device
(which is always 0), try parsing the report descriptor and return the
first report ID encountered.

According to POSIX open() must return ENOTDIR when the path name does
not refer to a path name. Change vn_open() to respect this flag. This
also simplifies the Linuxolator a bit.
Scrt1_c.o was accidentally compiled with -DGCRT (profiling), like gcrt1_c.o.

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.
Erwin ran an exp-run with libcompat and <regexp.h> removed. It turns out
the regexp library is almost entirely unused. In fact, it looks like it
is sometimes used by accident. Because these function names clash with
libc's <regex.h>, some application use both <regex.h> and libcompat,
which means they link against the wrong regex library.
This commit removes the regexp library and reimplements re_comp() and
re_exec() using <regex.h>. It seems the grammar of the regular
expressions accepted by these functions is similar to POSIX EREs.
After this commit, 1 low-profile port will be broken, but the maintainer
already has a patch for it sitting in his mailbox.

- Use word-sized test for unaligned pointer before working
the hard way.
Memory page boundary is always integral multiple of a word
alignment boundary. Therefore, if we can access memory
referenced by pointer p, then (p & ~word mask) must be also
accessible.
- Better utilization of multi-issue processor's ability of
concurrency.
The previous implementation utilized a formular that must be
executed sequentially. However, the ~, & and - operations can
actually be caculated at the same time when the operand were
different and unrelated.
The original Hacker's Delight formular also offered consistent
performance regardless whether the input would contain
characters with their highest-bit set, as it catches real
nul characters only.
These two optimizations has shown further improvements over the
previous implementation on microbenchmarks on i386 and amd64 CPU
including Pentium 4, Core Duo 2 and i7.
