9980697a44 libarchive is mixing libmd and libcrypto -- correct to use one or the other.
[mixing the two can be quite bad -- they define the same context structures,
 but with differing structure members (and sizes)]

Update the hash function support comments, and update config_freebsd.h
to match.

c273267e83 Improve the accuracy from a max ULP of ~2000 to max ULP < 0.79
on i386-class hardware for sinl and cosl.  The hand-rolled argument
reduction have been replaced by e_rem_pio2l() implementations.  To
preserve history the following commands have been executed:

svn cp src/e_rem_pio2.c ld80/e_rem_pio2l.h
mv ${HOME}/bde/ld80/e_rem_pio2l.c ld80/e_rem_pio2l.h

svn cp src/e_rem_pio2.c ld128/e_rem_pio2l.h
mv ${HOME}/bde/ld128/e_rem_pio2l.c ld128/e_rem_pio2l.h

The ld80 version has been tested by bde, das, and kargl over the
last few years (bde, das) and few months (kargl).  An older ld128
version was tested by das.  The committed version has only been
compiled tested via 'make universe'.

aad93b043a r179417 introduced a bug into pthread_once(). Previously pthread_once()
used a global pthread_mutex_t for synchronization.  r179417 replaced that
with an implementation that directly used atomic instructions and thr_*
syscalls to synchronize callers to pthread_once.  However, calling
pthread_mutex_lock on the global mutex implicitly ensured that
_thr_check_init() had been called but with r179417 this was no longer
guaranteed.  This meant that if you were unlucky enough to have your first
call into libthr be a call to pthread_once(), you would segfault when
trying to access the pointer returned by _get_curthread().

The fix is to explicitly call _thr_check_init() from pthread_once().

d91f88f7f3 Add the posix_fallocate(2) syscall. The default implementation in
vop_stdallocate() is filesystem agnostic and will run as slow as a
read/write loop in userspace; however, it serves to correctly
implement the functionality for filesystems that do not implement a
VOP_ALLOCATE.

Note that __FreeBSD_version was already bumped today to 900036 for any
ports which would like to use this function.

Also reserve space in the syscall table for posix_fadvise(2).

e2c83f74f4 Fix a bug in the userland rpc library, where it would use a
negative return value from write to update its position in
a buffer. The patch, courtesy of Andrey Simonenko, also simplifies
a conditional by removing the "i != cnt" clause, since it is
always true at this point in the code. The bug caused problems
for mountd, when it generated a large reply to an exports RPC
request.

2973057493 Allow strerror(0) and strerror_r(0, ...).
Of course, strerror_r() may still fail with ERANGE.

Although the POSIX specification said this could fail with EINVAL and
doing this likely indicates invalid use of errno, most other
implementations permitted it, various POSIX testsuites require it to
work (matching the older sys_errlist array) and apparently some
applications depend on it.

1e3f14466b * Add the readline(3) API to libedit. The libedit versions of
{readline,history}.h are in /usr/include/edit so as to not conflict with
  the GNU libreadline versions.  To use the libedit readline(3) one should
  add "-I/usr/include/edit" to their Makefile
  (spelled "-I${DESTDIR}/${INCLUDEDIR}/edit" within the FreeBSD source tree).

* Enable its use in the BSD licensed utilities that support readline(3).

* To make it easier to sync libedit development with NetBSD, histedit.h
  is moved into libedit's directory as history shows shown we keep merging
  it into that location.

681ff708cf From fts.c comment:
The "FTS_NOSTAT" option can avoid a lot of calls to stat(2) if it knows that a
directory could not possibly have subdirectories. This is decided by looking at
the link count: a subdirectory would increment its parent's link count by
virtue of its own ".." entry.  This assumption only holds for UFS-like
filesystems that implement links and directories this way, so we must punt for
others.

It looks like ZFS is a UFS-like file system, as the above also holds for ZFS.
Add ZFS to the list of file systems that allow for such optimization.
