As per IEEE Std 1003.1-2008, -F "str" is now consistent with
-v FS="str" when str is null. Thanks to Warner Losh.

Fix readrec's definition of a record. This fixes an issue
with NetBSD's RS regular expression support that can cause
an infinite read loop. Thanks to Miguel Pineiro Jr.
Fix regular expression RS ^-anchoring. RS ^-anchoring needs to
know if it is reading the first record of a file. This change
restores a missing line that was overlooked when porting NetBSD's
RS regex functionality. Thanks to Miguel Pineiro Jr.
Fix size computation in replace_repeat() for special case
REPEAT_WITH_Q. Thanks to Todd C. Miller.
Also, included the tests from upstream, though they aren't yet connected
to the tree.

Import the latest bsd-features branch of the one-true-awk upstream:
o Move to bison for $YACC
o Set close-on-exec flag for file and pipe redirects that aren't std*
o lots of little fixes to modernize ocde base
o free sval member before setting it
o fix a bug where a{0,3} could match aaaa
o pull in systime and strftime from NetBSD awk
o pull in fixes from {Net,Free,Open}BSD (normalized our code with them)
o add BSD extensions and, or, xor, compl, lsheift, rshift (mostly a nop)
Also revert a few of the trivial FreeBSD changes that were done slightly
differently in the upstreaming process. Also, our PR database may have
been mined by upstream for these fixes, and Mikolaj Golub may deserve
credit for some of the fixes in this update.

Note: this backs out a number of changes we've made to awk because
they aren't upstream, but are on the vendor branch. Those will be
reapplied. svn makes it needlessly difficult to know which ones, but
at least r315426, r301289, and maybe r301691, though there may be
others too. None of these are critical, so bisecting through this
point is safe for all but awk regression tests :).
