r265408 renamed tcps_rcvmemdrop to tcps_rcvreassfull and gave it a more
specific description. r279122 (libxo-ification) reverted that change.
This commit brings it back, but with a small tweak to the description.

This uses the same logic as with the -s option, first validating the
entered value, then storing the result in a struct timeval.

X-MFC-With: r352818
In r334906, the -s option was changed to allow fractional times, but
this only functioned correctly for batch mode. In interactive mode, any
delay below 1.0 would get floored to zero. This would put top(1) into a
tight loop, which could be difficult to interrupt.
Fix this by storing the -s option value (after validation) into a struct
timeval, and using that struct consistently for delaying with select(2).
Next up is to allow interactive entry of a fractional delay value.

Add an atomic shm rename operation, similar in spirit to a file
rename. Atomically unlink an shm from a source path and link it to a
destination path. If an existing shm is linked at the destination
path, unlink it as part of the same atomic operation. The caller needs
the same permissions as shm_unlink to the shm being renamed, and the
same permissions for the shm at the destination which is being
unlinked, if it exists. If those fail, EACCES is returned, as with the
other shm_* syscalls.
truss support is included; audit support will come later.
This commit includes only the implementation; the sysent-generated
bits will come in a follow-on commit.

When an empty pattern is encountered in the pattern list, I had previously
broken bsdgrep to count that as a "match all" and ignore any other patterns
in the list. This commit rectifies that mistake, among others:
- The -v flag semantics were not quite right; lines matched should have been
counted differently based on whether the -v flag was set or not. procline
now definitively returns whether it's matched or not, and interpreting
that result has been kicked up a level.
- Empty patterns with the -x flag was broken similarly to empty patterns
with the -w flag. The former is a whole-line match and should be more
strict, only matching blank lines. No -x and no -w will will match the
empty string at the beginning of each line.
- The exit code with -L was broken, w.r.t. modern grep. Modern grap will
exit(0) if any file that didn't match was output, so our interpretation
was simply backwards. The new interpretation makes sense to me.
Tests updated and added to try and catch some of this.
This misbehavior was found by autoconf while fixing ports found in PR 229925

The way jot(1) defaults missing arguments doesn't match the behaviour
described in the manpage, which states that with fewer than 3 arguments
missing values are supplied from left to right.
In fact, with one or two arguments, the last (s which is step size or seed)
defaults to 1 (or -1 if begin and end specify a descending range), and then
omitted arguments are set to default starting with the leftmost until three
arguments are available.
This is why `jot 2 1000` prints 1000 and 1001 instead of 1000 and 100.

To remain compatible with GNU patch, we should ensure that once we're
removing empty files after a reversed /dev/null patch we don't remove files
that have been modified. GNU patch leaves these intact and just reverses the
hunk that created the file, effectively implying --remove-empty-files for
reversed /dev/null patches.
All of them are needed to be able to boot to single user and be able
to repair a existing FreeBSD installation so put them directly into
FreeBSD-runtime.

Summary:
- basic: test application of patches created by diff -u at the
beginning/middle/end of file, which have differing amounts of context
before and after chunks being added
- limited_ctx: stems from PR 74127 in which a rogue line was getting added
when the patch should have been rejected. Similar behavior was
reproducible with larger contexts near the beginning/end of a file. See
r326084 for details
- file_creation: patch sourced from /dev/null should create the file
- file_nodupe: said patch sourced from /dev/null shouldn't dupe the contents
when re-applied (personal vendetta, WIP, see comment)
- file_removal: this follows from nodupe; the reverse of a patch sourced
from /dev/null is most naturally deleting the file, as is expected based
on GNU patch behavior (WIP)
Some of the procstat tests start a program "while1" and examine the process

Instead, have "while1" write something when it starts, and use a fifo to
