38325e2ab8 bsdgrep(1): various fixes of empty pattern/exit code/-c behavior
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
expecting either a more sane or a more GNU-like sed.

e48c002fa4 Relax time constraint in pthread_cond_timedwait unit test
pthread_cond_timedwait() should wait _at least_ until the timeout,
but it might appear to wait longer due to system activity and
scheduling.  The test ignored fractional seconds when comparing the
actual and expected timeouts, so it allowed anywhere between zero
and one extra second of wait time.  Zero is a bit unreasonable.
Compare fractional seconds so we always allow up to one extra second.

54a3a11421 Provide separate accounting for user-wired pages.
Historically we have not distinguished between kernel wirings and user
wirings for accounting purposes.  User wirings (via mlock(2)) were
subject to a global limit on the number of wired pages, so if large
swaths of physical memory were wired by the kernel, as happens with
the ZFS ARC among other things, the limit could be exceeded, causing
user wirings to fail.

The change adds a new counter, v_user_wire_count, which counts the
number of virtual pages wired by user processes via mlock(2) and
mlockall(2).  Only user-wired pages are subject to the system-wide
limit which helps provide some safety against deadlocks.  In
particular, while sources of kernel wirings typically support some
backpressure mechanism, there is no way to reclaim user-wired pages
shorting of killing the wiring process.  The limit is exported as
vm.max_user_wired, renamed from vm.max_wired, and changed from u_int
to u_long.

The choice to count virtual user-wired pages rather than physical
pages was done for simplicity.  There are mechanisms that can cause
user-wired mappings to be destroyed while maintaining a wiring of
the backing physical page; these make it difficult to accurately
track user wirings at the physical page layer.

The change also closes some holes which allowed user wirings to succeed
even when they would cause the system limit to be exceeded.  For
instance, mmap() may now fail with ENOMEM in a process that has called
mlockall(MCL_FUTURE) if the new mapping would cause the user wiring
limit to be exceeded.

Note that bhyve -S is subject to the user wiring limit, which defaults
to 1/3 of physical RAM.  Users that wish to exceed the limit must tune
vm.max_user_wired.

70c144dc78 nanosleep(2): Fix bogus incrementing of rmtp by tc_tick_sbt on [EINTR].
sbt is the time in the future that the tsleep_sbt() is expected to be completed
at.  sbtt is the current time.  Depending on the precision with sysctl
kern.timecounter.alloweddeviation the start time may be incremented by
tc_tick_sbt.  The same increment is needed for the current time of sbtt before
calculating the difference.  The impact of missing this increment is that rmtp
may increase by one tc_tick_sbt on every early [EINTR] return.  If the same
struct is passed in for rqtp as rmtp this can result in rqtp effectively
incrementing by tc_tick_sbt and sleeping longer than originally intended.

This problem was introduced in r247797.

Cases (1) and (3) should throw errors but they actually succeed, and (2)

was decided by comparing to the behavior with the equivalent BRE (1)(3) or

2b34e84335 Add abstime kqueue(2) timers and expand struct kevent members.
This change implements NOTE_ABSTIME flag for EVFILT_TIMER, which
specifies that the data field contains absolute time to fire the
event.

To make this useful, data member of the struct kevent must be extended
to 64bit.  Using the opportunity, I also added ext members.  This
changes struct kevent almost to Apple struct kevent64, except I did
not changed type of ident and udata, the later would cause serious API
incompatibilities.

The type of ident was kept uintptr_t since EVFILT_AIO returns a
pointer in this field, and e.g. CHERI is sensitive to the type
(discussed with brooks, jhb).

Unlike Apple kevent64, symbol versioning allows us to claim ABI
compatibility and still name the new syscall kevent(2).  Compat shims
are provided for both host native and compat32.

6d635d3b32 bsdgrep: Correct per-line line metadata printing
Metadata printing with -b, -H, or -n flags suffered from a few flaws:

1) -b/offset printing was broken when used in conjunction with -o

2) With -o, bsdgrep did not print metadata for every match/line, just
   the first match of a line

3) There were no tests for this

Address these issues by outputting this data per-match if the -o flag is
specified, and prior to outputting any matches if -o but not --color,
since --color alone will not generate a new line of output for every
iteration over the matches.

To correct -b output, fudge the line offset as we're printing matches.

While here, make sure we're using grep_printline in -A context.  Context
printing should *never* look at the parsing context, just the line.

The tests included do not pass with gnugrep in base due to it exhibiting
similar quirky behavior that bsdgrep previously exhibited.
