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.

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

-w flag matching with an empty pattern was generally 'broken', allowing
matches to occur on any line whether or not it actually matches -w
criteria.
This fix required a good amount of refactoring to address. procline()
is altered to *only* process the line and return whether it was a match
or not, necessary to be able to short-circuit the whole function in case
of this matchall flag. -m flag handling is moved out as well because it
suffers from the same fate as context handling if we bypass any actual
pattern matching.
The matching context (matches, mostly) didn't previously exist outside
of procline(), so we go ahead and create context object for file
processing bits to pass around. grep_printline() was created due to
this, for the scenarios where the matches don't actually matter and we
just want to print a line or two, a la flushing the context queue and
no -o or --color specified.
Damage from this broken behavior would have been mitigated by the fact
that it is unlikely users would invoke grep -w with an empty pattern.
This was identified while checking PR 105221 for problems it this may
cause in BSD grep, but PR 105221 is *not* a report of this behavior.

-w and -v flag matching was mostly functional but had some minor
problems:
1. -w flag processing only allowed one iteration through pattern
matching on a line. This was problematic if one pattern could match
more than once, or if there were multiple patterns and the earliest/
longest match was not the most ideal, and
2. Previous work "fixed" things to not further process a line if the
first iteration through patterns produced no matches. This is clearly
wrong if we're dealing with the more restrictive -w matching.
#2 breakage could have also occurred before recent broad rewrites, but
it would be more arbitrary based on input patterns as to whether or not
it actually affected things.
Fix both of these by forcing a retry of the patterns after advancing
just past the start of the first match if we're doing more restrictive
-w matching and we didn't get any hits to start with. Also move -v flag
processing outside of the loop so that we have a greater change to match
in the more restrictive cases. This wasn't strictly wrong, but it could
be a little more error prone.
While here, introduce some regressions tests for this behavior and fix
some excessive wrapping nearby that hindered readability. GNU grep
passes these new tests.
