9a9c6e39ba grep: fix -x -v with certain pattern orders
We found out that busybox -x -v is a bit broken:

ari@ari-thinkpad:~/busybox$ echo '  aa bb cc' | ./busybox grep -x -e 'aa.*' -e '.*bb.*'
  aa bb cc
ari@ari-thinkpad:~/busybox$ echo '  aa bb cc' | ./busybox grep -x -v -e 'aa.*' -e '.*bb.*'
ari@ari-thinkpad:~/busybox$ echo '  aa bb cc' | ./busybox grep -x -e '.*aa.*' -e 'bb.*'
  aa bb cc
ari@ari-thinkpad:~/busybox$ echo '  aa bb cc' | ./busybox grep -x -v -e '.*aa.*' -e 'bb.*'
  aa bb cc

Last one is wrong.

This patch fixes the issue by making sure that the variable 'found'
never makes a transition from 1 to 0, as this would mean that
grep previously found a match on this input line.

Unfortunately, with !EXTRA_COMPAT, "grep -w ^str" still erroneously matches "strstr".

5fc0585c01 grep: fix grep -x to not set REG_NOSUB
When -F isn't specified (and !ENABLE_EXTRA_COMPAT), grep -x uses
regexec's regmatch_t output to determine if the match was the entire
line. However it also set the REG_NOSUB flag which makes it ignore the
regmatch_t argument.

Add an exception to the setting of REG_NOSUB for OPT_x and add some test
cases to test the behaviour of -x.

4bb1b04fd1 Redo test suite to be able to test more than one command at a time. Eliminate
$COMMAND environment variable, instead put full command line (including
command to run) in second argument.  Modify $PATH to have test versions of
commands at start of path.  (Also more infrastructure for testing as root,
work in progress...)

48c6157eb9 Fix the test suite so that individual *.tests files can be run ala
COMMAND=sort ./sort.tests
So we can compare against non-busybox versions, and possibly our testsuite
will be useful to somebody like the Linux Test Project someday.

Redid testing.sh to add new command, "optional", to skip tests that require
certain features.  (use: `optional FEATURE_SORT_BIG`, or `optional ""` to
stop skipping.)  Note that optional is a NOP if the environment variable
"OPTIONFLAGS" is blank, so although we're marking up the tests with busybox
specific knowledge, it doesn't interfere with running the tests without
busybox.

Moved setting the "OPTIONFLAGS" environment variable to runtest.  Philosophy:
busybox-specific stuff belongs in runtest; both testing.sh and the tests
themselves should be as busybox-agnostic as possible.

Moved detecting that a command isn't in busybox at all (hence skipping the
entire command.tests file) to runtests.  Rationale: optional can't currently
test for more than one feature at a time, so if we clear anything with
optional "" we might perform tests we don't want to.

Marked up busybox.tests to know which tests need CAT enabled.  Fixed up other
tests to be happy with new notation.

I suspect egrep should be appended to grep.  It's a sub-feature, really...

This is used to see if given tests should be run (are available) or not.
  Print "UNTESTED: descr" if the applet or feature is not available.
- add _BB_CONFIG_DEP to existing new.tests
- move old grep test to new test infrastructure and add a few more test for
  grep.
