Merge branch 'jc/prune-all' into jch

We used the approxidate() parser for "--expire=<timestamp>" options
of various commands, but it is better to treat --expire=all and
--expire=now a bit more specially than using the current timestamp.
Update "git gc" and "git reflog" with a new parsing function for
expiry dates.

Merge branch 'jh/checkout-auto-tracking' into jch

Updates "git checkout foo" that DWIMs the intended "upstream" and
turns it into "git checkout -t -b foo remotes/origin/foo" to
correctly take existing remote definitions into account.  The
remote "origin" may be what uniquely map its own branch to
remotes/some/where/foo but that some/where may not be "origin".

  glossary: Update and rephrase the definition of a remote-tracking branch
  branch.c: Validate tracking branches with refspecs instead of refs/remotes/*

Merge branch 'as/check-ignore' into jch

Enhance "check-ignore" (1.8.2 update) to work more like "check-attr"
over bidi-pipes.

Will wait for a follow-up.

The test in the second from the tip needs to be updated.

  completion: use __gitcompadd for __gitcomp_file
  completion; remove unuseful comments
  completion: document tilde expansion failure in tests
  completion: add file completion tests
test output: respect $TEST_OUTPUT_DIRECTORY

Most test results go in $TEST_OUTPUT_DIRECTORY, but the output files for
tests run with --tee or --valgrind just use bare "test-results".
Changes these so that they do respect $TEST_OUTPUT_DIRECTORY.

As a result of this, the valgrind/analyze.sh script may no longer
inspect the correct files so it is also updated to respect
$TEST_OUTPUT_DIRECTORY by adding it to GIT-BUILD-OPTIONS.  This may be a
regression for people who have TEST_OUTPUT_DIRECTORY in their config.mak
but want to override it in the environment, but this change merely
brings it into line with GIT_TEST_OPTS which already cannot be
overridden if it is specified in config.mak.
