In 't9811-git-p4-label-import.sh' the test 'tag that cannot be
exported' runs
!(p4 labels | grep GIT_TAG_ON_A_BRANCH)
to check that the given string is not printed by 'p4 labels'. This is
problematic, because according to POSIX [1]:
"If the pipeline begins with the reserved word ! and command1 is a
subshell command, the application shall ensure that the ( operator
at the beginning of command1 is separated from the ! by one or more
<blank> characters. The behavior of the reserved word ! immediately
followed by the ( operator is unspecified."
While most common shells still interpret this '!' as "negate the exit
code of the last command in the pipeline", 'mksh/lksh' don't and
interpret it as a negative file name pattern instead. As a result
they attempt to run a command made up of the pathnames in the current
directory (it contains a single directory called 'main'), which, of
course, fails the test.
We could fix it simply by adding a space between the '!' and '(', but
instead let's fix it by removing the unnecessary subshell.

Use 'test_atexit' to run cleanup commands to stop 'p4d' at the end of
the test script or upon interrupt or failure, as it is shorter,
simpler, and more robust than registering such cleanup commands in the
trap on EXIT in the test scripts.
Note that one of the test scripts, 't9801-git-p4-branch.sh', stops and
then re-starts 'p4d' twice in the middle of the script; take care that
the cleanup functions to stop 'p4d' are only registered once.
Note also that 'git p4' tests invoke different functions in the trap
on EXIT ('cleanup') and in the last test before 'test_done'
('kill_p4d'). Register both of these functions with 'test_atexit' for
now, and a a later patch in this series will then clean up the
redundancy.

With --detect-labels enabled, git-p4 will try to create tags
using git fast-import by writing a "tag" clause to the
fast-import stream.
If the commit that the tag references has not yet actually
been processed by fast-import, then the tag can't be created
and git-p4 fails to import the P4 label.
Teach git-p4 to use fast-import "marks" when creating tags
which reference commits created during the current run of the
program.
Commits created before the current run are still referenced
in the old way using a normal git commit.

When importing a label which references a commit that git-p4 does
not know about, git-p4 should skip it and go on to process other
labels that can be imported.
Instead it crashes when attempting to find the missing commit in
the git history. This test demonstrates the problem.

This adds a test for git p4 to check it can import/export tags
when enabled via a config variable rather than on the command
line.

The previous one is already in 'next' but was somewhat lacking.
The configuration "git-p4.validLabelRegexp" is now called
"labelExportRegexp", and its default covers lowercase alphabets as
well.

The existing label import code looks at each commit being
imported, and then checks for labels at that commit. This
doesn't work in the real world though because it will drop
labels applied on changelists that have already been imported,
a common pattern.
This change adds a new --import-labels option. With this option,
at the end of the sync, git p4 gets sets of labels in p4 and git,
and then creates a git tag for each missing p4 label.
This means that tags created on older changelists are
still imported.
Tags that could not be imported are added to an ignore
list.
The same sets of git and p4 tags and labels can also be used to
derive a list of git tags to export to p4. This is enabled with
--export-labels in 'git p4 submit'.
