The previous commit implemented a C version of the t0021/rot13-filter.pl
script. Let's use this new C helper to eliminate the PERL prereq from
various tests, and also remove the superseded Perl script.

At the end of `git checkout <pathspec>`, we get a message informing how
many entries were updated in the working tree. However, this number can
be inaccurate for two reasons:
1) Delayed entries currently get counted twice.
2) Failed entries are included in the count.
The first problem happens because the counter is first incremented
before inserting the entry in the delayed checkout queue, and once again
when finish_delayed_checkout() calls checkout_entry(). And the second
happens because the counter is incremented too early in
checkout_entry(), before the entry was in fact checked out. Fix that by
moving the count increment further down in the call stack and removing
the duplicate increment on delayed entries. Note that we have to keep
a per-entry reference for the counter (both on parallel checkout and
delayed checkout) because not all entries are always accumulated at the
same counter. See checkout_worktree(), at builtin/checkout.c for an
example.

After checkout, git usually reports how many entries were updated at
that operation. However, because we count the entries too soon during
the checkout process, we may actually include entries that do not get
properly checked out in the end. This can lead to an inaccurate final
report if the user expects it to show only the *successful* updates.
This will be fixed in the next commit, but for now let's document it
with a test that cover all checkout modes.
Note that `test_checkout_workers` have to be slightly adjusted in order
to use the construct `test_checkout_workers ... test_must_fail git
checkout`. The function runs the command given to it with an assignment
prefix to set the GIT_TRACE2 variable. However, this this assignment has
an undefined behavior when the command is a shell function (like
`test_must_fail`). As POSIX specifies:
If the command name is a function that is not a standard utility
implemented as a function, variable assignments shall affect the
current execution environment during the execution of the function. It
is unspecified:
- Whether or not the variable assignments persist after the
completion of the function
- Whether or not the variables gain the export attribute during the
execution of the function
Thus, in order to make sure the GIT_TRACE2 value gets visible to the git
command executed by `test_must_fail`, export the variable and run git in
a subshell.

t2080 makes a few copies of a test repository and later performs a
branch switch on each one of the copies to verify that parallel checkout
and sequential checkout produce the same results. However, the
repository is copied with `cp -R` which, on some systems, defaults to
following symlinks on the directory hierarchy and copying their target
files instead of copying the symlinks themselves. AIX is one example of
system where this happens. Because the symlinks are not preserved, the
copied repositories have paths that do not match what is in the index,
causing git to abort the checkout operation that we want to test. This
makes the test fail on these systems.
Fix this by copying the repository with the POSIX flag '-P', which
forces cp to copy the symlinks instead of following them. Note that we
already use this flag for other cp invocations in our test suite (see
t7001). With this change, t2080 now passes on AIX.

Add tests to populate the working tree during clone and checkout using
sequential and parallel mode, to confirm that they produce identical
results. Also test basic checkout mechanics, such as checking for
symlinks in the leading directories and the abidance to --force.
Note: some helper functions are added to a common lib file which is only
included by t2080 for now. But they will also be used by other
parallel-checkout tests in the following patches.
