Not all systems have a readlink program available for use by the shell.
This causes t3210 to fail on at least AIX. Let's provide a perl
one-liner to do the same thing, and use it there.
I also updated calls in t9802. Nobody reported failure there, but it's
the same issue. Presumably nobody actually tests with p4 on AIX in the
first place (if it is even available there).
I left the use of readlink in the "--valgrind" setup in test-lib.sh, as
valgrind isn't available on exotic platforms anyway (and I didn't want
to increase dependencies between test-lib.sh and test-lib-functions.sh).
There's one other curious case. Commit d2addc3b96 (t7800: readlink may
not be available, 2016-05-31) fixed a similar case. We can't use our
wrapper function there, though, as it's inside a sub-script triggered by
Git. It uses a slightly different technique ("ls" piped to "sed"). I
chose not to use that here as it gives confusing "ls -l" output if the
file is unexpectedly not a symlink (which is OK for its limited use, but
potentially confusing for general use within the test suite). The perl
version emits the empty string.

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.

Using 'test_must_be_empty' is preferable to 'test ! -s', because it
gives a helpful error message if the given file is unexpectedly no
empty, while the latter remains completely silent. Furthermore, it
also catches cases when the given file unexpectedly does not exist at
all.
This patch was created by:
sed -i -e 's/test ! -s/test_must_be_empty/' t[0-9]*.sh

Update the git-p4 tests so that they work with both
Python2 and Python3.
We have to be explicit about the difference between
Unicode text strings (Python3 default) and raw binary
strings which will be exchanged with Perforce.
Additionally, print always takes parentheses in Python3.

Damien Gérard highlights an interesting problem. Some p4
repositories end up with symlinks that have an empty target. It
is not possible to create this with current p4, but they do
indeed exist.
The effect in git p4 is that "p4 print" on the symlink returns an
empty string, confusing the curret symlink-handling code.
Such broken repositories cause problems in p4 as well, even with
no git involved. In p4, syncing to a change that includes a
bogus symlink causes errors:
//depot/empty-symlink - updating /home/me/p4/empty-symlink
rename: /home/me/p4/empty-symlink: No such file or directory
and leaves no symlink.
In git, replicate the p4 behavior by ignoring these bad symlinks.
If, in a later p4 revision, the symlink happens to point to
something non-null, the symlink will be replaced properly.
Add a big test for all this too.
This happens to be a regression introduced by 1292df1 (git-p4:
Fix occasional truncation of symlink contents., 2013-08-08) and
appeared first in 1.8.5. But it shows up only in p4 repositories
of dubious character, so can wait for a proper release.

While this happens to work, there was no test to make sure
that the basic importing of a symlink from p4 to git functioned.
Add a simple test to create a symlink in p4 and import it into git,
then verify that the symlink exists and has the correct target.

Prior to commit fa83a33b, the 'git checkout' DWIMery would create a
new local branch if the specified branch name did not exist and it
matched exactly one ref in the "remotes" namespace. It searched
the "remotes" namespace for matching refs using a simple comparison
of the trailing portion of the remote ref names. This approach
could sometimes produce false positives or negatives.
Since fa83a33b, the DWIMery more strictly excludes the remote name
from the ref comparison by iterating through the remotes that are
configured in the .gitconfig file. This has the side-effect that
any refs that exist in the "remotes" namespace, but do not match
the destination side of any remote refspec, will not be used by
the DWIMery.
This change in behavior breaks the tests in t9802 which relied on
the old behavior of searching all refs in the remotes namespace,
since the git-p4 script does not configure any remotes in the
.gitconfig. Let's work around this in these tests by explicitly
naming the upstream branch to base the new local branch on when
calling 'git checkout'.

P4 stores newlines in the depos as \n. By default, git does this
too, both on unix and windows. Test to make sure that this stays
true.
Both git and p4 have mechanisms to use \r\n in the working
directory. Exercise these.

Python 2.4 lacks the following features:
subprocess.check_call
struct.pack_into
Take a cue from 460d1026 and provide an implementation of the
CalledProcessError exception. Then replace the calls to
subproccess.check_call with calls to subprocess.call that check the return
status and raise a CalledProcessError exception if necessary.
The struct.pack_into in t/9802 can be converted into a single struct.pack
call which is available in Python 2.4.

One of the filetypes that p4 supports is utf16. Its behavior is
odd in this case. The data delivered through "p4 -G print" is
not encoded in utf16, although "p4 print -o" will produce the
proper utf16-encoded file.
When dealing with this filetype, discard the data from -G, and
instead read the contents directly.
An alternate approach would be to try to encode the data in
python. That worked for true utf16 files, but for other files
marked as utf16, p4 delivers mangled text in no recognizable encoding.
Add a test case to check utf16 handling, and +k and +ko handling.
