Currently patch-id as used in rebase and cherry-pick does not account
for file modes if the file is modified. One consequence of this is
that if you have a local patch that changes modes, but upstream
has applied an outdated version of the patch that doesn't include
that mode change, "git rebase" will drop your local version of the
patch along with your mode changes. It also means that internal
patch-id doesn't produce the same output as the builtin, which does
account for mode changes due to them being part of diff output.
Fix by adding mode to the patch-id if it has changed, in the same
format that would be produced by diff, so that it is compatible
with builtin patch-id.

Patch-ids for binary patches are found by hashing the object
ids of the before and after objects in succession. However in
the --stable case, there is a bug where hunks are not flushed
for binary and header-only patch ids, which would always result
in a patch-id of 0000. The --unstable case is currently correct.
Reorder the logic to branch into 3 cases for populating the
patch body: header-only which populates nothing, binary which
populates the object ids, and normal which populates the text
diff. All branches will end up flushing the hunk.
Don't populate the ---a/ and +++b/ lines for binary diffs, to correspond
to those lines not being present in the "git diff" text output.
This is necessary because we advertise that the patch-id calculated
internally and used in format-patch is the same that what the
builtin "git patch-id" would produce when piped from a diff.
Update the test to run on both binary and normal files.

Carefully excluding t3404, which sees independent development elsewhere
at the time of writing, we use `main` as the default branch name in
t34*. This trick was performed via
$ (cd t &&
sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \
-e 's/Master/Main/g' -- t34*.sh &&
git checkout HEAD -- t34\*)
This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main`
for those tests.

In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:
$ git checkout HEAD -- \
t/t0027-auto-crlf.sh t/t0060-path-utils.sh \
t/t1011-read-tree-sparse-checkout.sh \
t/t1305-config-include.sh t/t1309-early-config.sh \

t/t5614-clone-submodules-shallow.sh \
t/t7508-status.sh t/t7606-merge-custom.sh \
t/t9302-fast-import-unpack-limit.sh
We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:
$ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' t/t980[0167]*.sh t/t9811*.sh

When t3419 was originally written, it was designed to run a smaller test
for correctness, and then the same test with a larger number of patches
for performance. But it seems unlikely the latter was helping us:
- it was marked with EXPENSIVE, so hardly anybody ran it anyway
- there's no indication that it was more likely to find bugs than the
smaller case (the commit message isn't very helpful, but the original
cover letter describes it as: "The first patch adds correctness and
(optional) performance tests".
- the timing results are shown only via test_debug(). So also not run
unless the user says "-d", and then not provided in any
machine-readable form.
If we're interested in performance regressions, a script in t/perf would
be more appropriate. I didn't add one here, because it's not at all
clear to me that what the script is timing is even all that interesting.
Let's simplify the script by dropping the EXPENSIVE run. That in turn
lets us drop the do_tests() wrapper, which lets us consistently use
single-quotes for our test snippets. And we can drop the useless
test_debug() timings, as well as their run() helper. And finally, while
we're here, we can replace the count() helper with the standard
test_seq().

This test runs a function which itself runs several assertions. The
last of these assertions cleans up the .git/rebase-apply directory,
since when run with EXPENSIVE set, the function is invoked a second time
to run the same tests with a larger data set.
However, as of 2ac0d6273f ("rebase: change the default backend from "am"
to "merge"", 2020-02-15), the default backend of rebase has changed, and
cleaning up the rebase-apply directory has no effect: it no longer
exists, since we're using rebase-merge instead.
Since we don't really care which rebase backend is in use, let's just
use the command "git rebase --quit", which will do the right thing
regardless.

A few tests here use double-quotes around the snippets of
shell code to run the tests. None of these tests wants to do
any interpolation at all, and it just leads to an extra
layer of quoting around all double-quotes and dollar signs
inside the snippet. Let's switch to single quotes, like
most other test scripts.

Two tests (t3302 and t3419) used to have their own environment
variable to trigger expensive tests without enabling expensive
tests in other scripts; a user could set GIT_NOTES_TIMING_TESTS
but not GIT_TEST_LONG and run the whole test suite and trigger
expensive tests only in t3302 but not other tests. The same for
GIT_PATCHID_TIMING_TESTS in t3419.
While this may have seemed a good flexibility, in reality if you are
concentrating on a single test (e.g. t3302), you can just run that
single test with the GIT_TEST_LONG to trigger expensive tests. It
does not seem worth forcing other people who may want to come up
with their own expensive tests to invent new environment variables
by keeping this convention.
Drop them.

This was only necessary because do_tests helper the script defines
took its parameters in a wrong order. Just pass an empty string (or
not passing the optional EXPENSIVE prerequisite) when running the
test with a light-weight set of parameters and have the shell do the
right thing when parsing test_expect_success helper.
Also update coding style while we are at it.

Some shells, for example dash versions older than 0.5.4, need to
spell a variable reference as '$N' rather than 'N' in an arithmetic
expansion. In order to avoid the syntax error, we change the
offending variable reference from 'i' to '$i' in function scramble.
There is nothing bash specific to this test script (and we shouldn't
have any bash dependent test). Fix its shebang line.
