When we run a test helper function in test_submodule_switch_common(), we
sometimes specify a whole helper function as the $command. When we do
this, in some test cases, we just mark the whole function with
`test_must_fail`. However, it's possible that the helper function might
fail earlier or later than expected due to an introduced bug. If this
happens, then the test case will still report as passing but it should
really be marked as failing since it didn't actually display the
intended behaviour.
Instead of invoking `test_must_fail $command`, pass the string
"test_must_fail" as the second argument in case where the git command is
expected to fail.
When $command is a helper function, the parent function calling
test_submodule_switch_common() is test_submodule_switch_func(). For all
test_submodule_switch_func() invocations, increase the granularity of
the argument test helper function by prefixing the git invocation which is
meant to fail with the second argument like this:
$2 git checkout "$1"
In the other cases, test_submodule_switch() and
test_submodule_forced_switch(), instead of passing in the git command
directly, wrap it using the git_test_func() and pass the git arguments
using the global variable $gitcmd. Unfortunately, since closures aren't
a thing in shell scripts, the global variable is necessary. Another
unfortunate result is that the "git_test_func" will used as the test
case name when $command is printed but it's worth it for the cleaner
code.
Finally, as an added bonus, `test_must_fail` will now only run on git
commands.

Since all invocations of test_submodule_forced_switch() are git
commands, automatically prepend "git" before invoking
test_submodule_switch_common().
Similarly, many invocations of test_submodule_switch() are also git
commands so automatically prepend "git" before invoking
test_submodule_switch_common() as well.
Finally, for invocations of test_submodule_switch() that invoke a custom
function, rename the old function to test_submodule_switch_func().
This is necessary because in a future commit, we will be adding some
logic that needs to distinguish between an invocation of a plain git
comamnd and an invocation of a test helper function.

diff.submodule when set to log produces output which git-am cannot
handle. Ignore this setting when generating patch output.

git am will break when using diff.submodule=log; add some test cases
to illustrate this breakage as simply as possible. There are
currently two ways this can fail:
* With errors ("unrecognized input"), if only change
* Silently (no submodule change), if other files change
Test for both conditions and ensure without diff.submodule this works.

Test that the am command updates the work tree as expected (for submodule
changes which don't result in conflicts). To make that work add two
helper functions that use format-patch to create the input for am.
Add the KNOWN_FAILURE_NOFF_MERGE_ATTEMPTS_TO_MERGE_REMOVED_SUBMODULE_FILES
switch to expect the known failure that --no-ff merges attempt to merge
the new files in the former submodule directory with those of the removed
submodule.
