When commands are started from a subdirectory, they may have to
compare the path to the subdirectory (called prefix and found out
from $(pwd)) with the tracked paths. On macOS, $(pwd) and
readdir() yield decomposed path, while the tracked paths are
usually normalized to the precomposed form, causing mismatch. This
has been fixed by taking the same approach used to normalize the
command line arguments.

Add assertions of the correct parameter count of various functions, in

guard other similar functions from the same sort of misuse.

Remove the optional "diagnostics" parameter of the
test_path_is_{file,dir,missing} functions.
We have a lot of uses of these functions, but the only legitimate use
of the diagnostics parameter is from when the functions themselves
were introduced in 2caf20c52b7 (test-lib: user-friendly alternatives
to test [-d|-f|-e], 2010-08-10).
But as the the rest of this diff demonstrates its presence did more to
silently introduce bugs in our tests. Fix such bugs in the tests added
in ae4e89e549b (gc: add --keep-largest-pack option, 2018-04-15), and
c04ba51739a (t6046: testcases checking whether updates can be skipped
in a merge, 2018-04-19).
Let's also assert that those functions are called with exactly one
parameter, a follow-up commit will add similar asserts to other
functions in test-lib-functions.sh that we didn't have existing misuse
of.

Currently invalid boolean config values return messages about 'bad
numeric', which is slightly misleading when the error was due to a
boolean value. We can improve the developer experience by returning a
boolean error message when we know the value is neither a bool text or
int.
before with an invalid boolean value of `non-boolean`, its unclear what
numeric is referring to:
fatal: bad numeric config value 'non-boolean' for 'commit.gpgsign': invalid unit
now the error message mentions `non-boolean` is a bad boolean value:
fatal: bad boolean config value 'non-boolean' for 'commit.gpgsign'

Currently, the options for the `list` and `show` subcommands are just
listed as `<options>`. This seems to imply, from a cursory glance at the
summary, that they take the stash options listed below. However, reading
more carefully, we see that they take log options and diff options
respectively.
Make it more obvious that they take log and diff options by explicitly
stating this in the subcommand summary.

Whenever a user runs `git reflog expire --stale-fix`, the most likely
reason is that their repository is at least _somewhat_ corrupt. Which
means that it is more than just possible that some objects are missing.
If that is the case, that can currently let the command abort through
the phase where it tries to mark all reachable objects.
Instead of adding insult to injury, let's be gentle and continue as best
as we can in such a scenario, simply by ignoring the missing objects and
moving on.

Fix a memory leak in 296d4a94e7 (diff: add -I<regex> that ignores
matching changes, 2020-10-20) by freeing the memory it allocates in
the newly introduced diff_free(). See the previous commit for details
on that.
This memory leak was intentionally introduced in 296d4a94e7, see the
discussion on a previous iteration of it in
https://lore.kernel.org/git/xmqqeelycajx.fsf@gitster.c.googlers.com/
At that time freeing the memory was somewhat tedious, but since it
isn't anymore with the newly introduced diff_free() let's use it.
Let's retain the pattern for diff_free_file() and add a
diff_free_ignore_regex(), even though (unlike "diff_free_file") we
don't need to call it elsewhere. I think this'll make for more
readable code than gradually accumulating a giant diff_free()
function, sharing "int i" across unrelated code etc.

Add a diff_free() function to free anything we may have allocated in
the "diff_options" struct, and the ability to make calling it a noop
by setting "no_free" in "diff_options".
This is required because when e.g. "git diff" is run we'll allocate
things in that struct, use the diff machinery once, and then exit.
But if we run e.g. "git log -p" we're going to re-use what we
allocated across multiple diff_flush() calls, and only want to free
things at the end.
We've thus ended up with features like the recently added "diff -I"[1]
where we'll leak memory. As it turns out it could have simply used the
pattern established in 6ea57703f6 (log: prepare log/log-tree to reuse
the diffopt.close_file attribute, 2016-06-22).
Manually adding more such flags to things log_tree_commit() every time
we need to allocate something would be tedious. Let's instead move
that fclose() code it to a new diff_free(), in anticipation of freeing
more things in that function in follow-up commits.
Some functions such as log_tree_commit() need an idiom of optionally
retaining a previous "no_free", as they may either free the memory
themselves, or their caller may do so. I'm keeping that idiom in
log_show_early() for good measure, even though I don't think it's
currently called in this manner. It also gets passed an existing
"struct rev_info", so future callers may want to set the "no_free"
flag.
This change is a bit hard to read because while the freeing pattern
we're introducing isn't unusual, the "file" member is a special
snowflake. We usually don't want to fclose() it. This is because
"file" is usually stdout, in which case we don't want to fclose()
it. We only want to opt-in to closing it when we e.g. open a file on
the filesystem. Thus the opt-in "close_file" flag.
So the API in general just needs a "no_free" flag to defer freeing,
but the "file" member still needs its "close_file" flag. This is made
more confusing because while refactoring this code we could replace
some "close_file=0" with "no_free=1", whereas others need to set both
flags.
This is because there were some cases where an existing "close_file=0"
meant "let's defer deallocation", and others where it meant "we don't
want to close this file handle at all".
