When writing an MIDX in git-repack(1) we first collect all the pack
names that we want to add to it in a string list. This list is marked as
`NODUP`, which indicates that it will neither duplicate nor own strings
added to it. In `write_midx_included_packs()` we then `insert()` strings
via `xstrdup()` or `strbuf_detach()`, but the resulting strings will not
be owned by anything and thus leak.
Fix this issue by marking the list as `DUP` and using a local buffer to
compute the pack names.
This leak is hit in t5319, but plugging it is not sufficient to make the
whole test suite pass.

When writing the MIDX file we first create the `struct hashfile` used to
write the trailer hash, and then afterwards we verify whether we can
actually write the MIDX in the first place. When we decide that we
can't, this leads to a memory leak because we never free the hash file
contents.
We could fix this by freeing the hashfile on the exit path. There is a
better option though: we can simply move the checks for the error
condition earlier. As there is no early exit between creating the
hashfile and finalizing it anymore this is sufficient to fix the memory
leak.
While at it, also move around the block checking for `ctx.entries_nr`.
This change is not required to fix the memory leak, but it feels natural
to move together all massaging of parameters before we go with them and
execute the actual logic.

The "--output" switch is an `OPT_FILENAME()` option, which allocates
memory when specified by the user. But while we free the string when
executed without the "--remote" switch, we don't otherwise because we
return via a separate exit path that doesn't know to free it.
Fix this by creating a common exit path.

In git-upload-archive(1), we pass an array of arguments to
`write_archive()` to tell it what exactly to do. We don't ever clear the
vector though, causing a memory leak. Furthermore though, the call to
`write_archive()` may cause contents of the array to be modified, which
would cause us to leak memory to allocated strings held by it.
Fix the issue by having `write_archive()` create a shallow copy of
`argv` before parsing the arguments. Like this, we won't modify the
caller's array and can easily `strvec_clear()` it to plug these memory
leaks.

The `format_set_trailers_options()` function is responsible for parsing
a custom pretty format for trailers. It puts the parsed options into a
`struct process_trailer_options` structure, while the allocated memory
required for this will be put into separate caller-provided arguments.
It is thus the caller's responsibility to free the memory not via the
options structure, but via the other parameters.
While we do this alright for the separator and filter keys, we do not
free the memory associated with the key/value separator. Fix this to
plug this memory leak.

When parsing pretty formats from the config we leak the name and user
format whenever these are set multiple times. This is because we do not
free any already-set value in case there is one.
Plugging this leak for the name is trivial. For the user format we need
to be a bit more careful, because we may end up assigning a pointer into
the allocated region when the string is prefixed with either "format" or
"tformat:". In order to make it safe to unconditionally free the user
format we thus strdup the stripped string into the field instead of a
pointer into the string.

We populate the `mailinfo` arrays `p_hdr_data` and `s_hdr_data` with
data parsed from the mail headers. These arrays may end up being only
partially populated with gaps in case some of the headers do not parse
properly. This causes memory leaks because `strbuf_list_free()` will
stop iterating once it hits the first `NULL` pointer in the backing
array.
Fix this by open-coding a variant of `strbuf_list_free()` that knows to
iterate through all headers.

Enable Git to resolve its own binary location using __getprogramdir
and getprogname.
Since /proc is not a mandatory filesystem on z/OS, we cannot rely on the
git_get_exec_path_procfs method to determine Git's executable path. To
address this, we have implemented git_get_exec_path_zos, which resolves
the executable path by extracting it from the current program's
directory and filename.

The `reftable_table` interface provides a generic infrastructure that
can abstract away whether the underlying table is a single table, or a
merged table. This abstraction can make it rather hard to reason about
the code. We didn't ever use it to implement the reftable backend, and
with the preceding patches in this patch series we in fact don't use it
at all anymore. Furthermore, it became somewhat useless with the recent
refactorings that made it possible to seek reftable iterators multiple
times, as these now provide generic access to tables for us. The
interface is thus redundant and only brings unnecessary complexity with
it.
Remove the `struct reftable_table` interface and its associated
functions.

The `struct reftable_table` interface in our "reftable" test helper gets
used such that we can easily print either a single table, or a merged
stack. This generic interface is about to go away.
Prepare the code for this change by using merged tables instead. When
printing the stack we've already got one. When using a single table, we
can create a merged table from it to adapt.
This removes the last user of the generic interface.

The "reftable" test helper uses a hand-crafted version to convert from a
raw hash to its hex variant. This was done because this code used to be
part of the reftable library, where we do not use most functions from
the Git core.
Now that the code is integrated into the "dump-reftable" helper though,
that limitation went away. Let's thus use `hash_to_hex_algop()` instead.

This follows the same reasoning as the preceding commit.
Note that this requires us to remove the tests for this functionality in
`reftable/stack_test.c`. The test does not really add much anyway,
because all it verifies is that we do not crash or run into an error,
and it specifically doesn't check the outputted data. Also, as the code
is now part of the test helper, it doesn't make much sense to have a
unit test for it in the first place.

The printing functionality part of `reftable/dump.c` is really only used
by our "dump-reftable" test helper. It is certainly not generic logic
that is useful to anybody outside of Git, and the format it generates is
quite specific. Still, parts of it are used in our test suite and the
output may be useful to take a peek into reftable stacks, tables and
blocks. So while it does not make sense to expose this as part of the
reftable library, it does make sense to keep it around.
Inline the `reftable_dump_main()` function into the "dump-reftable" test
helper. This clarifies that its format is subject to change and not part
of our public interface. Furthermore, this allows us to iterate on the
implementation in subsequent patches.

The filtering ref iterator can be used to only yield refs which are not
in a specific skip list. This iterator has an option to double-check the
results it returns, which causes us to seek the reference we are about
to yield via a separate table such that we detect whether the reference
that the first iterator has yielded actually exists.
The value of this is somewhat dubious, and I cannot think of any usecase
where this functionality should be required. Furthermore, this option is
never set in our codebase, which means that it is essentially untested.
And last but not least, the `struct reftable_table` that is used to
implement it is about to go away.
So while we could refactor the code to not use a `reftable_table`, it
very much feels like a wasted effort. Let's just drop this code.

The merged table provides access to a reftable stack by merging the
contents of those tables into a virtual table. These subtables are being
tracked via `struct reftable_table`, which is a generic interface for
accessing either a single reftable or a merged reftable. So in theory,
it would be possible for the merged table to merge together other merged
tables.
This is somewhat nonsensical though: we only ever set up a merged table
over normal reftables, and there is no reason to do otherwise. This
generic interface thus makes the code way harder to follow and reason
about than really necessary. The abstraction layer may also have an
impact on performance, even though the extra set of vtable function
calls probably doesn't really matter.
Refactor the merged tables to use a `struct reftable_reader` for each of
the subtables instead, which gives us direct access to the underlying
tables. Adjust names accordingly.

In t7900, we exercise the `--detach` logic by checking whether the
command ended up writing anything to its output or not. This supposedly
works because we close stdin, stdout and stderr when daemonizing. But
one, it breaks on platforms where daemonize is a no-op, like Windows.
And second, that git-maintenance(1) outputs anything at all in these
tests is a bug in the first place that we'll fix in a subsequent commit.
Introduce a new trace2 region around the detach which allows us to more
explicitly check whether the detaching logic was executed. This is a
much more direct way to exercise the logic, provides a potentially
useful signal to tracing logs and also works alright on platforms which
do not have the ability to daemonize.

block_iter_reset() restores a block iterator to its state at the time
of initialization without freeing any memory while block_iter_close()
deallocates the memory for the iterator.
In the current testing setup, a block iterator is allocated and
deallocated for every iteration of a loop, which hurts performance.
Improve upon this by using block_iter_reset() at the start of each
iteration instead. This has the added benifit of testing
block_iter_reset(), which currently remains untested.
Similarly, remove reftable_record_release() for a reftable record
that is still in use.

rebase --exec doesn't obey --quiet and ends up printing messages about
the command being executed:
git rebase HEAD~3 --quiet --exec true
Executing: true
Executing: true
Executing: true
Let's fix that by omitting the "Executing" messages when using --quiet.
Furthermore, the sequencer code includes a few calls to
term_clear_line(), which prints a special character sequence to erase
the previous line displayed on stderr (even when nothing was printed
yet). For an user running the command interactively, the net effect of
calling this function with or without --quiet is the same as the
characters are invisible in the terminal. However, when redirecting the
output to a file or piping to another command, the presence of these
invisible characters is noticeable, and it may break user expectation as
--quiet is not being respected.
We could skip the term_clear_line() calls when --quiet is used, like we
are doing with the "Executing" messages, but it makes much more sense to
condition the line cleaning upon stderr being TTY, since these
characters are really only useful for TTY outputs.
The added test checks for both these two changes.
