We read a bunch of configs in `use_sideband_colors()` to configure the
colors that Git should use. We never free the strings read from the
config though, causing memory leaks.
Refactor the code to use `git_config_get_string_tmp()` instead, which
does not allocate memory. As we throw the strings away after parsing
them anyway there is no need to use allocated strings.

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

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.

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.

We populate a `struct symdiff` in case the user has requested a

indicates which commits shall be ignored in the diff. But while this
bitmap is dynamically allocated, we never free it.

that does this for us.

The userdiff structures may be initialized either statically on the
stack or dynamically via configuration keys. In the latter case we end
up leaking memory because we didn't have any infrastructure to discern
those strings which have been allocated statically and those which have
been allocated dynamically.
Refactor the code such that we have two pointers for each of these
strings: one that holds the value as accessed by other subsystems, and
one that points to the same string in case it has been allocated. Like
this, we can safely free the second pointer and thus plug those memory
leaks.

When provided a pointer to a destination index, then `unpack_trees()`
will end up copying its `o->internal.result` index into the provided
pointer. In those cases it is thus not necessary to free the index, as
we have transferred ownership of it.
There are cases though where we do not end up transferring ownership of
the memory, but `clear_unpack_trees_porcelain()` will never discard the
index in that case and thus cause a memory leak. And right now it cannot
do so in the first place because we have no indicator of whether we did
or didn't transfer ownership of the index.
Adapt the code to zero out the index in case we transfer its ownership.
Like this, we can now unconditionally discard the index when being asked
to clear the `unpack_trees_options`.

We conditionally release the index used for reading gitattributes in
merge-ort based on whether or the index has been populated. This check
uses `cache_nr` as a condition. This isn't sufficient though, as the
variable may be zero even when some other parts of the index have been
populated. This leads to memory leaks when sparse checkouts are in use,
as we may not end up releasing the sparse checkout patterns.
Fix this issue by unconditionally releasing the index.

When resolving revisions in `get_tags_and_duplicates()`, we only
partially manage the lifetime of `full_name`. In fact, managing its
lifetime properly is almost impossible because we put direct pointers to
that variable into multiple lists without duplicating the string. The
consequence is that these strings will ultimately leak.
Refactor the code to make the lists we put those names into duplicate
the memory. This allows us to properly free the string as required and
thus plugs the memory leak.
While this requires us to allocate more data overall, it shouldn't be
all that bad given that the number of allocations corresponds with the
number of command line parameters, which typically aren't all that many.

We allocate a `struct notes_tree` in `merge_commit()` which we then
initialize via `init_notes()`. It's not really necessary to allocate the

Furthermore, the allocation leads to a memory leak because despite its
name, `free_notes()` doesn't free the `notes_tree` but only clears it.
