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.

Several of the subcommands of `test-helper read-midx` do not close the

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.
