Fix a memory leak introduced in 9055e401dd (sequencer: introduce new
commands to reset the revision, 2018-04-25), which called
setup_unpack_trees_porcelain() without a corresponding call to
clear_unpack_trees_porcelain().
This introduces a change in behavior in that we now start calling
clear_unpack_trees_porcelain() even without having called the
setup_unpack_trees_porcelain(). That's OK, that clear function, like
most others, will accept a zero'd out struct.
This inches us closer to passing various tests in
"t34*.sh" (e.g. "t3434-rebase-i18n.sh"), but because they have so many
other memory leaks in revisions.c this doesn't make any test file or
even a single test pass.

Restructure code that's mostly added in 9055e401dd (sequencer:
introduce new commands to reset the revision, 2018-04-25) to avoid
code duplication, and to make freeing other resources easier in a
subsequent commit.
It's safe to initialize "tree_desc" to be zero'd out in order to
unconditionally free desc.buffer, it won't be initialized on the first
couple of "goto"'s.
There are three earlier "return"'s in this function which should
probably be made to use this new "cleanup" too, per [1] it looks like
they're leaving behind stale locks. But let's not try to fix every
potential bug here now, I'm just trying to narrowly plug a memory
leak.

Fix two different but related memory leaks in
verify_clean_subdirectory(). We leaked both the "pathbuf" if
read_directory() returned non-zero, and we never cleaned up our own
"struct dir_struct" either.
* "pathbuf": When the read_directory() call followed by the
free(pathbuf) was added in c81935348b (Fix switching to a branch
with D/F when current branch has file D., 2007-03-15) we didn't
bother to free() before we called die().
But when this code was later libified in 203a2fe117 (Allow callers
of unpack_trees() to handle failure, 2008-02-07) we started to leak
as we returned data to the caller. This fixes that memory leak,
which can be observed under SANITIZE=leak with e.g. the
"t1001-read-tree-m-2way.sh" test.
* "struct dir_struct": We've leaked the dir_struct ever since this
code was added back in c81935348b.
When that commit was written there wasn't an equivalent of
dir_clear(). Since it was added in 270be81604 (dir.c: provide
clear_directory() for reclaiming dir_struct memory, 2013-01-06)
we've omitted freeing the memory allocated here.
This memory leak could also be observed under SANITIZE=leak and the
"t1001-read-tree-m-2way.sh" test.
This makes all the test in "t1001-read-tree-m-2way.sh" pass under
"GIT_TEST_PASSING_SANITIZE_LEAK=true", we'd previously die in tests
25, 26 & 28.

There was only one user of the API left in remote-curl.c. I don't know
why I didn't include this change to remote-curl.c in
bc40dfb10a (string-list.h users: change to use *_{nodup,dup}(),
2021-07-01), perhaps I just missed it.
In any case, let's change that one user to use the new API, as of
writing this there are no in-flight changes that use, so this seems
like a good time to drop this before we get any new users of this
compatibility API.
