Change a pattern of hardcoding an "argv" array size, populating it and
assigning to the "argv" member of "struct child_process" to instead
use "strvec_pushl()" to add data to the "args" member.
This implements the same behavior as before in fewer lines of code,
and moves us further towards being able to remove the "argv" member in
a subsequent commit.
Since we've entirely removed the "argv" variable(s) we can be sure
that no potential logic errors of the type discussed in a preceding
commit are being introduced here, i.e. ones where the local "argv" was
being modified after the assignment to "struct child_process"'s
"argv".

As in the preceding commit change this API user to use strvec_pushv()
instead of assigning to the "argv" member directly. This leaves us
without test coverage of how the "argv" assignment in this API works,
but we'll be removing it in a subsequent commit.

Migrate those run-command API users that assign directly to the "argv"
member to use a strvec_pushv() of "args" instead.
In these cases it did not make sense to further refactor these
callers, e.g. daemon.c could be made to construct the arguments closer
to handle(), but that would require moving the construction from its
cmd_main() and pass "argv" through two intermediate functions.
It would be possible for a change like this to introduce a regression
if we were doing:
cp.argv = argv;
argv[1] = "foo";
And changed the code, as is being done here, to:
strvec_pushv(&cp.args, argv);
argv[1] = "foo";
But as viewing this change with the "-W" flag reveals none of these
functions modify variable that's being pushed afterwards in a way that
would introduce such a logic error.

This pattern added [1] in seems to have been intentional, but since
[2] and [3] we've wanted do initialization of what's now the "struct
strvec" "args" and "env_array" members. Let's not trample on that
initialization here.

add_worktree() reuses a `child_process` for three run_command()
invocations, but to do so, it has overly-intimate knowledge of
run-command.c internals. In particular, it knows that it must reset
child_process::argv to NULL for each subsequent invocation[*] in order
for start_command() to latch the newly-populated child_process::args for
each invocation, even though this behavior is not a part of the
documented API. Beyond having overly-intimate knowledge of run-command.c
internals, the reuse of one `child_process` for three run_command()
invocations smells like an unnecessary micro-optimization. Therefore,
stop sharing one `child_process` and instead use a new one for each
run_command() call.
[*] If child_process::argv is not reset to NULL, then subsequent
run_command() invocations will instead incorrectly access a dangling
pointer to freed memory which had been allocated by child_process::args
on the previous run. This is due to the following code in
start_command():
if (!cmd->argv)
cmd->argv = cmd->args.v;

This reverts commit f6526728f950cacfd5b5e42bcc65f2c47f3da654.
The change in f652672 (dir: select directories correctly, 2021-09-24)
caused a regression in directory-based matches with non-cone-mode
patterns, especially for .gitignore patterns. A test is included to
prevent this regression in the future.
The commit ed495847 (dir: fix pattern matching on dirs, 2021-09-24) was
reverted in 5ceb663 (dir: fix directory-matching bug, 2021-11-02) for
similar reasons. Neither commit changed tests, and tests added later in
the series continue to pass when these commits are reverted.

While at it, format the URL for a GitHub user's workflow runs of Git

When checking typos in file "po/ko.po", "git-po-helper" reports lots of

these false positives, some easy-to-fix typos are found and fixed.

In the preceding commit a free() of uninitialized memory regression in
96e41f58fe1 (fsck: report invalid object type-path combinations,
2021-10-01) was fixed, but we'd still have an issue with leaking
memory from fsck_loose(). Let's fix that issue too.
That issue was introduced in my 31deb28f5e0 (fsck: don't hard die on
invalid object types, 2021-10-01). It can be reproduced under
SANITIZE=leak with the test I added in 093fffdfbec (fsck tests: add
test for fsck-ing an unknown type, 2021-10-01):
./t1450-fsck.sh --run=84 -vixd
In some sense it's not a problem, we lost the same amount of memory in
terms of things malloc'd and not free'd. It just moved from the "still
reachable" to "definitely lost" column in valgrind(1) nomenclature[1],
since we'd have die()'d before.
But now that we don't hard die() anymore in the library let's properly
free() it. Doing so makes this code much easier to follow, since we'll
now have one function owning the freeing of the "contents" variable,
not two.
For context on that memory management pattern the read_loose_object()
function was added in f6371f92104 (sha1_file: add read_loose_object()
function, 2017-01-13) and subsequently used in c68b489e564 (fsck:
parse loose object paths directly, 2017-01-13). The pattern of it
being the task of both sides to free() the memory has been there in
this form since its inception.

This reverts commit f45022dc2fd692fd024f2eb41a86a66f19013d43,
as this is like breakage in the traversal more likely. In a
history with 10 single strand of pearls,
1-->2-->3--...->7-->8-->9-->10
asking "rev-list --unsorted-input 1 10 --not 9 8 7 6 5 4" fails to
paint the bottom 1 uninteresting as the traversal stops, without
completing the propagation of uninteresting bit starting at 4 down
through 3 and 2 to 1.

Fix a regression introduced in my 96e41f58fe1 (fsck: report invalid
object type-path combinations, 2021-10-01). When fsck-ing blobs larger
than core.bigFileThreshold, we'd free() a pointer to uninitialized
memory.
This issue would have been caught by SANITIZE=address, but since it
involves core.bigFileThreshold, none of the existing tests in our test
suite covered it.
Running them with the "big_file_threshold" in "environment.c" changed
to say "6" would have shown this failure, but let's add a dedicated
test for this scenario based on Han Xin's report[1].
The bug was introduced between v9 and v10[2] of the fsck series merged
in 061a21d36d8 (Merge branch 'ab/fsck-unexpected-type', 2021-10-25).
