Reduce the allocations done by show_ambiguous_object() by moving the
"desc" strbuf into the "struct ambiguous_output" introduced in the
preceding commit.
This doesn't matter for optimization purposes, but since we're
accumulating a "struct strbuf advice" anyway let's follow that pattern
and add a "struct strbuf sb", we can then strbuf_reset() it rather
than calling strbuf_release() for each call to
show_ambiguous_object().

Change the "The candidates are" header that's shown for ambiguous
objects to be shown after we've iterated over all of the objects.
If we get any errors while doing so we don't want to split up the the
header and the list as a result. The two will now be printed together,
as shown in the updated testcase.
As we're accumulating the lines into as "struct strbuf" before
emitting them we need to add a trailing newline to the call in
show_ambiguous_object(). This and the change from "The candidates
are:" to "The candidates are:\n%s" helps to give translators more
context.

Make the ambiguous tag object output nicer in the case of tag objects
such as ebf3c04b262 (Git 2.32, 2021-06-06) by including the date in
the "tagger" header. I.e.:
$ git rev-parse b7e68
error: short object ID b7e68 is ambiguous
hint: The candidates are:
hint: b7e68c41d92 tag 2021-06-06 - v2.32.0
hint: b7e68ae18e0 commit 2019-12-23 - bisect: use the standard 'if (!var)' way to check for 0
hint: b7e68f6b413 tree
hint: b7e68490b97 blob
b7e68
[...]
Before this we'd emit a "tag" line without a date, e.g.:
hint: b7e68c41d92 tag v2.32.0

Change the output of show_ambiguous_object() added in [1] and last
tweaked in [2] and the preceding commit to be more friendly to
translators.
By being able to customize the "<SP><SP>%s\n" format we're even ready
for RTL languages, who'd presumably like to change that to
"%s<SP><SP>\n".
In the case of the existing "tag [tag could not be parsed]" output
we'll now instead emit "[bad tag, could not parse it]". This is
consistent with the "[bad object]" output. Rephrasing the message like
this is possible because we're not unconditionally adding the
type_name() at the beginning.

Follow-up the handling of OBJ_BAD in the preceding commit and
explicitly handle those cases where parse_tag() fails, or we don't end
up with a non-NULL pointer in in tag->tag.
If we run into such a tag we'd previously be silent about it. We
really should also be handling these batter in parse_tag_buffer() by
being more eager to emit an error(), instead of silently aborting with
"return -1;".
One example of such a tag is the one that's tested for in
"t3800-mktag.sh", where the code takes the "size <
the_hash_algo->hexsz + 24" branch.
But in lieu of earlier missing "error" output let's show the user
something to indicate why we're not showing a tag message in these
cases, now instead of showing:
hint: deadbeef tag
We'll instead display:
hint: deadbeef tag [tag could not be parsed]

Amend the "unknown type" handling in the code that displays the
ambiguous object list to assert() that we're either going to get the
"real" object types we can pass to type_name(), or a -1 (OBJ_BAD)
return value from oid_object_info().
See [1] for the current output, and [1] for the commit that added the
"unknown type" handling.
We are never going to get an "unknown type" in the sense of custom
types crafted with "hash-object --literally", since we're not using
the OBJECT_INFO_ALLOW_UNKNOWN_TYPE flag.
If we manage to otherwise unpack such an object without errors we'll
die() in parse_loose_header_extended() called by sort_ambiguous()
before we get to show_ambiguous_object(), as is asserted by the test
added in the preceding commit.
So saying "unknown type" here was always misleading, we really meant
to say that we had a failure parsing the object at all, i.e. that we
had repository corruption. If the problem is only that it's type is
unknown we won't reach this code.
So let's emit a generic "[bad object]" instead. As our tests added in
the preceding commit show, we'll have emitted various "error" output
already in those cases.
We should do better in the truly "unknown type" cases, which we'd need
to handle if we were passing down the OBJECT_INFO_ALLOW_UNKNOWN_TYPE
flag. But let's leave that for some future improvement. In a
subsequent commit I'll improve the output we do show, and not having
to handle the "unknown type" (as in OBJECT_INFO_ALLOW_UNKNOWN_TYPE)
simplifies that change.

Extend the tests for ambiguous objects to check how we handle objects
where we return OBJ_BAD when trying to parse them. As noted in [1] we
have a blindspot when it comes to this behavior.
Since we need to add new test data here let's extend these tests to be
tested under SHA-256, in d7a2fc82491 (t1512: skip test if not using
SHA-1, 2018-05-13) all of the existing tests were skipped, as they
rely on specific SHA-1 object IDs.
For these tests it only matters that the first 4 characters of the OID
prefix are the same for both SHA-1 and SHA-256. This uses strings that
I mined, and have the same prefix when hashed with both.
We "test_cmp" the full output to guard against any future regressions,
and because a subsequent commit will tweak it. Showing a diff of how
the output changes is helpful to explain those subsequent commits.
The "sed" invocation in test_cmp_failed_rev_parse() doesn't need a
"/g" because under both SHA-1 and SHA-256 we'll wildcard match any
trailing part of the OID after our known starting prefix. We'd like to
convert all of that to just "..." for the "test_cmp" which follows.

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.

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).
