This just matches the style/location of the package installation for
other jobs. There should be no functional change.
I did flip the order of the options and command-name ("-y update"
instead of "update -y") for consistency with other lines in the same
file.
Note also that we have to reorder the dependency install with the
"checkout" action, so that we actually have the "ci" scripts available.

The "sparse" workflow runs "apt-get install" to pick up a few necessary
packages. But it needs to run "apt-get update" first, or it risks trying
to download an old package version that no longer exists. And in fact
this happens now, with output like:
2021-07-26T17:40:51.2551880Z E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/c/curl/libcurl4-openssl-dev_7.68.0-1ubuntu2.5_amd64.deb 404 Not Found [IP: 52.147.219.192 80]
2021-07-26T17:40:51.2554304Z E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
Our other ci jobs don't suffer from this; they rely on scripts in ci/,
and ci/install-dependencies does the appropriate "apt-get update".

The code that eventually became filter_bitmap_exclude_type() was
originally introduced in 4f3bd5606a (pack-bitmap: implement BLOB_NONE
filtering, 2020-02-14) to accelerate BLOB_NONE filters with bitmaps.
In 856e12c18a (pack-bitmap.c: make object filtering functions generic,
2020-05-04), it became filter_bitmap_exclude_type(). But not all of the
comments were updated to be agnostic to the provided type.
Remove the remaining comments which should have been updated in
856e12c18a to reflect the type-agnostic nature of the function.

Testcases in t0000 are quite special given that they many of them run
nested testcases to verify that testing functionality itself works as
expected. These nested testcases are realized by writing a new ad-hoc
test script which again sources test-lib.sh, where the new script is
created in a nested subdirectory located beneath the current trash
directory. We then execute the new test script with the nested
subdirectory as current working directory and explicitly re-export
TEST_OUTPUT_DIRECTORY to point to that directory.
While this works as expected in the general case, it falls apart when
the developer has TEST_OUTPUT_DIRECTORY explicitly defined either via
the environment or via config.mak and runs "make test". In that case,
test-lib.sh will clobber the value that we've just carefully set up to
instead contain what the developer has defined. As a result, the
TEST_OUTPUT_DIRECTORY continues to point at the root output directory,
not at the nested one.
This issue causes breakage in the 'test_atexit is run' test case: the
nested test case writes files into "../../", which is assumed to be the
parent's trash directory. But because TEST_OUTPUT_DIRECTORY already
points to to the root output directory, we instead end up writing those
files outside of the output directory. The parent test case will then
try to check whether those files still exist in its own trash directory,
which thus must fail now.
Fix the issue by adding a new TEST_OUTPUT_DIRECTORY_OVERRIDE variable.
If set, then we'll always override the TEST_OUTPUT_DIRECTORY with its
value after sourcing GIT-BUILD-OPTIONS.

Since cd57bc41bb (builtin/multi-pack-index.c: display usage on
unrecognized command, 2021-03-30) we have used a "usage" label to avoid
having two separate callers of usage_with_options (one when no arguments
are given, and another for unrecognized sub-commands).
But the first caller has been broken since cd57bc41bb, since it will
happily jump to usage without arguments, and then pass argv[0] to the
"unrecognized subcommand" error.
Many compilers will save us from a segfault here, but the end result is
ugly, since it mentions an unrecognized subcommand when we didn't even
pass one, and (on GCC) includes "(null)" in its output.
Move the "usage" label down past the error about unrecognized
subcommands so that it is only triggered when it should be. While we're
at it, bulk up our test coverage in this area, too.

In t0000, we run several fake "sub-test" suites to verify the behavior
of the test suite. But because we don't clear the parent environment
completely, the sub-tests can be fooled by variables meant for the
parent. For example:
GIT_SKIP_TESTS=t1234 ./t0000-basic.sh
fails when a sub-test expects its fake t1234 to actually run. This
particular pattern is unlikely in practice; we're running a single
script, and there is no t1234 in the real test suite anyway (not yet, at
least). A more real-world example is:
GIT_SKIP_TESTS=t[^0]* make test
to run only the t0* tests.
The fix is conceptually simple: we should clear the GIT_SKIP_TESTS
variable when running the sub-tests, because its contents (if any) will
be meant for the main test suite. This is easy to do centrally in our
sub-test helper.
But there's a catch: some of our tests do set GIT_SKIP_TESTS
intentionally to test the feature. We need to allow them to continue to
set it, but clear it for all the other tests. And the sub-test helper
can't tell if the GIT_SKIP_TESTS it sees is from a test or not. We can
handle this by adding a new option to the helper to let callers specify
the skip list.
I considered adding a more general "--eval" option to let callers set up
the env for the sub-test however they like. That would cover this case
and possible future ones. But the quoting gets awkward for the callers
(since we're now 2 layers deep in evals!), so I went with the simpler
more specific solution.

The shell+perl "[de]packetize()" helper functions were added in
4414a150025 (t/lib-git-daemon: add network-protocol helpers,
2018-01-24), and around the same time we added the "pkt-line" helper
in 74e70029615 (test-pkt-line: introduce a packet-line test helper,
2018-03-14).
For some reason it seems we've mostly used the shell+perl version
instead of the helper since then. There were discussions around
88124ab2636 (test-lib-functions: make packetize() more efficient,
2020-03-27) and cacae4329fa (test-lib-functions: simplify packetize()
stdin code, 2020-03-29) to improve them and make them more efficient.
There was one good reason to do so, we needed an equivalent of
"test-tool pkt-line pack", but that command wasn't capable of handling
input with "\n" (a feature) or "\0" (just because it happens to be
printf-based under the hood).
Let's add a "pkt-line-raw" helper for that, and expose is at a
packetize_raw() to go with the existing packetize() on the shell
level, this gives us the smallest amount of change to the tests
themselves.
