Stress test the parsing logic shared by fsck.skipList and
{fetch,receive}.fsck.skipList added in cd94c6f91e ("fsck: git
receive-pack: support excluding objects from fsck'ing",
2015-06-22). There were no tests for the work done by the
init_skiplist() routine, e.g. how it dies on invalid input.

Test and document that the {fetch,receive}.fsck.* family of variables
doesn't fall back on the corresponding .fsck.* variables.
This was alluded to in the existing documentation by saying that
"receive" looks at receive.fsck.* and "fsck" looks at fsck.* etc., but
it wasn't explicitly stated that there was no fallback, and if you'd
e.g. like to configure the skipList you need to do that for all three.

Implement support for fetch.fsck.* corresponding with the existing
receive.fsck.*. This allows for pedantically cloning repositories with
specific issues without turning off fetch.fsckObjects.
One such repository is https://github.com/robbyrussell/oh-my-zsh.git
which before this change will emit this error when cloned with
fetch.fsckObjects:
error: object 2b7227859263b6aabcc28355b0b994995b7148b6: zeroPaddedFilemode: contains zero-padded file modes
fatal: Error in object
fatal: index-pack failed
Now with fetch.fsck.zeroPaddedFilemode=warn we'll warn about that
issue, but the clone will succeed:
warning: object 2b7227859263b6aabcc28355b0b994995b7148b6: zeroPaddedFilemode: contains zero-padded file modes
warning: object a18c4d13c2a5fa2d4ecd5346c50e119b999b807d: zeroPaddedFilemode: contains zero-padded file modes
warning: object 84df066176c8da3fd59b13731a86d90f4f1e5c9d: zeroPaddedFilemode: contains zero-padded file modes
The motivation for this is to be able to turn on fetch.fsckObjects
globally across a fleet of computers but still be able to manually
clone various legacy repositories by either white-listing specific
issues, or better yet whitelist specific objects.
The use of --git-dir=* instead of -C in the tests could be considered
somewhat archaic, but the tests I'm adding here are duplicating the
corresponding receive.* tests with as few changes as possible.

The tests for transfer.fsckObjects have grown organically over time to
not make much sense.
Initially when these were added in b10a53583f ("test: fetch/receive
with fsckobjects", 2011-09-04) they were only testing the "corrupt or
missing object" case, but later on in 70a4ae73d8 ("fsck: add a simple
test for receive.fsck.<msg-id>", 2015-06-22) they were expanded to
check for the fsck.<msg-id> feature.
The problem was that we still kept the same corrupt test repo, making
it harder to add new tests that check the entirety of the repository
between operations via "git fsck" to see whether only known issues
that can be ignored with fsck.<msg-id> have occurred.
The tests only did the right thing because such a full "git fsck" was
never done after a certain point, and instead we were only
manipulating specific refs. This makes it harder to add new tests, and
none of the fsck.<msg-id> tests relied on this.
So let's not confuse the two and repair the corrupt repository before
we run the fsck.<msg-id> tests.

Change the transfer.fsckObjects documentation to explicitly note the
unique security and/or corruption issues fetch.fsckObjects suffers
from, since it doesn't have a quarantine environment.
This was already alluded to in the existing documentation, but let's
spell it out so there's no confusion here, and give a concrete example
of how to work around this limitation.
Let's also prominently note that this is considered to be a limitation
of the current implementation, rather than something that's intended
and by design, since we might change this in the future.

The existing documentation led the user to believe that all we were
doing were basic reachability sanity checks, but that hasn't been true
for a very long time. Update the description to match reality, and
note the caveat that there's a quarantine for accepting pushes, but
not for fetching.
Also mention that the fsck checks for security issues, which was my
initial motivation for writing this fetch.fsck.* series.

The documentation for the fsck.<msg-id> and receive.fsck.<msg-id>
variables was mostly duplicated in two places, with fsck.<msg-id>
making no mention of the corresponding receive.fsck.<msg-id>, and the
same for fsck.skipList.
I spent quite a lot of time today wondering why setting the
fsck.<msg-id> variant wasn't working to clone a legacy repository (not
that that would have worked anyway, but a subsequent patch implements
fetch.fsck.<msg-id>).
Rectify this situation by describing the feature in general terms
under the fsck.* documentation, and make the receive.fsck.*
documentation refer to those variables instead.
This documentation was initially added in 2becf00ff7 ("fsck: support
demoting errors to warnings", 2015-06-22) and 4b55b9b479 ("fsck:
document the new receive.fsck.<msg-id> options", 2015-06-22).

Refer readers of fetch.fsckObjects and receive.fsckObjects to
transfer.fsckObjects instead of repeating the description at each
location.
I don't think this description of them makes much sense, but for now
I'm just moving the existing documentation around. Making it better
will be done in a later patch.

Remove the setting of a receive.fsck.badDate config variable to
"ignore". This was added in efaba7cc77 ("fsck: optionally ignore
specific fsck issues completely", 2015-06-22) but never did anything,
presumably it was part of some work-in-progress code that never made
it into git.git.
None of these tests will emit the "invalid author/committer line - bad
date" warning. The dates on the commit objects we're setting up are
not invalid.
