Pass through the parser the ids of blobs identified as .gitmodules
files in the ObjectChecker. Load the blobs and parse/validate them

ObjectChecker: Report .gitmodules files found in the pack
In order to validate .gitmodules files, we first need to find them
in the incoming pack.
Do it in the ObjectChecker stage. Check in the tree objects if they
point to a .gitmodules file and report the tree id and the .gitmodules
blob id.
This can be used later to check if the file is in the root of the
project and if the contents are good.
While we're here, make isMacHFSGit more accurate by detecting variants
of filenames that vary in case.
[jn: tweaked NTFS and HFS+ checking; added more tests]

SubmoduleAddCommand: Reject submodule URIs that look like cli options
In C git versions before 2.19.1, the submodule is fetched by running
"git clone <uri> <path>". A URI starting with "-" would be interpreted
as an option, causing security problems. See CVE-2018-17456.
Refuse to add submodules with URIs, names or paths starting with "-",
that could be confused with command line arguments.

This test was never being run. Since it was introduced it was
named "notest.." which meant it didn't run with JUnit3, and
since it is not annotated @Test it also doesn't run with JUnit4.
When compiling with Bazel 0.6.0, error-prone raises an error
that the public method is not annotated with @Ignore or @Test.
Given that the test has never been run anyway, we can just
remove it.

After packaging references, the folders containing these references are
not deleted. In a busy repository, this causes operations to slow down
as traversing the references tree becomes longer.
Delete empty reference folders after the loose references have been
packed.
To avoid deleting a folder that was just created by another concurrent
operation, only delete folders that were not modified in the last 30
seconds.

Fix exception handling for opening bitmap index files
When creating a new PackFile instance it is specified whether this pack
has an associated bitmap index file or not. This information is cached
and the public method getBitmapIndex() will always assume a bitmap index
file must exist if the cached data tells so. But it may happen that the
packfiles are repacked during a gc in a different process causing the
packfile, bitmap-index and index file to be deleted. Since JGit still
has an open FileHandle on the packfile this file is not really deleted
and can still be accessed. But index and bitmap index file are deleted.
Fix getBitmapIndex() to invalidate the cached packfile instance if such
a situation occurs.
This problem showed up when a gerrit server was serving repositories
which where garbage collected with native git regularly. Fetch and
clone commands for certain repositories failed permanently after a
native git gc had deleted old bitmap index files.

Fix null return from FS.readPipe when command fails to launch
When a command invoked from readPipe fails to launch (i.e. the exec call
fails due to a missing command executable), Process.start() throws,
which gets caught by the generic IOException handler, resulting in a
null return. This change detects this case and rethrows a
CommandFailedException instead.
Additionally, this change uses /bin/sh instead of bash for its posix
command failure test, to accomodate building in environments where bash
is unavailable.

Commit db77610 ensured that all refs/tags commits are added to the
primary GC pack. It did that by adding all of the refs/tags commits
to the primary GC pack PackWriter's "interesting" object set.
Unfortunately, all commit objects in the "interesting" set are
selected as commits for which bitmap indices will be built. In a
repository like chromium with lots of tags, this changed the number of
bitmaps created from <700 to >10000. That puts huge memory pressure on
the GC task.
This change restores the original behavior of ignoring tags when
selecting commits for bitmaps.
In the "uninteresting" set, commits for refs/heads and refs/tags for
unannotated tags can not be differentiated. We instead identify
refs/tags commits by passing their ObjectIds as a new "noBitmaps"
parameter to the PackWriter.preparePack() methods.
PackWriterBitmapPreparer.setupTipCommitBitmaps() can then use that
"noBitmaps" parameter to exclude those commits.

Delete expired garbage even when there is no GC pack present.
Delete the condition to check whether the garbage pack creation time
is older than the last GC operation, because it's not possible to
find the last GC operation time when there is no GC pack.
Add additional tests to make sure the contents of the expired garbage
packs are considered during the GC operation and any actively
referenced objects from the garbage packs are copied successfully
into the GC pack before deleting the garbage pack.

Android wants them to work, and we're only interested in them for bare
repos, so add them just for that.
Make sure to use symlinks instead of just using the copyfile
implementation. Some scripts look up where they're actually located in
order to find related files, so they need the link back to their
project.

This is necessary for deploying submodules on android.googlesource.com.
* Allow an empty base URL. This is useful if the 'fetch' field is "."
and all names are relative to some host root.
* The URLs in the resulting superproject are relative to the
superproject's URL. Add RepoCommand#setDestinationURI to
set this. If unset, the existing behavior is maintained.
* Add two tests for the Android and Gerrit case, checking the URL
format in .gitmodules; the tests use a custom RemoteReader which is
representative of the use of this class in Gerrit's Supermanifest
plugin.
