The main concern are submodule urls starting with '-' that could pass as
options to an unguarded tool.
Pass through the parser the ids of blobs identified as .gitmodules
files in the ObjectChecker. Load the blobs and parse/validate them
in SubmoduleValidator.

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.

Revert "Configure WindowCache settings to use in JGit CLI"
This reverts commit e6375445d1.
Hard coding WindowCache settings wasn't a good idea, this prevents that
custom settings can be configured. Also using virtual memory mapping has
issues on Windows.

ConfigTest: Fix tests for getting empty config value as int
The tests were set up to expect an IllegalArgumentException when
the Config.getInt method was called with a section.key that has
not been set, or explicitly set to an empty string.
However, the IllegalArgumentException never gets thrown because
the getInt method returns the provided default ("1"), and because
there was no call to "fail" after getInt, the incorrect behavior
of the test was not noticed.
Remove the try/catch around getInt, and instead assert that the
expected default value is returned.

Support the deepen-since parameter when requested by a client using
protocol v2. This is done by:
- adding a DepthWalk.RevWalk#setDeepenSince method
- updating DepthGenerator to recognize when deepen-since is set
- recording in DepthWalk.Commit whether a commit is a boundary commit
Existing users of DepthWalk such as UploadPack previously recognized
boundary commits by comparing their depths against the threshold, not
tracking whether any parents were truly excluded. This behavior is
preserved - UploadPack considers a commit as boundary if its depth is
equal to the threshold *or* a parent was excluded (whether by depth or
by deepen-since).

In DepthGenerator, commits are always added to the "pending" queue
either at depth 0 (in the constructor) or after a depth check (in
next()), so it is redundant to check for depth after removing them from
the queue. Remove the check.
This redundancy seems to have been present since the introduction of
server-side shallow clone support in commit 9952223e06 ("Implement
server support for shallow clones", 2011-08-21).

FileRepositoryBuilderTest: Don't explicitly close BufferedWriter in try-with-resource
The BufferedWriter is opened in a try-with-resource and thus will be
automatically closed.
Presumably the close was added to make sure it is closed before the
subsequent test statements are executed. Instead of explicitly closing
it, let the try-with-resource automatically close it, and move the
subsequent statements out of the try-block.
