AdvertiseRefsHook is used to limit the visibility of the refs in Gerrit.
If this hook is not called, then all refs are treated as visible,
causing the server to serve commits reachable from branches the client
should not be able to access, if asked to via a request naming a guessed
object id.
Until 3a529361a76e8267467071e0b13ebb36b97d8fb2 (Call AdvertiseRefsHook
before validating wants, 2018-12-18), UploadPack would invoke this hook
at ref advertisement time but not during negotiation and when serving a
pack file. Add a test to avoid regressing. Stateful bidirectional
transports were not affected, so the test uses HTTP.
[jn: split out when backporting the fix to stable-4.5. The test passes
as long as v4.9.0.201710071750-r~169 (fetch: Accept any SHA-1 on lhs of
refspec, 2017-06-04) is cherry picked along with it.]

AdvertiseRefsHook is used to limit the visibility of the refs in Gerrit.
If this hook is not called, then all refs are treated as visible,
causing the server to serve commits reachable from branches the client
should not be able to access, if asked to via a request naming a guessed
object id.
This bug was introduced in v2.0.0.201206130900-r~123 (Modify refs in
UploadPack/ReceivePack using a hook interface, 2012-02-08). Stateful
bidirectional transports are not affected.
Fix it by moving the AdvertiseRefsHook call to
getAdvertisedOrDefaultRefs, ensuring the hook is called in all cases.
[jn: backported to stable-4.5 by splitting out tests and the protocol v2
specific parts]

SpotBugs [1] is the spiritual successor of FindBugs, carrying on from
the point where it left off with support of its community.
This is a backport of [1] which originally did the replacement on the
master branch. This change updates to the current latest version, so
that we can get the benefit of its checks when pushing changes to the
stable branches.

A .gitmodules file can include a submodule without a path to configure
the URL for a submodule that is only present on other branches.
A .gitmodules file can include a submodule with no URL and no path to
reserve the name for a submodule that existed in earlier history but
is not available from any URL any more.
"git fsck" permits both of these cases. Permit them in JGit as well
(instead of throwing NullPointerException).

The text "<tree, blob>" with angle brackets should not be used in javadoc
since it is interpreted as an HTML tag and then rejected since it's not a
valid HTML tag. Wrap the text in a @literal tag.
Also add a missing space.

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.

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]

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.

dotdot check code in v5.1.0.201808281540-m3~57 (Add API to specify
