Git has different conflict resolution strategies:
* There is a tree merge strategy "ours" which just ignores any changes
from theirs ("-s ours"). JGit also has the mirror strategy "theirs"
ignoring any changes from "ours". (This doesn't exist in C git.)
Adapt StashApplyCommand and CherrypickCommand to be able to use those
tree merge strategies.
* For the resolve/recursive tree merge strategies, there are content
conflict resolution strategies "ours" and "theirs", which resolve
any conflict hunks by taking the "ours" or "theirs" hunk. In C git
those correspond to "-Xours" or -Xtheirs". Implement that in
MergeAlgorithm, and add API to set and pass through such a strategy
for resolving content conflicts.
* The "ours/theirs" content conflict resolution strategies also apply
for binary files. Handle these cases in ResolveMerger.
Note that the content conflict resolution strategies ("-X ours/theirs")
do _not_ apply to modify/delete or delete/modify conflicts. Such
conflicts are always reported as conflicts by C git. They do apply,
however, if one side completely clears a file's content.

init: add config option to set default for the initial branch name
We introduced the option --initial-branch=<branch-name> to allow
initializing a new repository with a different initial branch.
To allow users to override the initial branch name more permanently
(i.e. without having to specify the name manually for each 'git init'),
introduce the 'init.defaultBranch' option.
This option was added to git in 2.28.0.

Add a GpgSignatureVerifier interface, plus a factory to create
instances thereof that is provided via the ServiceLoader mechanism.
Implement the new interface for BouncyCastle. A verifier maintains
an internal LRU cache of previously found public keys to speed up
verifying multiple objects (tag or commits). Mergetags are not handled.
Provide a new VerifySignatureCommand in org.eclipse.jgit.api together
with a factory method Git.verifySignature(). The command can verify
signatures on tags or commits, and can be limited to accept only tags
or commits. Provide a new public WrongObjectTypeException thrown when
the command is limited to either tags or commits and a name resolves
to some other object kind.
In jgit.pgm, implement "git tag -v", "git log --show-signature", and
"git show --show-signature". The output is similar to command-line
gpg invoked via git, but not identical. In particular, lines are not
prefixed by "gpg:" but by "bc:".
Trust levels for public keys are read from the keys' trust packets,
not from GPG's internal trust database. A trust packet may or may
not be set. Command-line GPG produces more warning lines depending
on the trust level, warning about keys with a trust level below
"full".
There are no unit tests because JGit still doesn't have any setup to
do signing unit tests; this would require at least a faked .gpg
directory with pre-created key rings and keys, and a way to make the
BouncyCastle classes use that directory instead of the default. See
bug 547538 and also bug 544847.
Tested manually with a small test repository containing signed and
unsigned commits and tags, with signatures made with different keys
and made by command-line git using GPG 2.2.25 and by JGit using
BouncyCastle 1.65.

Add the two config constants from C git that can switch on signing
of annotated tags. Add them to the GpgConfig, and implement actually
signing a tag in TagCommand.
The interactions between command line options for "git tag" and config
options is a bit murky in C git. There are two config settings for it:
* tag.gpgSign is the main option, if set to true, it kicks in if
neither -s nor -u are given on the command line.
* tag.forceSignAnnotated signs only tags created via "git tag -m",
but only if command-line option "-a" is not present. It applies
even if tag.gpgSign is set explicitly to false.
Giving -s or -u on the command line also forces an annotated tag
since lightweight tags cannot be signed.

Fix "jgit checkout -f" to overwrite dirty worktree files
CheckoutCommand had a setForce() method. But this didn't correspond
to native git's 'git checkout -f' option. Deprecate the old setForce()
method and move its implementation to a new method setForceRefUpdate()
and use it to implement the -B option in the CLI class Checkout.
Add a setForced() method and use it to fix the associated '-f' option of
the CLI Checkout class to behave like native git's 'git checkout -f'
which overwrites dirty worktree files during checkout.
This is still not fully matching native git's behavior: updating
additionally dirty index entries is not done yet.

Enables using the new ssh client based on Apache MINA sshd instead
of the old JSch client. The default is still JSch, so unless the
command is invoked with --ssh apache, there's no change.
I prefer this over some fiddling with the GIT_SSH environment variable
since that variable is handled in the JGit core bundle, which should
remain free of any dependency to org.eclipse.jgit.ssh.apache to avoid
problems in Gerrit or other JGit users that may use a different Apache
MINA sshd version.

gc: Add options to preserve and prune old pack files
The new --preserve-oldpacks option moves old pack files into the
preserved subdirectory instead of deleting them after repacking.
The new --prune-preserved option prunes old pack files from the
preserved subdirectory after repacking, but before potentially
moving the latest old packfiles to this subdirectory.
These options are designed to prevent stale file handle exceptions
during git operations which can happen on users of NFS repos when
repacking is done on them. The strategy is to preserve old pack files
around until the next repack with the hopes that they will become
unreferenced by then and not cause any exceptions to running processes
when they are finally deleted (pruned).

Add a storage implementation storing large objects in Amazon S3.
The AmazonS3Repository pre-signs download and upload requests.
AWS access and secret key are expected to be in the
$HOME/.aws/credentials file in the following format:
[default]
accessKey = ...
secretKey = ...
Use AWS version 4 request signing [1] because it is more secure and
supported by all regions. The version 3 signing is not supported in
newer regions.
In follow up changes we should:
- implement getVerifyAction() and do actual verification. Subclasses of
S3Repository can implement caching for object meta data (size) in order
to avoid extra roundtrips to S3. Verification should ensure that meta
data store and content of S3 storage are in sync
- HEAD request used in S3Repository.getSize() seems to always return
Content-length 0 in contrast to the documentation [2]. So getSize() does
detect if the object exists in S3 or not but in case the object exists
it always returns size 0

Support LFS protocol and a file system based LFS storage
Implement LfsProtocolServlet handling the "Git LFS v1 Batch API"
protocol [1]. Add a simple file system based LFS content store and the
debug-lfs-store command to simplify testing.
Introduce a LargeFileRepository interface to enable additional storage
implementation while reusing the same protocol implementation.
At the client side we have to configure the lfs.url, specify that
we use the batch API and we don't use authentication:
[lfs]
url = http://host:port/lfs
batch = true
[lfs "http://host:port/lfs"]
access = none
the git-lfs client appends the "objects/batch" to the lfs.url.
Hard code an Authorization header in the FileLfsRepository.getAction
because then git-lfs client will skip asking for credentials. It will
just forward the Authorization header from the response to the
download/upload request.
The FileLfsServlet supports file content storage for "Large File
Storage" (LFS) server as defined by the Github LFS API [2].
- upload and download of large files is probably network bound hence use
an asynchronous servlet for good scalability
- simple object storage in file system with 2 level fan-out
- use LockFile to protect writing large objects against multiple
concurrent uploads of the same object
- to prevent corrupt uploads the uploaded file is rejected if its hash
doesn't match id given in URL
The debug-lfs-store command is used to run the LfsProtocolServlet and,
optionally, the FileLfsServlet which makes it easier to setup a
local test server.

Null-annotated Repository class and fixed related compiler errors
org.eclipse.jgit.lib.Repository class is an example of the API which
should be written with Java 8 java.util.Optional<T> type. Unfortunately
this API is already released and widely used. The good clients are
currently doing their best with checking return values for null and bad
clients do not know how bad their code is.
I've tried not to change any logic and to be as less intrusive as
possible. Most of the JGit code was well prepared to this, only few
classes needed some smaller fixes.
This change fixes all compiler errors in JGit and replaces possible
NPE's with either appropriate exceptions, avoiding multiple "Nullable
return" method calls or early returning from the method.
Because annotating getDirectory() and getFS() as Nullable would cause
lot of additional changes in JGit and EGit they are postponed.
