InMemoryRepository: Remove unused RevWalk from batch method signature
The RevWalk given in the arguments is not used. According to the
comment at the top of the method, a new RevWalk is intentionally
used in the implementation.
Remove the unused argument.

Attributes MacroExpander implements macros used in git attributes. This
is implemented inside the TreeWalk using a lazy created MacroExpander.
In addition, the macro expander caches the global and info attributes
node in order to provide fast merge of attributes.

Add option to allow empty commits to CommitCommand
CommitCommand should allow to specify whether empty commits (commits
having the same tree as the sole predecessor commit) are allowed or not.
Similar to native git's "--allow-empty" flag.
The defaults differ between JGit and native git even after this change.
When not specifying paths then by default JGit allows to create empty
commits while native git does not. It would be API breaking to change
this now.

Git Ketch is a multi-master Git repository management system. Writes
are successful only if a majority of participant servers agree. Acked
writes are durable against server failures as a majority of the
participants store all required objects.
Git Ketch is modeled on the Raft Consensus Algorithm[1]. A ketch
sailing vessel is faster and more nimble than a raft. It can also
carry more source codes.
Git Ketch front-loads replication costs, which vaguely resembles a
ketch sailing vessel's distinguishing feature of the main mast on the
front of the ship.

This could have only happened during the getBytes call. Instead, use
Constants.encode, which is a non-throwing implementation.
This change is binary compatible with existing code compiled against
older versions of JGit, although it might break compilation of
previously compiling code due to dead catch blocks.

RefTree: Change peel suffix to " ^" (space carrot)
Using ^{} as the peel suffix has caused problems when projects used
tags like v2.1 and then v2.1.1, v2.2.2, etc. The peeled value for
v2.1 was stored very far away in the tree relative to v2.1 itself as
^ sorts in the ASCII/UTF-8 encoding after all other common tag
characters like digits and dots.
Use " ^" instead as space is not valid in a reference name, sorts
before all other valid reference characters (thus forcing next entry
locality) and this looks like a peeled marker for the prior tag.

FileRepository: Support extensions.refsBackendType = RefTree

When these are set the repository will read references from the
RefTree rooted by the $GIT_DIR/refs/txn/committed reference.

the bootstrap layer. This avoids misuse by rebuilding using packed-refs

RefTreeDatabase: Ref database using refs/txn/committed
Instead of storing references in the local filesystem rely on the
RefTree rooted at refs/txn/committed. This avoids needing to store
references in the packed-refs file by keeping all data rooted under
a single refs/txn/committed ref.
Performance to scan all references from a well packed RefTree is very
close to reading the packed-refs file from local disk.
Storing a packed RefTree is smaller due to pack file compression,
about 49.39 bytes/ref (on average) compared to packed-refs using
~65.49 bytes/ref.

A group of updates can be applied by updating the tree in one step,
writing out a new root tree, and storing its SHA-1. If references
are stored in RefTrees, comparing two repositories is a matter of
checking if two SHA-1s are identical. Without RefTrees comparing two
repositories requires listing all references and comparing the sets.
Track the "refs/" directory as a root tree by storing references
that point directly at an object as a GITLINK entry in the tree.
For example "refs/heads/master" is written as "heads/master".
Annotated tags also store their peeled value with ^{} suffix, using
"tags/v1.0" and "tags/v1.0^{}" GITLINK entries.
Symbolic references are written as SYMLINK entries with the blob of
the symlink carrying the name of the symbolic reference target.
HEAD is outside of "refs/" namespace so it is stored as a special
"..HEAD" entry. This name is chosen because ".." is not valid in
a reference name and it almost looks like "../HEAD" which names
HEAD if the reader was inside of the "refs/" directory.
A new Command type is required to handle symbolic references and
peeled references.

Accept some of the same section keys that fsck does in git-core,
allowing repositories to skip over specific kinds of acceptable
broken objects, e.g.:
[fsck]
duplicateEntries = ignore
zeroPaddedFilemode = ignore
The zeroPaddedFilemode = ignore is a synonym for the JGit specific
allowLeadingZeroFileMode = true. Only accept the JGit key if git-core
key was not specified.

Some ancient objects may be broken, but in a relatively harmless way.
Allow the ObjectChecker caller to whitelist specific objects that are
going to fail checks, but that have been reviewed by a human and decided
the objects are OK enough to permit continued use of.
This avoids needing to rewrite history to scrub the broken objects out.
Honor the git-core fsck.skipList configuration setting when receiving a
push or fetching from a remote repository.
