* changes:
daemon: Add --ketch=LEADER flag
Ketch: Intercept push and route it through Ketch
Ketch: Simple map of running leader instances
Ketch: Basic replication system
This form of addTree() does not parse any objects and cannot throw the
declared checked exception. Callers are being forced to try-catch
CorruptObjectException that cannot occur when the iterator instance
has already been constructed.

ResetCommand was not returning the updated ref as a result of the call()
method. Since the ResetCommand is always updating the same ref (HEAD)
this should always be the HEAD ref.

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.

Experimental flag to turn on the KetchLeader within this daemon JVM.
This is a manually elected leader process, set from the command line.
Remote followers for each repository are configured per-repository
using remote sections with ketch-type = FULL. For example:
Manually elected leader's $GIT_DIR/config:
[ketch]
name = A
[remote "A"]
ketch-type = FULL
[remote "B"]
url = git://127.0.0.1:9421/sample.git
ketch-type = FULL
[remote "C"]
url = git://127.0.0.1:9422/sample.git
ketch-type = FULL
Replica B and C daemons:
git daemon \
--export-all \
--enable=receive-pack \
--listen=127.0.0.1 --port=9421 \
--base-path=$HOME/ketch_test/follower_one \

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.

After creating a Transport instance callers should always call
its close() method. Use AutoCloseable to document this idiom
and allow use of try-with-resources.

If one or more commands is failing the entire group usually has to
also fail with "transaction aborted". Pull this loop into a helper
so the idiom can be easily reused in several places throughout JGit.

Repository.getWorkTree is annotated as @NonNull, so the check
for it returning null is redundant.

Require callers to pass in valid sets for both want and have
collections. Offer PackWriter.NONE as a handy constant for an
empty collection for the have part of preparePack instead of null.

The RefTree graph needs to be quickly accessed to read references.
It is also distinct graph disconnected from the rest of the
repository. Store the commit and tree objects in their own pack.

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.

This experimental code can be enabled in $GIT_DIR/config:
[core]
repositoryformatversion = 1
[extensions]
refsBackendType = RefTree
When these are set the repository will read references from the
RefTree rooted by the $GIT_DIR/refs/txn/committed reference.
Update debug-rebuild-ref-tree to rebuild refs/txn/committed only from
the bootstrap layer. This avoids misuse by rebuilding using packed-refs
and $GIT_DIR/refs tree.

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.

With this support we no longer need the 'utf-8' alias. UTF-8 will be
automatically tried when the encoding header is not recognized and used
if the character sequence cleanly decodes as UTF-8.
Modernize some of the references to use StandardCharsets.
