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.

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.

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.

This tool scans all references in the repository and writes out a new
reference pointing to a single commit whose root tree is a RefTree
containing the current refs of this repository.
It alway skips storing the reference it will write to, avoiding the
obvious cycle.

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.

Currently execution of tests in pgm uses CLIGitCommand which
re-implements few things from Main. Unfortunately this can results in a
different test behavior compared to the real CLI runtime.
The change let CLIGitCommand extend Main and only slightly modifies the
runtime (stream redirection and undesired exit() termination).

git branch -d -h reports an error (because of missing -d option value)
but does not print the help as expected.
To fix this, CmdLineParser must catch, print but do not propagate
exceptions if help is requested.

In different places (Main, TextBuiltin, CLIGitCommand) we report fatal
errors and at same time want to check for fatal errors in the tests.
Using common API simplifies the error testing and helps to navigate to
the actual error check implementation.
