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.

By showing the bootstrap layer in getAdditionalRefs() garbage
collector code can be more RefDatabase agnostic and not care about
the special case of RefTree and RefTreeNames for the purposes of
building up the roots to GC. Instead they can combine getRefs(ALL)
and getAdditionalRefs() and have a clean set of roots.

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.

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.

type to check a set of objects from a number of storage options.

If a file (e.g. "A") and a subtree file (e.g. "A/foo.c") both appear
in the DirCache this cache should not be written out as a tree object.
The "A" file and "A" subtree conflict with each other in the same tree
and will fail fsck.
Detect this condition during DirCacheBuilder and DirCacheEditor
finish() so the application can be halted early before it updates a
DirCache that might later write an invalid tree structure.

allow DirCacheBuilderIterator to copy conflicting entries into
the output cache.

PathFilter and PathFilterGroup form JGit's implementation of git's
path-limiting feature in commands like log and diff. To save time
when traversing trees, a path specification
foo/bar/baz
tells the tree walker not to traverse unrelated trees like qux/. It
does that by returning false from include when the tree walker is
visiting qux and true when it is visiting foo.
Unfortunately that test was implemented to be slightly over-eager: it
doesn't only return true when asked whether to visit a subtree "foo"
but when asked about a plain file "foo" as well. As a result, diffs
and logs restricted to some-file/non-existing-suffix unexpectedly
match against some-file:

Clean up LICENSE file

Fix it by checking against the entry's mode.
Gitiles +log has the same bug and benefits from the same fix.
Callers know not to worry about what subtrees are included in the tree
walk because shouldBeRecursive() returns true in this case, so this
behavior change should be safe. This also better matches the behavior
of C git:
$ empty=$(git mktree </dev/null)
$ git diff-tree --abbrev $empty HEAD -- LICENSE/no-such-file
$ git diff-tree --abbrev $empty HEAD -- tools/no-such-file
