Root commits are commits with zero parents. If a commmit has no
parents it is the first commit in the repository. In general the root
commits should be unique for any given project, as the first commit
will be created at a different time, by a different user with its own
message. These root commits can be used as a "fingerprint" to
identify disjoint histories.

The FS class and the subclasses FS_POSIX assumed in the findHook()
method that every repository has a valid gitDir. But in tests when using
in-memory-repositories this is not true and this method was generating
NPEs. Change the method to return null if no repository directory can be
determined.

DfsGarbageCollector asks PackWriter for the set of objects packed
after the bitmap index is written out. This is now null as it was
cleared to release memory. Instead use PackBitmapIndexBuilder to
build the set as it also has the objects.
Reduce memory in PackBitmapIndexBuilder by fully discarding the
ObjectToPack instances. This was the original intent of commit
4bb523475d ("PackWriter: shed memory while creating bitmaps")
but failed as the instances were still held live here.
Switch to BlockList instead of ObjectToPack[]. This allows the
JVM to allocate many smaller arrays instead of one contiguous
array with 5.2M reference pointers. In a tight heap the smaller
allocations are more feasible.
Reduce the initial EWAHCompressedBitmaps for the 4 type maps. On
average a typical repository is 30% commits, 30% trees and 30% blobs.
These bitmaps are typically very dense. PackWriter orders objects by
commit, tree, blob when writing the file so these should always be a
very dense run of 1s with some 0s before and after. So even the 1/3rd
allocation is likely too large, but the later trim() will reduce the
internal buffer anyway.

Once bitmap creation begins the internal maps required for packing are
no longer necessary. On a repository with 5.2M objects this can save
more than 438 MiB of memory by allowing the ObjectToPack instances to
get garbage collected away.
Downside is the PackWriter cannot be used for any further opertions
except to write the bitmap index. This is an acceptable trade-off as
in practice nobody uses the PackWriter after the bitmaps are built.

For construction performance each new EWAHBitmap is allocated at the
roughly worst-case size the bitmap would need if all of the words must
be literal and no run length compression is available. In practice
this is far larger than is required, wasting heap memory while the
bitmaps are computed.
Trim down each bitmap to its minimum required size. This copies the
internal array to a new smaller array, allowing the GC to reclaim the
prior larger array for reuse.
A single bitmap of 5.2M bits is only 79 KiB of memory without this
trim call but 15,000 such bitmaps is 1.1 GiB. Trimming can help fit
a larger number of bitmaps during processing.

The bitmap preparer only needs commit graph topology; it does not use
the message body. Allow the RevWalk to free the body after the commit

The WorkingTreeIterator.isEntryIgnored() should use originally requested
file mode while descending to the file tree root and checking ignore
rules. Original code asking isEntryIgnored() on a file was using
directory mode instead if the .gitignore was not located in the same
directory.

While checking if we should consider an ignore rule without '[]'
brackets as a regular expression, check if the backslash escapes one of
the glob special characters '?', '*', '[', '\\'. If not, backslash is
not a part of a regex and should be treated literally.

Rather than lazily parsing the push in this method, parse it at the
end of recvCommands(), which already contains the necessary try/catch
for handling this error. This allows later callers to avoid having to
handle this condition superfluously.

Consider a BatchRefUpdate produced by Gerrit Code Review, where the
original command pushed over the wire might refer to
"refs/for/master", but that command is ignored and replaced with some
additional commands like creating "refs/changes/34/1234/1". We do not
want to store the cert in "refs/for/master@{cert}", since that may
lead someone looking to the ref to the incorrect conclusion that that
ref exists.
Add a separate put method that takes a collection of commands, and
only stores certs on those refs that have a matching command in the
cert.

Inspired by a proposal from gitolite[1], where we store a file in
a tree for each ref name, and the contents of the file is the latest
push cert to affect that ref.
The main modification from that proposal (other than lacking the
out-of-git batching) is to append "@{cert}" to filenames, which allows
storing certificates for both refs/foo and refs/foo/bar. Those
refnames cannot coexist at the same time in a repository, but we do
not want to discard the push certificate responsible for deleting the
ref, which we would have to do if refs/foo in the push cert tree
changed from a tree to a blob.
The "@{cert}" syntax is at least somewhat consistent with
gitrevisions(7) wherein @{...} describe operators on ref names.
As we cannot (currently) atomically update the push cert ref with the
refs that were updated, this operation is inherently racy. Kick the can
down the road by pushing this burden on callers.

The test helper method `indexState` in `RepositoryTestCase` is
very useful for writing tests, even in cases where we need to
do things like create more than one repository for a test and
thus we don't want to use the built-in `db` member variable that
exists in `RepositoryTestCase`. Since the method is static,
we can move it up to the parent class `LocalDiskRepositoryTestCase`,
where it can be used by tests that aren't a great fit for inheriting
directly from `RepositoryTestCase`.
