Support per-BatchRefUpdate atomic transactions
Repurpose RefDatabase#performsAtomicTransactions() slightly, to
indicate that the backend _supports_ atomic transactions, rather than
the current definition, which is that the backend always _uses_ atomic
transactions regardless of whether or not the caller actually wants
them. Allow BatchRefUpdate callers to turn off atomic transactions by
calling setAtomic(false). Defaulting to true means this is backwards
compatible.

Make UploadPack observe exceptions reading refs
Now if refs are unreadable when serving an upload pack the handler
will fail due to the actual underlying failure. Previously all wants
would be rejected as invalid because Repository.getAllRefs() returned
an empty map.
Testing this required a new subclass of InMemoryRepository so that
an IOException could be injected at the correct time.

Fix CommitCommand to be able to skip writing to RefLog
CommitCommand already provided a method to set the comment which should
be written into the reflog. The underlying RefUpdate class supported to

Filter corrupt objects from DfsReader.selectObjectRepresentation()
PackWriter.writeObject() can get into an infinite loop when corrupt
packs are present. When it finds a pack file with an object that can be
reused it calls DfsPackFile.copyAsIs(). If that method sees an invalid
CRC, it adds the object to the DfsPackFile's corrupt object list and
throws a CorruptObjectException, which it later catches as an
IOException and wraps in a
StoredObjectRepresentationNotAvailableException.
PackWriter.writeObjectImpl() catches that SORNAE and retries the
operation by calling DfsReader.selectObjectRepresentation(). But
currently that method returns the same object which was just seen to
be corrupt.
Change DfsPackFile.isCorrupt() from private to package private, and use
that method in DfsReader.selectObjectRepresentation() to filter out
corrupt objects.
The stack traces that show the problem are:
org.eclipse.jgit.errors.CorruptObjectException.<init>(CorruptObjectException.java:113)

Remove repository from cache when it's closed
RepositoryCache has 2 methods to remove a repository from the cache but
they are never called when a repository is closed. Users of the cache
were expected to call one of those 2 methods but how could they have
called them at proper time without having visibility of the repository
usage count.
Ideally, I would have reworked the RepositoryCache to wrap any
repository it opens in a class that would be responsible to unregister
them from the cache when it's really closed, i.e. when usage counter
reaches 0. The problem preventing the wrapping solution is the
RepositoryCache.register method that allows to register an already
opened repository in the cache. Such repositories cannot be wrapped
because callers are still holding a reference on the unwrapped
repository.
Document that RepositoryCache.close method is removing the repository
from the cache as well as closing it and rework
RepositoryCache.unregister method to only remove the repository from the
cache. Use the latter to unregister repository when Repository.doClose
is getting executed.

Fix RefDirectory not closing resources
When repositories are opened using the RepositoryCache, they are kept in
memory and when the repository usage counter reaches 0, the
Repository.close method is called which then calls close method on its
reference and object databases.
The problem is that RefDirectory.close method was a no-op and the
reference database was kept in memory. This problem is only happening
when opening a repository using the RepositoryCache because it never
evicts repositories, it's just calling the close method.

Fix repository cache never closing repository
Repository has a usage counter that is initialized to 1 at
instantiation and this counter is decremented when Repository.close
method is called. There is also a Repository.incrementOpen method that
RepositoryCache uses to increment the usage count when it's returning a
repository that is already opened.
The problem was that RepositoryCache was incrementing the usage count
for repositories that it just opened or registered. The usage count was
2 when it should have been 1.
Incrementing usage count is now only be done for repository that are
served from the cache.
This bug is causing slow memory increase of our Gerrit server until the
server become slow. Even if the RepositoryCache is using SoftReference,
it seems that the JVM is not garbage collecting the repositories because
it's not yet on the edge of being out of memory.
To test this change, I replicated all repositories(11k) from Gerrit
master to one slave. The Gerrit master used memory after this test was
10GB without this change and 3.5GB with.

Add config parameter gc.prunePackExpire for packfile expiration
JGit's Garbage Collector is repacking relevant objects into new
packfiles and is afterwards deleting the now obsolete packfiles. But to
prevent problems caused by race conditions JGit was not deleting
packfiles when they are too young. The same mechanism as for loose
objects and the config parameter gc.pruneExpire was used.
But JGit was reusing the parameter gc.pruneExpire also for packfiles
which may cause a lot of filesystem consumption if gc.pruneExpire was
set to the default of 2 weeks. Only two weeks after packfile creation gc
was allowed to delete this packfile.
This change introduces a new config paramter gc.prunePackExpire with a
default of "1.hour". This parameter is used when packfiles are deleted.
Only packfiles older than the specified time can be deleted.
For loose objects the behaviour is not changed and only the old
parameter gc.pruneExpire is relevant.

Fix RebuildRefTree trying to add HEAD twice to RefTree
14dfa70520 fixed the problem that HEAD wasn't added to the reftree when
rebuilding the reftree in an empty repository where HEAD isn't yet
resolvable. Since non-resolvable refs are filtered out by
RefDatabase.getRefs(ALL) we have to add HEAD to the reftree explicitly
in this special case.
This fix resulted in another bug: rebuilding the reftree in a repository
which has a resolvable HEAD failed with a DirCacheNameConflictException
in RefTree.apply(). If HEAD is resolvable RefDatabase.getRefs(ALL) does
not filter out HEAD. This results in two identical CREATE commands for
HEAD which RefTree.apply() refuses to execute.
Fix this by no longer creating a duplicate CREATE command for HEAD.

In follow up changes we should:
- implement getVerifyAction() and do actual verification. Subclasses of
S3Repository can implement caching for object meta data (size) in order
to avoid extra roundtrips to S3. Verification should ensure that meta
data store and content of S3 storage are in sync
- HEAD request used in S3Repository.getSize() seems to always return
Content-length 0 in contrast to the documentation [2]. So getSize() does
detect if the object exists in S3 or not but in case the object exists
it always returns size 0
