This might be somewhat surprising behavior to users who might
naturally assume the following invariant:
ident.equals(parseIdent(ident.toExternalString()))
This invariant does not hold since whitespace is only trimmed during
serialization. We don't want to mess with the strings during
initialization, as this is called during the highly-optimized commit
parsing codepath.

We've found in Gerrit Code Review that it is common to pass around
both an ObjectReader (or more commonly a RevWalk wrapping one) and an
ObjectInserter. These code paths often assume that the ObjectReader
can read back any objects created by the ObjectInserter without
flushing. However, we previously had no way to enforce that constraint
programmatically, leading to hard-to-spot problems.
Provide a solution by exposing the ObjectInserter that created an
ObjectReader, when known. Callers can either continue passing both
objects and check:
reader.getCreatedFromInserter() == inserter
or they can just pass around ObjectReader and extract the inserter
when it's needed (checking that it's not null at usage time).

CommitCommand already provided a method to set the comment which should
be written into the reflog. The underlying RefUpdate class supported to
skip writing a reflog entry. But through the CommitCommand API it was
not possible to prevent writing a reflog entry. Fix this and allow
creating commits which don't occur in the reflog.

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.

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.

When checking out commits/branches JGit was triggering correctly

CheckoutCommand to properly call filters.

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.

This commit introduces a FileModeStrategy to
the FileTreeIterator class. This provides a way to
allow different modes of traversing a file tree;
for example, to control whether or not a nested
.git directory should be treated as a gitlink.

TreeWalk provides the new method getEolStreamType. This new method can
be used with EolStreamTypeUtil in order to create a wrapped InputStream
or OutputStream when reading / writing files. The implementation
implements support for the git configuration options core.crlf, core.eol
and the .gitattributes "text", "eol" and "binary"

There's only one test method in this module and it's quite long, so
rather than using a try-with-resource and having to indent a huge
block of existing code, make the Git a member variable that gets
initialised and closed in @Before and @After annotated methods.
The methods are named 'before' and 'after' rather than the conventional
'setUp' and 'tearDown' so as not to conflict with the names of the
existing methods in LocalDiskRepositoryTestCase.
