This fix makes sure the readPipe methods drains the stderr
pipe and close the subprocess' stdin stream before reading
the process outputs.
I never managed to repeat the reported problem myself, so this
may help in diagnosing the probelm on other peoples machines.

Smart HTTP clients may request both multi_ack_detailed and no-done in
the same request to prevent the client from needing to send a "done"
line to the server in response to a server's "ACK %s ready".
For smart HTTP, this can save 1 full HTTP RPC in the fetch exchange,
improving overall latency when incrementally updating a client that
has not diverged very far from the remote repository.
Unfortuantely this capability cannot be enabled for the traditional
bi-directional connections. multi_ack_detailed has the client sending
more "have" lines at the same time that the server is creating the
"ACK %s ready" and writing out the PACK stream, resulting in some race
conditions and/or deadlock, depending on how the pipe buffers are
implemented. For very small updates, a server might actually be able
to send "ACK %s ready", then the PACK, and disconnect before the
client even finishes sending its first batch of "have" lines. This
may cause the client to fail with a broken pipe exception. To avoid
all of these potential problems, "no-done" is restricted only to the
smart HTTP variant of the protocol.

* stable-0.12:
Fix sorting of names in RefDirectory
Make running static checks configurable in maven build
Add constants for gerrit change id configuration
RefDirectory did not correctly follow the contract of RefList. The
contract says if you use add() method of RefList builder, you MUST
sort() it afterwards, and later every other method assumes that list
is properly sorted (especially the binary search in the find() and
get() methods). Instead RefDirectory class tried to scan the refs
recursively while sorting every folder in the process before
processing and did not call sort().
For example, when scanning the contents of refs/tags project1 string
is smaller than project1-*, so it will recursively go into the folder
and add these tags first and only then will add project-* ones. This
will result in a broken list (any project1-* string is less than
project1/* one, but they all appear after them in the list), that's
why binary search will fail making loose RefList and the whole local
RefMap completely unusable.

Add handling of CHERRY_PICK_HEAD file in .git (similar to MERGE_HEAD),
which is written in case of a conflicting cherry-pick merge.
It is used so that Repository.getRepositoryState can return the new
states CHERRY_PICKING and CHERRY_PICKING_RESOLVED. These states, as well
as CHERRY_PICK_HEAD can be used in EGit to properly show the merge tool.
Also, in case of a conflict, MERGE_MSG is written with the original
commit message and a "Conflicts" section appended. This way, the
cherry-picked message is not lost and can later be re-used in the commit
dialog.

Change I61a1b45db2d60fdcc0f87373ac6fd75ac4c4a202 fixed a possible NPE
occurring for newly created repositories - but in that case a wrong
value (false = not modified) was returned.
If a current version of the index file exists (liveFile), but there is
no snapshot, this means that there have been modifications (i.e. true
has to be returned).

When a new Git instance for an exisiting git repository should be
created there are two use-cases: either the application has already a
Repository instance in hand or the application knows where the
repository resides in the filesystem. Two methods are added to
explicitly support these use-cases: wrap(Repository db) and open(File
gitDir)

The 'Counting objects' phase of PackWriter requires good hit rates
from the DeltaBaseCache while walking trees, the deltas need to find
their bases in the cache in order to inflate in a reasonable time.
If JGit is running in a multi-threaded server, such as Gerrit Code
Review, each thread needs its own DeltaBaseCache to prevent one thread
from evicting the other thread's relevant bases. Move the cache to be
per-ObjectReader, lazily allocated when required by a PackFile.

If a repository has an alternate object database, the alternate has
its references advertised as ".have" lines, which permits the client
to use these as delta base candidates when generating the pack. If
setCheckReferencedObjectsAreReachable(true) is used, these additional
have lines need to be considered in addition to the advertised refs.

We sometimes face the problem that the file .git/index.lock
can't deleted causing JGit operations to fail. Problem is
that LockFile.unlock() simply deletes the lockfile and ignores the
return value of File.delete(). Instead use
FileUtils.delete() with retry option. This method will retry the
deletion of the file at most 10 times with sleeps inbetween.

When the client is clearly making a smart HTTP request to our smart
HTTP server, return any errors like RepositoryNotFoundException or
ServiceNotEnabledException inside of the payload as a Git level ERR
message, rather than an HTTP error code.
This prevents the C Git command line client from retrying a failed
"$URL/info/refs?service=git-upload-pack" request without the smart
service URL, only to fail again with "403 Forbidden" when the dumb
as-is service has been disabled by the server configuration, or is
unavailable because the repository is not on the local filesystem.

Permit applications embedding GitServlet to wrap the

To help applications inspect state of the operation,
expose the UploadPack or ReceivePack object into a
request attribute. This can be useful for logging,
or to implement throttling of requests like Gerrit
Code Review uses to prevent server overload.
