Before this change any files in the conflicting set would
also be listed in the the other IndexDiff Sets which is
confusing. With this change a conflicting file will not
be included in any of the other sets.

Submodules are supposed to be handled by separate operations, so
we should ignore them on checkout, just like C Git does.
This fix does not add submodule support. We just try harder
to ignore them.

jgit.storage.dht is a storage provider implementation for JGit that
permits storing the Git repository in a distributed hashtable, NoSQL
system, or other database. The actual underlying storage system is
undefined, and can be plugged in by implementing 7 small interfaces:
* Database
* RepositoryIndexTable
* RepositoryTable
* RefTable
* ChunkTable
* ObjectIndexTable
* WriteBuffer
The storage provider interface tries to assume very little about the
underlying storage system, and requires only three key features:
* key -> value lookup (a hashtable is suitable)
* atomic updates on single rows
* asynchronous operations (Java's ExecutorService is easy to use)
Most NoSQL database products offer all 3 of these features in their
clients, and so does any decent network based cache system like the
open source memcache product. Relying only on key equality for data
retrevial makes it simple for the storage engine to distribute across
multiple machines. Traditional SQL systems could also be used with a
JDBC based spi implementation.
Before submitting this change I have implemented six storage systems
for the spi layer:
* Apache HBase[1]
* Apache Cassandra[2]
* Google Bigtable[3]
* an in-memory implementation for unit testing
* a JDBC implementation for SQL
* a generic cache provider that can ride on top of memcache
All six systems came in with an spi layer around 1000 lines of code to
implement the above 7 interfaces. This is a huge reduction in size
compared to prior attempts to implement a new JGit storage layer. As
this package shows, a complete JGit storage implementation is more
than 17,000 lines of fairly complex code.
A simple cache is provided in storage.dht.spi.cache. Implementers can
use CacheDatabase to wrap any other type of Database and perform fast
reads against a network based cache service, such as the open source
memcached[4]. An implementation of CacheService must be provided to
glue this spi onto the network cache.

The filter did not correctly match smart HTTP client requests,
so it always fell back on HTTP status codes for errors. This
usually causes a smart client to retry a dumb request, which
is not what the server wants.

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).
