Attempt to fix graph layout when new heads are introduced
Sometime the new commit is no allocated onto a new lane leading to
the commit being drawn on the wrong branch and something that looks
like a merge.
The drawback is that this also changes existing valid graphs.

Use full branch name when getting ref in BranchTrackingStatus
In case there is both a tag and branch called "foo", the tag is returned
if calling getRef with the short name. By using refs/heads/foo, the
branch is returned.

Ignore bitmap indexes that do not match the pack checksum
If `git gc` creates a new pack with the same file name, the
pack checksum may not match that in the .bitmap. Fix the PackFile
implementaion to silently ignore invalid bitmap indexes.

ResetCommand: Allow reset on unborn branch when ref not specified
In C Git 1.8.2, "git reset" now also works on an unborn branch (no HEAD
yet) if no explicit ref was specified. In that case, it is treated as a
reset to an empty tree.
This can be useful for callers because "unborn branch" no longer has to
be special-cased to "git rm --cached".

OpenJDK 7 does not benefit from using an inflate stride on the input
array. The implementation of java.util.zip.Inflater supplies the
entire input byte[] to libz, with no regards for the bounds supplied.
Slicing at 512 byte increments in DfsBlock no longer has any benefit.
In OpenJDK 6 the native portion of Inflater used GetByteArrayRegion
to obtain a copy of the input buffer for libz. In this use case
supplying a small stride made sense, it avoided allocating space
for and copying data past the end of the object's compressed stream.
In OpenJDK 7 the native code uses GetPrimitiveArrayCritical,
which tries to avoid copying by freezing Java garbage collection
and accessing the byte[] contents in place. On OpenJDK 7 derived
JVMs it is likely more efficient to supply the entire DfsBlock.
Since OpenJDK 5 and 6 are deprecated and replaced by OpenJDK 7
it is reasonable to suggest any consumers running JGit with DFS
support use an OpenJDK 7 derived JVM. However, JGit still targets
local filesystem support on Java 5, so it is still not reasonble to
apply this same simplification to the internal.storage.file package.

Fix HTTP response processing for WWW-Authenticate headers
The original code was able to process only one WWW-Authenticate
header in an HTTP response, and if this header was not one of
two expected, authentication failed regardless of that there
could be other headers in the response.
All WWW-Authenticate headers in an HTTP response have to be
browsed to find one of supported, i.e. Basic or Digest.
By that if both are present, the Digest one should be used
as more preferable.

Advertise capabilities with no refs in upload service.
With reference hiding, it is possible for a repository to appear
empty when all refs are hidden. This causes capabilities to not be
advertised either, since they are published with the first reference,
breaking fetch by SHA1 support.
Always advertise the capabilites by publishing the symbolic capabilities
reference when the repository has no references to advertise (similar to
the receive service).

Associate each RequestPolicy with an implementation of a
RequestValidator interface that contains the validation logic. The
checkWants method is only called if there are wants that were not
advertised, since clients may always request any advertised want
according to the git protocol. Calling the method only once at the
end of parsing the want list also means policy implementations can be
stateful, unlike the previous switch statement inside a loop.
For the special handling of unidirectional pipes, simply check
isBiDirectional() and delegate to other implementations if necessary.

UploadPack: configure RequestPolicy with TransportConfig
C git 1.8.2 supports setting the equivalent of RequestPolicy.TIP with
uploadpack.allowtipsha1. Parse this into TransportConfig and use it
from UploadPack. An explicitly set RequestPolicy overrides the config,
and the policy may still be upgraded on a unidirectional connection to
avoid races.
Defer figuring out the effective RequestPolicy to later in the
process. This is a minor semantic change to fix a bug: previously,
calling setRequestPolicy(ADVERTISED) _after_ calling
setBiDirectionalPipe(true) would have reintroduced the race condition
otherwise fixed by 01888db892.

that limits which refs are advertised, but clients may learn of a
SHA-1 that the server should have as a ref tip through some
alternative means. Support serving such objects from the server side
with a new RequestPolicy.
As with ADVERTISED, we need a special relaxed RequestPolicy to allow
commits reachable from the set of valid tips for unidirectional
connections.

Using a simple bucket sort algorithm, that time is reduced to 450ms.
