UploadPack: refactor want validation
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

alternative means. Support serving such objects from the server side

Fix AnyObjectId's generic type declaration of Comparable
If you look at any implementation of Comparable in the JDK, you'll see
that the type parameter for Comparable is supposed to be the type of
the implementing class:
The current type signature of Comparable<Object> is pretty awful, at the
very least because you can not, in fact, successfully compare
AnyObjectId with any random subclass of Object. It also causes problems
with type-inference and the scala.math.Ordering trait in Scala.
In order to compile, this change *does* require removing the
AnyObjectId.ompareTo(Object) method - which actually only ever cast
to AnyObjectId in any case. Nothing in the JGit test suite requires this
method, but it might constitute a breaking API change, so it would be
best if it can be added in time for JGit 3.0.
There was a severe bug in CommitCommand which could corrupt
repos. When merging an annotated tag the JGit MergeCommand writes
correctly the ID of the tag (and not the id of the commit the tag was
pointing to) into MERGE_HEAD. Native git does the same. But
CommitCommand was reading this file and trusting blindly that it will
contain only IDs of commits. Then the CommitCommand created a
commit which has as parent a non-commit object (the tag object). That's
so corrupt that even native git gives up when you call "git log" in
such a repo.
To reproduce that with EGit simply right-click on a tag in the
Repository View and select Merge. The result was a corrupt repo!
