Since the introduction of generic type parameter inference in Java 7,
it's not necessary to explicitly specify the type of generic parameters.
Enable the warning in Eclipse, and fix all occurrences.

Set missingOverrideAnnotation=warning in Eclipse compiler preferences
which enables the warning:
The method <method> of type <type> should be tagged with @Override
since it actually overrides a superclass method
Justification for this warning is described in:
http://stackoverflow.com/a/94411/381622
Enabling this causes in excess of 1000 warnings across the entire
code-base. They are very easy to fix automatically with Eclipse's
"Quick Fix" tool.
Fix all of them except 2 which cause compilation failure when the
project is built with mvn; add TODO comments on those for further
investigation.

Otherwise these methods may produce unexpected results if used for
strings that are intended to be interpreted locale independently.
Examples are programming language identifiers, protocol keys, and HTML
tags. For instance, "TITLE".toLowerCase() in a Turkish locale returns
"t\u0131tle", where '\u0131' is the LATIN SMALL LETTER DOTLESS I
character.

Add a new exception type that server implementations can throw when a
client attempts to make an unauthorized LFS operation, which will result
in HTTP 401 Unauthorized being returned to the client.
An example of this is a Gerrit server that rejects a request to perform
an LFS operation on a ref that is not visible to the caller.
As defined in the LFS spec [1] the request may include authentication,
and per RFC 2616 [2], "401 response indicates that authorization has been
refused for those credentials".

Additionally, update LfsPointer to support the legacy version URL [1] as
described in [2], and to allow arbitrary fields in the pointer file.

Adds a JGit built-in implementation of the "git lfs smudge" filter. This
filter should do the same as the one described in [1] besides that it
only supports the local case when the lfs objects are already present in
the media directory. Remote cases where download of LFS objects from an
LFS server is needed will be done in a later commit.

Adds a JGit built-in implementation of the "git lfs clean" filter. This

filter is written in Java and can be called by JGit without forking new
processes it should be much faster

Since [1], the git-lfs specification allows the server to return
HTTP 507 if there is insufficient storage for the uploaded object(s).
Add a new exception class, which implementations may throw from the
getRepository() method, causing HTTP 507 to be returned to the client.

The git-lfs specification [1] describes the following optional status codes
that may be returned:
429 - The user has hit a rate limit with the server. Though the API does
not specify any rate limits, implementors are encouraged to set some
for availability reasons.
509 - Returned if the bandwidth limit for the user or repository has been
exceeded. The API does not specify any bandwidth limit, but implementors
may track usage.
Add two new exception classes to represent these cases. Implementations may
throw these from #getLargeFileRepository(), causing the corresponding HTTP
status codes to be returned to the client.

According to the specification [1] the server may return the following
HTTP error responses:
- 403: The user has read, but not write access.
- 404: The repository does not exist for the user.
- 422: Validation error with one or more of the objects in the request.
In the current implementation, however, getLargeFileRepository can only
return null to indicate an error. This results in the error code:
- 503: Service Unavailable
being returned to the client regardless of what the actual reason was.
Add exception classes to cover these cases, derived from a common base
exception, and change the specification of getLargeFileRepository to throw
the base exception.
In LfsProtocolServlet#post, handle the new exceptions and send back the
appropriate HTTP responses as mentioned above.
The specification also mentions several other optional response codes (406,
429, 501, and 509) but these are not implemented in this commit. It should
be trivial to implement them in follow-up commits.
