This increases type-safety and is ground work for support of the
"tree:<depth>" filter.

This code is not specific to V2 of the protocol, so it doesn't belong
there. Move it to its own class.

Capture the internal "want X not valid" state as a specific subclass
of PackProtocolException, allowing this to be more easily identified
in server stack traces and wrapper application code.

ObjectId.fromString already throws InvalidObjectIdException for most
malformed object ids, but for this kind it previously threw
IllegalArgumentException.  Since InvalidObjectIdException is a child of
IllegalArgumentException, callers that catch IllegalArgumentException
will continue to work.

The invalidId message in JGitText and the asAscii bad id both contain a
colon, so the resulting message would say

	Invalid id: : a78987c98798ufa

Fix it by keeping the colon in the translated message and not adding
another colon programmatically.

Noticed by code inspection.

A few classes such as Constanrs are marked with @SuppressWarnings, as are
toString() methods with many liternal, but otherwise $NLS-n$ is used for
string containing text that should not be translated. A few literals may
fall into the gray zone, but mostly I've tried to only tag the obvious
ones.

The strings are externalized into the root resource bundles.
The resource bundles are stored under the new "resources" source
folder to get proper maven build.

Strings from tests are, in general, not externalized. Only in
cases where it was necessary to make the test pass the strings
were externalized. This was typically necessary in cases where
e.getMessage() was used in assert and the exception message was
slightly changed due to reuse of the externalized strings.
