Clarify the semantics of DfsRefDatabase#compareAndPut
DfsRefDatabase#compareAndPut had a vague semantics for reference
matching. Because of this, an operation to make a symbolic
reference had been broken for some DFS implementations even if they
followed the contract of compareAndPut. The clarified semantics
requires the implementations to satisfy the followings:
* Matching references should be both symbolic references or both
object ID references.
* If both are symbolic references, both should have the same target
name.
* If both are object ID references, both should have the same object
ID.
This semantics is defined based on
https://git.eclipse.org/r/#/c/77416/. Before this commit,
DfsRefDatabase couldn't see the target of symbolic references.
InMemoryRepository is changed to comply with the new semantics. This
semantics change can affect the existing DFS implementations that only
checks object IDs. This commit adds two tests that the previous
InMemoryRepository couldn't pass.

Repository: Introduce exactRef and findRef, deprecate getRef
The Repository class provides only one method to look up a ref by
name, getRef. If I request refs/heads/master and that ref does not
exist, getRef will look further in the search path:
ref/refs/heads/master
refs/heads/refs/heads/master
refs/remotes/refs/heads/master
This behavior is counterintuitive, needlessly inexpensive, and usually
not what the caller expects.
Allow callers to specify whether to use the search path by providing
two separate methods:
- exactRef, which looks up a ref when its exact name is known
- findRef, which looks for a ref along the search path
For backward compatibility, keep getRef as a deprecated synonym for
findRef.
This change introduces findRef and exactRef but does not update
callers outside tests to use them yet.

LocalDiskRepositoryTestCase and TestRepository have competing ideas
about time. Push them into MockSystemReader so they can
cooperate.
Rename getClock() methods that return Dates to getDate().

CherryPickCommand only works on a non-bare repository, as it must
modify the working tree and index in case of a merge conflict. In
tests, being able to recover from a merge conflict is less important,
as the caller should be able to control the full contents of files in
advance of the cherry-pick.

This includes both leaving existing Change-Ids alone (as, for example
Gerrit's commit-msg hook does) and programmatically setting a value.

TestRepository: Add a reset method to move HEAD around
This flushed out a number of bugs in the way DfsRefUpdate, or at least
the InMemoryRepository implementation, processes symrefs. These have
been fixed, to an extent, in InMemoryRepository, but other
implementations may still suffer from these bugs.

Eclipse has some problem re-running single JUnit tests if
the tests are in Junit 3 format, but the JUnit 4 launcher
is used. This was quite unnecessary and the move was not
completed. We still have no JUnit4 test.
This completes the extermination of JUnit3. Most of the
work was global searce/replace using regular expression,
followed by numerous invocarions of quick-fix and organize
imports and verification that we had the same number of
tests before and after.
- Annotations were introduced.
- All references to JUnit3 classes removed
- Half-good replacement for getting the test name. This was
needed to make the TestRngs work. The initialization of
TestRngs was also made lazily since we can not longer find
out the test name in runtime in the @Before methods.
- Renamed test classes to end with Test, with the exception
of TestTranslateBundle, which fails from Maven
- Moved JGitTestUtil to the junit support bundle

Introduce a http test bundle to make this functionality available for
EGit tests. A simple http server class is provided. The jetty version
was updated to a version that is also available via p2 (needed in EGit
UI tests).

This is a simple HTTP server that provides the minimum server side
support required for dumb (non-git aware) transport clients.
We produce the info/refs and objects/info/packs file on the fly
from the local repository state, but otherwise serve data as raw
files from the on-disk structure.
In the future we could better optimize the FileSender class and the
servlets that use it to take advantage of direct file to network
APIs in more advanced servlet containers like Jetty.
Our glue package borrows the idea of a micro embedded DSL from
Google Guice and uses it to configure a collection of Filters
and HttpServlets, all of which are matched against requests using
regular expressions. If a subgroup exists in the pattern, it is
extracted and used for the path info component of the request.
