It's useful to have ReflogEntry refactored out so it can be
used by clients via the JGit API.

* stable-0.12:
Implement the no-done capability

Smart HTTP clients may request both multi_ack_detailed and no-done in
the same request to prevent the client from needing to send a "done"
line to the server in response to a server's "ACK %s ready".
For smart HTTP, this can save 1 full HTTP RPC in the fetch exchange,
improving overall latency when incrementally updating a client that
has not diverged very far from the remote repository.
Unfortuantely this capability cannot be enabled for the traditional
bi-directional connections. multi_ack_detailed has the client sending
more "have" lines at the same time that the server is creating the
"ACK %s ready" and writing out the PACK stream, resulting in some race
conditions and/or deadlock, depending on how the pipe buffers are
implemented. For very small updates, a server might actually be able
to send "ACK %s ready", then the PACK, and disconnect before the
client even finishes sending its first batch of "have" lines. This
may cause the client to fail with a broken pipe exception. To avoid
all of these potential problems, "no-done" is restricted only to the
smart HTTP variant of the protocol.

When the client is clearly making a smart HTTP request to our smart
HTTP server, return any errors like RepositoryNotFoundException or
ServiceNotEnabledException inside of the payload as a Git level ERR
message, rather than an HTTP error code.
This prevents the C Git command line client from retrying a failed
"$URL/info/refs?service=git-upload-pack" request without the smart
service URL, only to fail again with "403 Forbidden" when the dumb
as-is service has been disabled by the server configuration, or is
unavailable because the repository is not on the local filesystem.

Some clients coming through proxies may advertise a different
Accept-Encoding, for example "Accept-Encoding: gzip(proxy)".
Matching by substring causes us to identify this as a false positive;
that the client understands gzip encoding and will inflate the
response before reading it.
In this particular case however it doesn't. Its the reverse proxy
server in front of JGit letting us know the proxy<->JGit link can
be gzip compressed, while the client<->proxy part of the link is not:
client <-- no gzip --> proxy <-- gzip --> JGit
Use a more standard method of parsing by splitting the value into
tokens, and only using gzip if one of the tokens is exactly the
string "gzip". Add a unit test to make sure this isn't broken in
the future.

Using a resolver and factory pattern for the anonymous git:// Daemon
class makes transport.Daemon more useful on non-file storage systems,
or in embedded applications where the caller wants more precise
control over the work tasks constructed within the daemon.
Rather than defining new interfaces, move the existing HTTP ones
into transport.resolver and make them generic on the connection
handle type. For HTTP, continue to use HttpServletRequest, and
for transport.Daemon use DaemonClient.
To remain compatible with transport.Daemon, FileResolver needs to
learn how to use multiple base directories, and how to export any
Repository instance at a fixed name.

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

When the Config is changed, it should be saved back to its local
file. This ensure that a future call to getConfig() won't wipe
out the edits that were just made.

Each time getConfig() is called on FileRepository, it checks the
last modified time of both ~/.gitconfig and $GIT_DIR?config. If
$GIT_DIR/config appears to have been modified, it is read back in
from disk and the current config is wiped out.
When mutating a configuration file, this may cause in-memory edits
to disappear. To avoid that callers need to avoid calling getConfig
until after the configuration has been saved to disk.
Unfortunately the API is still horribly broken. Configuration should
be modified only while a lock is held on the configuration file, very
similar to the way a ref is updated via its locking protocol. But our
existing API is really broken for that so we'll have to defer cleaning
up the edit path for a future change.

This change is based on http://egit.eclipse.org/r/#change,1652
by David Green. The change adds the concept of a CredentialsProvider
which can be registered for git transports and which is
responsible to return credential-related data like passwords and
usernames. Whenenver the transports detects that an authentication
with certain credentials has to be done it will ask the
CredentialsProvider for this data. Foreseen implementations for
such a Provider may be a EGitCredentialsProvider (caching
credential data entered e.g. in the Clone-Wizzard) or a NetRcProvider
(gathering data out of ~/.netrc file).

The auth-scheme token (like "Basic" or "Digest") is not specified in a
case sensitive way. RFC2617 (http://tools.ietf.org/html/rfc2617) specifies
in section 1.2 the use of a "case-insensitive token to identify the
authentication scheme". Jetty, for example, uses "basic" as token.

This move isolates all of the local file specific implementation code
into a single package, where their package-private methods and support
classes are properly hidden away from the rest of the core library.
Because of the sheer number of files impacted, I have limited this
change to only the renames and the updated imports.

When the surrounding code is already heavily based upon the
assumption that we have a FileRepository (e.g. because it
created that type of repository) keep the type around and
use it directly. This permits us to continue to do things
like save the configuration file.

This lets us remove the subclass RepositoryConfig and stop having
a specialized configuration type for repository, letting us instead
focus the config type heirarchy on type-of-storage rather than use.

This patch makes RecordingLogger consistent with the Logger interface and allows to

The HTTP server side code now uses the same approach that the smart
HTTP client code uses when preparing a request body. The payload
is streamed into a TemporaryBuffer of limited size. If the entire
data fits, its compressed with gzip if the user agent supports that,
and a Content-Length header is used to transmit the fixed length
body to the peer. If however the data overflows the limited memory
segment, its streamed uncompressed to the peer.
One might initially think that larger contents which overflow
the buffer should also be compressed, rather than sent raw, since
they were deemed "large". But usually these larger contents are
actually a pack file which has been already heavily compressed by
Git specific routines. Trying to deflate that with gzip is probably
going to take up more space, not less, so the compression overhead
isn't worthwhile.
This buffer and compress optimization helps repositories with a
large number of references, as their text based advertisements
compress well. For example jgit's own native repository currently
requires 32,628 bytes for its full advertisement of 489 references.
Most repositories have fewer references, and thus could compress
their entire response in one buffer.

If the application wants to, it can use sendError(String) to send one
or more error messages to clients before the advertisements are sent.
These will cause a C Git client to break out of the advertisement
parsing loop, display "remote error: message\n", and terminate.
Servers can optionally use this to send a detailed error to a client
explaining why it cannot use the ReceivePack service on a repository.
Over smart HTTP these errors are sent in a 200 OK response, and
are in the payload, allowing the Git client to give the end-user
the custom message rather than the generic error "403 Forbidden".

Any messages received on side band #2 that aren't scraped as a
progress message into our ProgressMonitor are now forwarded to a
buffer which is later included into the OperationResult object.
Application callers can use this buffer to present the additional
messages from the remote peer after the push or fetch operation
has concluded.
The smart push connections using the native send-pack/receive-pack
protocol now request side-band-64k capability if it is available
and forward any messages received through that channel onto this
message buffer. This makes hook messages available over smart HTTP,
or even over SSH.
The SSH transport was modified to redirect the remote command's
stderr stream into the message buffer, interleaved with any data
received over side band #2. Due to buffering between these two
different channels in the SSH channel mux itself the order of any
writes between the two cannot be ensured, but it tries to stay close.
The local fork transport was also modified to redirect the local
receive-pack's stderr into the message buffer, rather than going to
the invoking JVM's System.err. This gives applications a chance
to log the local error messages, rather than needing to redirect
their JVM's stderr before startup.
To keep things simple, the application has to wait for the entire
operation to complete before it can see the messages. This may
be a downside if the user is trying to debug a remote hook that is
blocking indefinitely, the user would need to abort the connection
before they can inspect the message buffer in any sort of UI built
on top of JGit.

Ensure the background Jetty threads have been able to write the
request log record before the JUnit thread tries to read the set
of requests back. This wait is necessary because the JUnit thread
may be able to continue as soon as Jetty has finished writing
the response onto the socket, and hasn't necessarily finished the
post-response logging activity.
By using a semaphore with a fixed number of resources, and using
one resource per request, but all of them when we want to read the
log, we implement a simple lock that requires there be no active
requests when we want to get the log from the JUnit thread.
