Instead of overloading the pack's DfsStreamKey with negative positions
for the idx, reverse idx and bitmap, assign a unique DfsStreamKey for
each of these related streams.
Change-Id: Ie048036c74a1d1bbf5ea7e888452dc0c1adf992f
This renaming supports reusing DfsStreamKey in a future commit
to index other PackExt type streams inside of the DfsBlockCache.

Right now, PackParser relies on the object count from the pack header.
However, when creating Dfs INSERT packs, the object count is not known
at the beginning of the operation. And when we append the base to a
RECEIVE pack, we can't modify the pack header for object count in most
Dfs implementations.
Make it possible to tell PackParser the expected object count by adding
a setter for expectedObjectCount, implementation can overwrite the
object count in onPackHeader function.

Inline the old addRefToPrefixes, since it was just a glorified addAll.
Split getPrefixes into a variant, addPrefixesTo, that doesn't allocate a
small Collection on every invocation. Use this in the tight loop of
getTakenPrefixes.

If a block is missing from the block cache, open the pack stream,
retain the ReadableChannel, and turn on read-ahead. This should help
to load a medium sized pack into a cold cache more quickly from a
slower IO stream, as the pack is scanned sequentially and missing
blocks are more likely to be available through the read-ahead.

The merger is now able to react to the use of the merge attribute.
The value unset and the custom value 'binary' are handled (-merge
and merge=binary)
Since the specification of the merge attribute states that when the
attribute is unset, ours version must be kept in case of a conflict, we
don't overwrite the file but keep the local version.

These config options allow overriding the message type (error, warn or
ignore) of a specific message ID such as missingEmail.
The supported fsck message IDs are defined in ObjectChecker.ErrorType.
Since TransferConfig.FsckMode wasn't public parsing fsck configuration
options like e.g. fsck.missingEmail=ignore failed with an
IllegalAccessException. Fix this by declaring this enum public.

The cgit archive command creates a prefix (root) directory entry
in the archive file. That entry's time is set to the commit time.
This patch makes jgit's behavior consistent with with cgit:
prefix: hoge/ -> creates prefix directory "hoge/" entry.
prefix: hoge//// -> creates prefix directory "hoge/" entry.
prefix: hoge/foo -> does not create prefix directory entry, but for
each file/directory entry, prefix is added.

When running an automatic GC on a FileRepository, when the caller
passes a NullProgressMonitor, run the GC in a background thread. Use a
thread pool of size 1 to limit the number of background threads spawned
for background gc in the same application. In the next minor release we
can make the thread pool configurable.
In some cases, the auto GC limit is lower than the true number of
unreachable loose objects, so auto GC will run after every (e.g) fetch
operation. This leads to the appearance of poor fetch performance.
Since these GCs will never make progress (until either the objects
become referenced, or the two week timeout expires), blocking on them
simply reduces throughput.
In the event that an auto GC would make progress, it's still OK if it
runs in the background. The progress will still happen.
This matches the behavior of regular git.
Git (and now jgit) uses the lock file for gc.log to prevent simultaneous
runs of background gc. Further, it writes errors to gc.log, and won't
run background gc if that file is present and recent. If gc.log is too
old (according to the config gc.logexpiry), it will be ignored.

Allow fetch to accept a SHA-1 on the left hand side of a RefSpec,
enabling callers to pass a specific SHA-1 they want that may not have
been advertised by the remote repository. This can be passed along to
the network protocol to be sent in a "want" line.
Rest of the plumbing only cares about the ObjectId of the Ref in
the askFor map, so make up a fake name using ObjectId.name() to
pass the desired ObjectId into the network code.

When a command invoked from readPipe fails to launch (i.e. the exec call
fails due to a missing command executable), Process.start() throws,
which gets caught by the generic IOException handler, resulting in a
null return. This change detects this case and rethrows a
CommandFailedException instead.
Additionally, this change uses /bin/sh instead of bash for its posix
command failure test, to accomodate building in environments where bash
is unavailable.
