PackWriter: Fix the way delta chain cycles are prevented
Take a very simple approach to avoiding delta chains during object
reuse: objects are now always selected from the oldest pack that
contains them. This prevents cycles because a pack must not have
a cycle in the delta chain. If both objects A and B are chosen
out of the same source pack then there cannot be an A->B->A cycle.
The oldest pack is also the most likely to have the smallest deltas.
Its the biggest pack in the system and probably came from the clone
(or last GC) of this repository, where all objects were previously
considered and packed tightly together. If an object appears again
(for example due to a revert and a push into this repository) the
newer copy of won't be nearly as small as the older delta version
of it, even if the newer one is also itself a delta.
ObjectDirectory already enumerates objects during selection in this
newest->oldest order, so it already is supplying these assumptions
to PackWriter. Taking advantage of this can speed up selection by
a tiny amount by avoiding some tests, but can also help to prevent
a cycle needing to be broken on the fly during writing.
The previous cycle breaking logic wasn't fully correct either.
If a different delta base was chosen, the new delta base might not
have been written into the output pack before the current object,
forcing the use of REF_DELTA when OFS_DELTA is always smaller.
This logic has now been reworked to always re-check the delta base
and ensure it gets written before the current object.
If a cycle occurs, it gets broken the same way as before, by
disabling delta reuse and finding an alternative form of the
object, which may require inflating/deflating in whole format.

out that are duplicated with the cached pack. Typically these are
only cases where a blob or tree was cherry-picked forward, got a
copy or rename, or was reverted... all relatively infrequent events.
Speed up pruning of the thin pack object list by combining the phase
with the object representation selection. Implementers should already
be offering to reuse the object from the cached pack if it is stored
there, at which point the implementation can perform a very fast type
of containment test using the cached pack's identity rather than yet
another index lookup. For the local disk case this is probably not a
big improvement, but it does help on the DHT implementation where the
two passes combined into one reduces latency.

Create RemoteSession interface
The RemoteSession interface operates like a simplified version of
java.lang.Runtime with a single exec method (and a disconnect
method). It returns a java.lang.Process, which should begin execution

running commands. There is no longer a connect method, and most
implementations will contain the bulk of their code inside
Process.exec, or a constructor called by Process.exec. (See the
revised implementations of JschSession and ExtSession.)
Implementations can now configure their connections properly without
either ignoring the proper use of the interface or trying to adhere
to an overly strict interface with odd rules about what methods are
called first. For example, Jsch needs to create the output stream
before executing, which it now does in the process constructor. These

Use parent directory in InitCommand if directory is "."
If no directory is set before executing an InitCommand, the current
directory (".") is used by default. By calling File.getParentFile() we
get the actual directory this points to. Using this directory makes it
easier to read paths.

PushCommand: Allow adding any reference string
The simplified form of add(String) makes it easier for applications
to pass down user input and allow PushCommand to convert it to the
internal RefSpec object.

Make --git-dir optional for 'jgit init'
For compatibility reasons with regards to native git and also to
make the init command easier to use from the command line,
argument --git-dir should not be required.
Additionally the path created in case --git-dir is not supplied now is
canonical and thus easier to read.

Improve native Git transport when following repository
If the client is only following the remote repository and has not
created any new non-common commits, the client will wind up sending
a "have %s" line for each tag in the repository. For some projects
like git.git, this is 339 tags and growing, resulting in more than
16 KiB needing to be POSTed over 12 HTTP requests.
Teach UploadPack (server side) to always execute the okToGiveUp()
logic at least once per negotiation round to determine if the server
can compute a pack right now. If it can, shove in an "ACK %s ready"
message to tell the client this and try to prevent receiving ancient
tags in future negotiation rounds.
Teach BasePackFetchConnection (client side) to honor a "ACK %s ready"
from the remote and break out of its SEND_HAVE loop once the remote
knows it can create a pack. This avoids sending the remaining 307
tags of git.git.
These two changes together reduce the number of HTTP RPCs from 13
down to 3 in order to fetch from git.git over smart HTTP. If either
side is missing the change, the older behavior (and its 13 RPCs)
is used.
