Abstract SSH setup to support GIT_SSH
In order to honor GIT_SSH the TransportGitSsh class needs to run the
process named by the GIT_SSH environment variable and use that as the
pipes for connectivity to the remote peer. Refactor the current
transport code to support a different type of pipe connectivity, so we
can later add GIT_SSH.

that file is private to the thread that is writing it, and no others

of a larger 64 bit integer. If the file size was larger than 4 GB
the counter could overflow and impact the key, changing the hash,

Guard against this overflow condition by capping the count for each
record at 2^32-1. If any record contains more than that many bytes
the table aborts hashing and throws TableFullException.
This permits the index to scan and work on files that exceed 4 GB
in size, but only if the file contains more than one unique block.
The index throws TableFullException on a 4 GB file containing all
zeros, but should succeed on a 6 GB file containing unique lines.
The index now uses a 64 bit accumulator during the common scoring

Given a 2/38 style fanout, the tree will fully load when 256 objects

Fix URIish parsing of absolute scp-style URIs
We stopped handling URIs such as "example.com:/some/p ath", because
this was confused with the Windows absolute path syntax of "c:/path".
Support absolute style scp URIs again, but only when the host name
is more than 2 characters long.

Instead work around the warning by defining our constant by
constructing it through a StringBuilder.

IndexDiff: support state [removed, untracked]
IndexDiff was extended to detect files which are both removed from the
index and untracked. Before this change these files were only added
to the removed collection.
jgit.sh <command> --help was not working for the commands Diff
and ShowCommands because of missing metaVar information. Missing
information is added here.

Implemented the git add commandline command.
Implementation delegates all work to the AddCommand class and,
therefore, supports only those options currently supported by the
AddCommand which means: --update and the filepattern... arguments.

[findBugs] Fix NP_LOAD_OF_KNOWN_NULL_VALUE
The code analyzer can't know that passing a value known to be null is
not a problem. Hence better pass null explicitly instead of the
parameters being null.

Fixed ResolveMerger regarding handling of deletions
There was a bug in ResolveMerger which is one reason for
bug 328841. If a merge was failing because of conflicts
deletions where not handled correctly. Files which have
to be deleted (because there was a non-conflicting deletion
coming in from THEIRS) are not deleted. In the
non-conflicting case we also forgot to delete the file but
in this case we explicitly checkout in the end these files
get deleted during that checkout.
This is fixed by handling incoming deletions explicitly.
Bug: 328841
