[EGIT PATCH 00/23] Push implementation

[Marek Zawirski <marek.zawirski@gmail.com>]

Finally, series with push implementation. It has taken a "while" to
squash all bugs this time and polish the series, uhh.

Part of this series is signifficant refactor of .transport package to
support code reuse between fetch and push implementations + minor
fixes/improvements.

Needed push operation elements were created. Implementation provides
basis for different push protocols by common push process and its
dendendencies. Push over git-receive-pack based transports is
implemented. 
Shawn is now working on support for push over less git-inteligent
protocols. I'm moving into GUI stuff.

Beside of JUnit test cases for (IMO) 2 most complex classes that
revealed few bugs, I've tested manually pgm.Push extensively. 
Each protocol (SSH, local, git-daemon) was tested at least 1 time.


So now I can say, that this branch is available on 
http://repo.or.cz/w/egit/zawir.git?a=shortlog;h=refs/heads/push
and it was pushed with jgit push! :) Yeah!
It is based (together with packwriter stuff, not old packwrite branch)
on egit's master: 4cf736fdf3.

BTW, in case of any comments, requests, please consider that I'm
semi-off-line next ~2,5weeks, I can sync my laptop each few days,
but certainly not everyday.

PS I saw that Shawn's sftp-push branch also contains new 
TransportException constructors conversion, so we may have to 
resolve this duplication, I added it as last commit.

Marek Zawirski (23):
