This implements the git send-pack command and refactors "git push"
to use the send-pack plumbing rather than the hack which was previously in place to
allow pushing in the early days of dgit. The result should
be that it will work with all transport protocols that are
supported, and not just HTTP.
It also splits the push command into the same git/cmd package
distinction for parsing command line and implementing the logic
as other commands use instead of all being done in cmd.
(Another leftover from the fact that push was one of the earliest
things implemented in dgit.) In doing so, it brings the behavior of
push closer in line with that of the official git client. (ie now
the remote name is required, not the branch name, it can be called
with no arguments, and --force is no longer implied.)
Also fixes a bug where Linux wasn't loading SSH keys because of
incorrect build tags.
