Ancient versions of Git don't understand the -c command line flag
that we tried to use to pass http_proxy down into Git on Darwin.
Use the environment variable instead, to more gracefully degrade
with these old versions.

The system libcurl library seems to ignore http_proxy on Mac OS
X systems. Copy the http_proxy environment variable (if set) as
`git -c http.proxy` whenever running a Git command.

Make repo use the standard way in python to work with pipes.
Communication via pipes to sub processes is done by calling
communicate(). This will make repo not hang every now and
then.

Setting REPO_CURL_VERBOSE=1 in the environment will register a debug
level HTTPHandler on the urllib2 library, showing HTTP requests and
responses on the stderr channel of repo.
During any HTTP or HTTPS request created inside of the repo process,
a custom User-Agent header is now defined:
User-Agent: git-repo/1.7.5 (Linux) git/1.7.7 Python/2.6.5

Windows allows the environment to have unicode values.
This will cause Python to fail to execute the command.

If the SSH control master process is killed while an active git
fetch is using its network socket, the underlying SSH client may
not realize the connection was broken. This can lead to both the
client and the server waiting indefinitely for network messages
which will never be sent.
Work around the problem by keeping track of any processes that use
the tunnels we establish. If we are about to kill any of the SSH
control masters that we started, ensure the clients using them are
successfully killed first.

This way we can use it to detect feature support in the underlying
git, such as new options or commands that have been added in more
recent versions.

Mac OS X sets TMPDIR to a very long path within /var, so long
that a socket created in that location is too big for a struct
sockaddr_un on the platform, resulting in OpenSSH being unable
to create or bind to a socket in that location.
Instead we try to use the very short and very common /tmp, but
fall back to the guessed default if /tmp does not exist.

By creating a background ssh "control master" process which lives
for the duration of our sync cycle we can easily cut the time for
a no-op sync of 132 projects from 60s to 18s.

The value of the varible TRACE was copied during the import, which
happens before the --trace option can be processed. So instead we
now use a function to determine if the value is set, as the function
can be safely copied early during import.
