Make it explicit that the ssh wrapper we use for control master
support accepts OpenSSH-compatible command line arguments instead of
asking Git to guess.
The GIT_SSH_VARIANT setting was introduced in Git v2.13.0-rc0~3^2~2
(2017-02-01) as a more reliable detection method than relying on the
ssh command name. Fortunately the default variant was 'ssh' (i.e.,
OpenSSH-compatible) so this wasn't initially required.
Now Git wants to start using more OpenSSH features
(-o SendEnv=GIT_PROTOCOL), and in order to do so its ssh variant
detection will need to be tweaked. Set GIT_SSH_VARIANT explicitly
so this helper can continue to work regardless of how Git modifies
its autodetection.

Python on Windows does not support non blocking file operations.
To workaround this issue, we instead use Threads and a Queue to
simulate non-blocking calls. This is happens only when running
with the native Windows version of Python, meaning Linux and Cygwin
are not affected by this change.

See git commit 33cfccbbf35a -- some protocols allow arbitrary command
execution as part of the URL. Instead of blindly allowing those,
whitelist the allowed URL protocols unless the user has already done so.

output from a process is in bytes in python3. we need
to decode it.
in Python3, bytes don't have an encode attribute. use this
to identify it.

Switch the GitCommand program to always capture the output for stdout
and stderr. And by default print the output while running.
The options capture_stdout and capture_stderr have effectively become
options to supress the printing of stdout and stderr.
Update the 'git fetch' to use '--progress' so that the progress messages
will be displayed. git checks if the output location isatty() and if it
is not a TTY it will by default not print the progress messages.

'repo' and 'git_command.py' had their own git version parsing code.
This change shares that code between the modules. DRY is good.

The last change regarding version parsing lost handling of version
hyphenation, this restores that. In otherwords,
1.1.1-otherstuff is parsed as (1,1,1) instead of (1,1,0)

"except Exception as e" instead of "except Exception, e"
This is part of a transition to supporting Python 3. Python >= 2.6
support "as" syntax.
Note: this removes Python 2.5 support.

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.

Communication via pipes to sub processes is done by calling
communicate(). This will make repo not hang every now and

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

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.

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.
