In order to better analyze and track repo errors, repo command failures
need to be tied to specific errors in repo source code.
Additionally a new GitCommandError was added to differentiate between
general git related errors to failed git commands. Git commands that opt
into verification will raise a GitCommandError if the command failed.
The first step in this process is a general error refactoring

In order to stop sharing objects/ directly between shared projects,
we have to fetch the remote objects into project-objects/ manually.
So instead of running git operations in the individual project dirs
and relying on .git/objects being symlinked to project-objects/,
tell git to store any objects it fetches in project-objects/.
We do this by leveraging the GIT_OBJECT_DIRECTORY override. This
has been in git forever, or at least since v1.7.2 which is what we
already hard require. This tells git to save new objects to the
specified path no matter where it's being run otherwise.
We still otherwise run git in the project-specific dir so that it
can find the right set of refs that it wants to compare against,
including local refs. For that reason, we also have to leverage
GIT_ALTERNATE_OBJECT_DIRECTORIES to tell git where to find objects
that are not in the upstream remote. This way git doesn't blow up
when it can't find objects only associated with local commits.
As it stands right now, the practical result is the same: since we
symlink the project objects/ dir to the project-objects/ tree, the
default objects dir, the one we set $GIT_OBJECT_DIRECTORY to, and
the one we set $GIT_ALTERNATE_OBJECT_DIRECTORIES to are actually
all the same. So this commit by itself should be safe. But in a
follow up commit, we can replace the symlink with a separate dir
and git will keep working.

Repo will remember a choice and an expiration time of the choice, per
user, about whether to use superproject by default. When not specified
from command line and the choice is not expired, repo would use the
user default value.
When a user default value is not present and when the system wide
enable default is provided in git's system configuration, repo would
ask the user for a confirmation which will be valid for two weeks.
git_config.py: Add support for system config. When reading system
config, we would use --system to avoid hardcoding a path as the
value may be different on some other distributions.
git_superproject.py: Add a new subroutine, _UseSuperproject(), which
returns whether superproject should be used and whether it
is from a user configuration.
The value is determined in the following order:
1. If the user specifies either --use-superproject or
--no-use-superproject, then that choice is being used.
2. If neither is specified, we would then check the saved value
(upon repo init) and use that choice when there was a choice.
3. We then check if there is a saved and unexpired value for
user's choice in their ~/.gitconfig, and use the unexpired
choice, if available.
4. Finally, if all the above didn't give us a decision, and if
the git system configuration is providing a rollout hint, present
a prompt to user for their decision and save it in ~/.gitconfig.
subcmds/sync.py: Make use of the new UseSuperproject() provided by
git_superproject.py.

Different Python & OS versions have different environ behavior wrt
accepted types & encoding. Since we're migrating to be Python 3 only,
lets change our code to assume strings always work as that's what the
newer Python 3 does. This will fail under Python 2 for some env vars,
mostly on Windows, but the effort of maintaining shim layers that can
handle these edge cases isn't worth it when we're dropping that code.
We leave the logic in the `repo` launcher for now as it is simple, and
we want it to be able to switch versions a bit longer than the rest of
the tree.
Here's the support table:
| *NIX | Windows |
Python 2 | ASCII string | str or bytes, not unicode |
Python 3 | str or bytes | str only |
Windows uses strings natively in its environment all the time. But it
doesn't allow unicode strings under Python 2, so we have to encode.
Python 2 on *NIX is funky in that it always lowers to ASCII, so we had
to manually encode to avoid errors regardless of unicode or str.
Python 3 on Windows & *NIX will accept strings. *NIX will also accept
bytes but Windows will not.

We were perhaps a bit too hasty to jump to git-2.10. Existing LTS
releases of Ubuntu are quite old still: Trusty has 1.9 while Xenial
has 2.5. While we plan on dropping support for those eventually as
we migrate to Python 3.6, we don't need to be so strict just yet on
the git versions.
We also want to disconnect the version the repo launcher requires
from the version the rest of the source tree requires. The repo
launcher doesn't need as many features, and being flexible there
allows us more freedom to upgrade & rollback as needed.
So we'll allow git-1.7 again, but start warning on any users older
than git-1.9. This aligns better with existing LTS releases, and
gives users a chance to start upgrading before we cut them off.

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.
