This fixes intermingling of parallel jobs and simplifies the code
by switching to subprocess.run. This also provides stable output
in the order of projects by returning the output as a string that
the main loop outputs.
This drops support for interactive commands, but it's unclear if
anyone was relying on that, and the default behavior (-j2) made
that unreliable. If it turns out someone still wants this, we can
look at readding it.

The status command runs a bunch of jobs in parallel, and each one
is responsible for writing to stdout directly. When running many
noisy jobs in parallel, output can get intermingled. Pass down a
StringIO buffer for writing to so we can return the entire output
as a string so the main job can handle displaying it. This fixes
interleaved output as well as making the output stable: we always
display results in the same project order now. By switching from
map to imap, this ends up not really adding any overhead.

Currently we don't have a way for the checked out repo version to
declare the version of tools it needs before we start running it.
For somethings, like git, it's not a big deal as it can handle all
the asserts itself. But for things like Python, it's impossible
to reliably check before executing.
We're in this state now:
- we've been allowing Python 3.4, so the launcher accepts it
- the repo codebase starts using Python 3.6 features
- launcher tries to import us but hits syntax errors
- user is left confused and assuming new repo is broken because
they're seeing syntax errors
This scenario is playing out with old launchers that still accept
Python 2, and will continue to play out as time goes on and we want
to require newer versions of Python 3.
Lets create a JSON file to declare all these system requirements.
That file format is extremely stable, so loading & parsing from
even ancient versions of Python shouldn't be a problem. Then the
launcher can read these settings and check the system state before
attempting to execute any code. If the tools are too old, it can
clearly diagnose & display information to the user as to the real
problem (and not emit tracebacks or syntax errors).
We have a couple of different tool version checks already (git,
python, ssh) and can harmonize them in a single place.
This also allows us to assert a reverse dependency if the need
ever comes up: force the user to upgrade their `repo` launcher
before we'll let them run us. Even though the launcher warns
whenever a newer release is available, some users seem to ignore
that, or they don't use repo that often (on the scale of years),
and their upgrade jump is so dramatic that they fall back into
the syntax error pit.
Hopefully by the end of the year we can assume enough people
have upgraded their launcher such that we can delete all of the
duplicate version checks in the codebase. But until then, we'll
keep them to maintain coverage.

* Ubuntu Trusty: released Apr 2014, EOL Apr 2022
* Debian Jessie: released Apr 2015, EOL Jun 2020
So the min required distros would now be:
* Ubuntu Xenial: released Sep 2015 w/Python 3.5
* Debian Stretch: released Jun 2017 w/Python 3.6
I don't think we're quite ready to drop Python 3.5 which would affect
Ubuntu Xenial -- we'd have to update to Ubuntu Bionic from Apr 2018.
Let's see how much the community reacts to loss of Python 3.4 first.

Ways to enable logging:
1) Set git's trace2.eventtarget config variable to desired logging path
2) Specify path via --git_trace2_event_log option
A unique logfile name is generated per repo execution (based on the repo session-id).
Testing:
1) Verified git config 'trace2.eventtarget' and flag enable logging.
2) Verified version/start/end events are expected format:

3) Unit tests

We don't support Python 2 anymore, so stop allowing it to fallback.
If we try to run the latest version with Python 2, it just hits
syntax errors which confuses people. Dump a clear error message
that their system is too old and give up.

The codebase still supports Python 3.5, so allow use of that instead
of requiring Python 3.6+. Supporting this mode well is a bit tricky
as we want to first scan for newer versions before falling back to
older ones. And we have to avoid infinite loops in the process.

When checkout is done with Git worktrees then the HEAD in the
bare-git repositories point to the initialized default (e.g.
'refs/heads/master'). This default branch does not exist
locally and is not automatically created.
When a user now creates a branch in any git repository named
'master' then it is no longer possible to get rid of this branch,
neither is it possible to switch to another branch and switch
back to this master branch. Git concludes the 'master' branch is
already checked out (in the bare Git) and that results in a
lockdown of this master branch.
To repoduce this issue, run these commands in a repo tree
checked out with --worktree:
- git checkout master # assuming the remote repo has a master branch,
# a local tracking branch master is created here
- git checkout -b temp
- git checkout master # This one now fails
- git branch -d master # fails too
The failure is caused by Git assuming the master branch is checked out
by the bare git repository since HEAD is pointing towards it.
To workaround this, we always detach HEAD in the bare-git when
syncing. We don't need it to point to a ref in general, but we
would like it to be valid so git tools "just work" if they're run
in here.
