A common pattern in our subcommands is to verify the arguments &
options before executing things. For some subcommands, that check
stage is quite long which makes the execution function even bigger.
Lets split that logic out of the execute phase so it's easier to
manage these.
This is most noticeable in the sync subcommand whose Execute func
is quite large, and the option checking makes up ~15% of it.
The manifest command's Execute can be simplified significantly as
the optparse configuration always sets output_file to a string.

People seem to not expect the sync process to halt immediately if an
error is encountered. It's also basically guaranteed to leave their
tree in an incomplete state. Lets invert the default behavior so we
attempt to sync (both fetch & checkout) all projects. If an error is
hit, we still exit(1) and show it at the end.
If people want the sync to abort quickly, they can use the new option
--fail-fast.

As we convert repo to support Python 3, the version of Python that we
use might not be the version that repo hooks users have written for.
Since repo upgrades are not immediate, and not easily under direct
control of end users (relative to the projects maintaining the hook
code), allow hook authors to declare the version of Python that they
want to use.
Now repo will read the shebang from the hook script and compare it
against the version of Python repo itself is running under. If they
differ, we'll try to execute a separate instance of Python and have
it load & execute the hook. If things are compatible, then we still
use the inprocess execution logic that we have today.
This allows repo hook users to upgrade on their own schedule (they
could even upgrade to Python 3 ahead of us) without having to worry
about their supported version being exactly in sync with repo's.

Switch to using .items() instead of .iteritems(). Python 3 doesn't
have .iteritems() as .items() is a generator, and these are small
enough that the Python 2 overhead should be negligible.
We have to run .keys() through list() in a few places as Python 3

This was fixed in I091ff37998131e2e6bbc59aa37ee352fe12d7fcd to
automatically disable this smudge filter. However, later versions of
Git (2.11.0) introduced a new filter protocol [1], to avoid spawning
a new command for each filtered file. This was implemented in Git-LFS
1.5.0 [2].
This patch fixes the issue by setting the git lfs process filter, in
addition to the smudge filter. For any projects that have LFS objects,
`git lfs pull` must still be executed manually afterwards.
