This significantly reduces sync time and used brandwidth as only
a tar of each project's revision is checked out, but git is not
accessible from projects anymore.
This is relevant when git is not needed in projects but sync
speed/brandwidth may be important like on CI servers when building
several versions from scratch regularly for example.
Archive is not supported over http/https.

It is often useful to be able to include the same project more than
once, but with different branches and placed in different paths in the
workspace. Add this feature.
This CL adds the concept of an object directory. The object directory
stores objects that can be shared amongst several working trees. For
newly synced repositories, we set up the git repo now to share its
objects with an object repo.
Each worktree for a given repo shares objects, but has an independent
set of references and branches. This ensures that repo only has to
update the objects once; however the references for each worktree are
updated separately. Storing the references separately is needed to
ensure that commits to a branch on one worktree will not change the
HEAD commits of the others.
One nice side effect of sharing objects between different worktrees is
that you can easily cherry-pick changes between the two worktrees
without needing to fetch them.

This was broken in b2bd91c, which updated the manifest after it had

not the one from the manifest server).
This builds on 0766900 and overrides the manifest by the one

Add a new module with methods for checking the Python version.
Instead of handling Python3 imports with try...except blocks, first
check the python version and then import the relevant modules. This
makes the code a bit cleaner and will result in less diff when/if we
remove support for Python < 3 later.
Use the same mechanism to handle `input` vs. `raw_input` and add
suppression of pylint warnings caused by redefinition of the built-in
method `input`.

Several messages are printed with the `print` method and the message
is split across two lines, i.e.:
print('This is a message split'
'across two source code lines')
Which causes the message to be printed as:
This is a message splitacross two source code lines
Add a space at the end of the first line before the line break:
print('This is a message split '
'across two source code lines'

If the current manifest is broken then "repo sync" fails because it
can't retrieve the default value for --jobs. Use 1 in this case, in
order that you can "repo sync" to get a fixed manifest (assuming someone
fixed it upstream).

(Previous submission of this change broke Android buildbot due to
incorrect regular expression for parsing git-config output. During
investigation, we also found that Android, which pulls Chromium, has a
workaround for Chromium's submodules; its manifest includes Chromium's
submodules. This new change, in addition to fixing the regex, also
take this type of workarounds into consideration; it adds a new
attribute that makes repo not fetch submodules unless submodules have a
project element defined in the manifest, or this attribute is
overridden by a parent project element or by the default element.)
We need a representation of git-submodule in repo; otherwise repo will
not sync submodules, and leave workspace in a broken state. Of course
this will not be a problem if all projects are owned by the owner of the
manifest file, who may simply choose not to use git-submodule in all
projects. However, this is not possible in practice because manifest
file owner is unlikely to own all upstream projects.
As git submodules are simply git repositories, it is natural to treat
them as plain repo projects that live inside a repo project. That is,
we could use recursively declared projects to denote the is-submodule
relation of git repositories.
The behavior of repo remains the same to projects that do not have a
sub-project within. As for parent projects, repo fetches them and their
sub-projects as normal projects, and then checks out subprojects at the
commit specified in parent's commit object. The sub-project is fetched
at a path relative to parent project's working directory; so the path
specified in manifest file should match that of .gitmodules file.
If a submodule is not registered in repo manifest, repo will derive its
properties from itself and its parent project, which might not always be
correct. In such cases, the subproject is called a derived subproject.
To a user, a sub-project is merely a git-submodule; so all tips of
working with a git-submodule apply here, too. For example, you should
not run `repo sync` in a parent repository if its submodule is dirty.

Try to more accurately estimate which projects take the longest to
sync by keeping an exponentially weighted moving average (a=0.5) of
fetch times, rather than just recording the last observation. This
should discount individual outliers (e.g. an unusually large project
update) and hopefully allow truly slow repos to bubble to the top.
Change-Id: I72b2508cb1266e8a19cf15b616d8a7fc08098cb3
Some projects may consistently take longer to fetch than others, for
example a more active project may have many more Gerrit changes than a
less active project, which take longer to transfer. Use a simple
heuristic based on the last fetch time to fetch slower projects first,
so we do not tend to spend the end of the sync fetching a small number
of outliers.
This algorithm is probably not optimal, and due to inter-run latency
variance and Python thread scheduling, we may not even have good
estimates of a project sync time.

The threaded 'repo sync' implementation would very often freeze the
process when interrupted by the user with Ctrl-C. The only solution
being to kill -9 the process explicitly from another terminal.
The reason for this is best explained here:
http://snakesthatbite.blogspot.fr/2010/09/cpython-threading-interrupting.html
This patch makes all helper sync threads 'daemon', which allows the
process to terminate immediately on Ctrl-C.
Note that this will forcefully kill all threads in case of interruption; this
is generally a bad thing, but:
1/ This is equivalent to calling kill -9 in another terminal, which
is the _only_ thing that can currently stop the process.
2/ There doesn't seem to be a way to tell the worker threads to
gently stop when they are in a blocking operation anyway (even
in the non-threaded case).
+ Do the same for "repo status -j<count>".
