Add repo sync support for GITC checkouts. If the user is in the
GITC client directory they can still pull the sources as normal
if they pass in the --force-gitc argument. Otherwise the user
should call repo sync in the GITC view to update the user's
remote view. (This works because .repo in the GITC view will
link to .repo in the client config directory.)
Part of the support for this change is the refactoring of GITC
related code into gitc_utils.py.

In some cases, a user may wish to continue with a sync even though
it would require overwriting an existing git directory. This behavior
is not safe as a default because it could result in the loss of some
user data, but as an optional flag it allows the user more flexibility.
To support this, add a --force-sync flag to the sync command that will
attempt to overwrite the existing git dir if it is specified and the
existing git dir points to the wrong obj dir.

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.

(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).

The manifest server doesn't want to have refs/heads passed to it, so
we need to strip that when the branch contains it.

Do not error if a project is missing on the filesystem, is deleted
from manifest.xml, but still exists in project.list.

This option allows the user to specify a manifest server to use when
syncing. This manifest server will provide a manifest pegging each
project to a known green build. This allows developers to work on a
known good tree that is known to build and pass tests, preventing
failed builds to hamper productivity.
The manifest used is not "sticky" so as to allow subsequent
'repo sync' calls to sync to the tip of the tree.

This bug happens when a project gets added to the manifest, and
then is renamed. Users who happened to have run "repo sync" after
the project was added but before the rename happened will try to
read the data from the old project, as the manifest was only updated
after all projects were updated successfully.
If a line is blank in project.list, its not a relevant project path,
so skip over it. Existing project.list files may have blank lines if
sync was run with no projects at all, and the file was created empty.

We have no working tree, so we cannot update the project.list
state file, nor should we try to delete a directory if a project is
removed from the manifest. Clients would still need the repository
for historical records.

After a repo sync, some of the project paths might need
to be removed. This changes maintains a list of project
paths from the previous sync operation and compares.
The revisionExpr field now holds an expression from the manifest,
such as "refs/heads/master", while revisionId holds the current
commit-ish SHA-1 of the revisionExpr. Currently that is only
filled in if the manifest points directly to a SHA-1.

Its unlikely that a new version of repo will be delivered in any
given day, so we now check only once every 24 hours to see if repo
has been updated. This reduces the sync cost, as we no longer need
to contact the repo distribution servers every time we do a sync.
repo selfupdate can still be used to force a check.

We now try to sync all projects that can be done safely first, before
we start rebasing user commits over the upstream. This has the nice
effect of making the local tree as close to the upstream as possible
before the user has to start resolving merge conflicts, as that extra
information in other projects may aid in the conflict resolution.
Informational output is buffered and delayed until calculation for
all projects has been done, so that the user gets one concise list
of notice messages, rather than it interrupting the progress meter.
Fast-forward output is now prefixed with the project header, so the
user can see which project that update is taking place in, and make
some relation of the diffstat back to the project name.
Rebase output is now prefixed with the project header, so that if
the rebase fails, the user can see which project we were operating
on and can try to address the failure themselves.
Since rebase sits on a detached HEAD, we now look for an in-progress
rebase during sync, so we can alert the user that the given project
is in a state we cannot handle.

Users may want to upgrade only repo to the latest release, but
leave their working tree state alone and avoid 'repo sync'.

This way users can see how much is left during fetch. Its
especially useful when most syncs are no-ops but there are
hundreds of repositories to poll.

This permits usage of 'repo sync' while offline, as we bypass the
network based portions of the code and do only the local sync.
An example use case might be:
repo sync -n ; # while we have network
... some time later ...
repo sync -l ; # while without network, come up to date

The -d flag moves the project back to a detached HEAD state,
matching what is listed in the manifest. This can be useful to
set a client to something stable (or at least well-known), such as
before a sequence of 'repo download' commands are used to get some
changes for testing.

This makes it easier to update all repositories, without actually
impacting the working directory, or learning about how to use
`repo forall -c 'git fetch $REPO_REMOTE' `.
