Adds the new gitc-init command to set up a GITC client. Gitc-init
sets up the client directory and calls repo init within it. Once
the repo is initialized, then generates a GITC manifest file
by using git ls-remote on each project and retrieving the HEAD SHA
to use as the revision attribute.
Gitc-init inherits from and has all the options as repo init.

For projects that have been cloned outside of the repo command (or
cloned a long time ago), commit abaa7f312f
introduced an error message to invite the user to use --force-sync.
However, due to the risk of data loss, it's useful to know which
project's git directory is being replaced before deciding whether or not
to provide --force-sync.
This change updates the exception's associated value to include the
project's relative path and explain to the user how they can resolve the
issue. A previous version of this commit used the project name. However,
for projects that have multiple work trees, the name can be ambiguous,
while the path clearly identifies which git directory will be replaced.

The existing code here makes sure that switching clone-depth from on to
off actually causes the history to be fully restored. Unfortunately, it
does this by fetching the full history every time the fetch spec
changes. Switching between two clone-depth="1" branches will fetch far
more than the top commit.
Instead, when not using clone-depth, pass --depth=2147483647 to git
fetch so that it ensures that we have the entire history. That is
slightly less efficient, so limit it to only when there are shallow
objects in the project by checking for the existance of the 'shallow'
file.

Previously repo would only print the failing project path if
Sync_NetworkHalf returned false/empty, but if it threw an
exception the print() was never called.

This fixes these errors:
...
File ".repo/repo/project.py", line 2371, in _ReferenceGitDir
os.symlink(os.path.relpath(src, os.path.dirname(dst)), dst)
OSError: [Errno 17] File exists
Which was happening for checkouts that were created before v1.12.8, when
project-objects was created. Nothing had yet been forcing these
checkouts to use project-objects, until the recent verification changes.
In this OSError case, we already created the symlink, so src == dst, and
the directory did not exist. This caused us to run os.makedirs the
os.symlink on the same file.
dst really should be the file in gitdir, not the target of that symlink
if it exists. So just use realpath for the dotgit portion of the path.

Enable operating against groups of repositories. As it stands, it isn't
compatible with `-r/--regex`.
`repo forall -g groupname -c pwd` will run `pwd` for all projects in
groupname.
`repo forall -g thisgroup,-butnotthisone -c pwd` will run `pwd` for all
projects in `thisgroup` but not `butnotthisone`.
`repo list -g groupname -n` will list all the names of repos in
`groupname`.

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.

If _InitGitDir fails, it leaves any progress it had made on the file
system. This can cause subsequent calls to repo sync to behave
differently. This is especially evident when _CheckDirReference() fails,
since it will not be invoked when sync is retried because both the
source and destination directories already exist.
To address this, have _InitGitDir() clean up any directories it has created
if it catches an exception. Also behave the same way for _InitWorkTree().

For some users it is not desirable to remove refs that don't exist
on the remote server when syncing a mirror repo.
This reverts commit b4d43b9f66.

The fetch logic for the case where depth is set and revision is a
SHA1 has several failure modes that are not handled well by the
current logic.
1) 'git fetch <SHA1>' requires git version >= 1.8.3
2) 'git fetch <SHA1>' can be prevented by a configuration option on the server.
3) 'git fetch --depth=<N> <refspec>' can fail to contain a SHA1 specified by
the manifest.
Each of these cases cause infinite recursion when _RemoteFetch() tries to call
itself with current_branch_only=False because current_branch_only is set to
True when depth != None.
To try to prevent the infinite recursion, we set self.clone_depth to None
before the first retry of _RemoteFetch(). This will allow the Fetch to
eventually succeed in the case where clone-depth is specified in the manifest.
A user specified depth from the init command will still recurse infinitely.
In addition, never try to fetch a SHA1 directly if the git version being used
is not at least 1.8.3.

* changes:
forall: use smart sync override manifest if it exists
sync: Remove smart sync override manifest when not in smart sync mode
forall: Don't try to get lrev of projects in mirror workspace
sync: Improve error message when writing smart sync manifest fails
Previously, in running the `manifest` command, we wouldn't output the
upstream if the default upstream would include the pinned sha1.
However, now that fetching refs/heads/* doesn't guarantee that we will
have the sha1, we need to always output the specified upstream branch.

If a workspace is synced with the -s or -t option, the included projects
may be different to those in the original manifest. However, when using
the forall command, the list of the projects from the original manifest
is used.
If the smart sync manifest file exists, use it to override the original
manifest.

When syncing with the -s or -t option, a smart_sync_override.xml file
is created. This file is left in the file system when syncing again
without the -s or -t option.
Remove the smart sync override manifest, if it exists, when not using
the -s or -t option.

git rev-parse fails for projects that don't have an explicit revision
specified, and don't have a branch of the same name as the default
revision. This can be the case in a workspace synced with the smart
sync (-s) or smart tag (-t) option.

After performing the actual cherry-pick operation, the code
in cherry_pick.py opens a pipe to 'git commit -F' to rewrite the commit
message, emits the fixed-up commit msg to the pipe, then waits
for 'git commit' to complete. The child 'git' process winds up
hanging while reading from the pipe, however, since the parent
process still has it open. To fix the hang, change the parent process
to close its end of the pipe after it has emitted the message.

This allows a project to use globs in the linkfile src attribute. When
a glob is used in the src the dest field must be a directory. Then
_LinkFile._Link(self) calls will create symbolic links in the dest
directory to all of the entries in the src as defined by the glob
specification.
Below all of the entries in master-configs/ will have symbolic links
in <root dir>/configs directory:
<project name="helloworld.git" path="apps/helloworld">
<linkfile src="master-configs/*" dest="configs"/>
</project>

The source (target) of the symlink is specified relative to a project
within a tree, and the destination is specified relative to the top
of the tree, so it should always be possible to create a relative symlink
to the target file. Relative symlinks will allow moving an entire tree
without breaking the symlink, and copying a tree (with -p) without leaving
a symlink to the old tree.

There are a set of cases that can cause the git directory in
.repo/projects to point to a directory in .repo/project-objects that
is not the one specified in the manifest. This results in a tree that
is not sane, and so should cause a failure.
In order to reproduce the failure case:
1) Sync to any manifest
2) Change the 'name' of a project to a different repository. Leave the
'path' the same.
3) Resync the modified project. The project-objects directory will not
be created, and the projects directory will remain pointed at the old
project-objects.

In 2fb6466f79 an optimisation was
added to avoid fetching from remotes if the project is fixed to
a revision and the revision is already available locally.
This causes problems for users who expect all objects to be
fetched by default.
Change the logic so that the optimized behaviour is only enabled if
an option is explicitly given to repo sync.
