If a manifest top level directory contains '.gitmodules' we now
assume this is a git module format manifest and switch to using
that code, rather than the legacy XML based manifest.
At the same time, we move the bare repository for a project from
$TOP/.repo/projects/$REPO_PATH.git to be $REPO_NAME.git instead.
This makes it easier for us to later support a repo init from an
existing work tree, as we can more accurately predict the path of
the project's repository in the workspace. It also means that the
$TOP/.repo/projects/ directory is layed out like a mirror would be.

If the manifest format changes during init or sync we need to do
a full reparse of the manifest, and possibly allow the new object
to reconfigure the local workspace to match its expectations.

The -o option permits the user to control the name of the manifest's
remote, which normally is hardcoded to be 'origin', but can differ
because we derive it at runtime from the configuration file.

If we don't clear the cache, there can be a timestamp race between
the pickle file and the raw text file, and we may not pick up the
edit when we create a new config object around the same path name.

This permits the XML style manifest to use 'default', while other
types can use their own creation strategy for the current branch.

If the manifest is the newer SubmoduleManifest style, then the -m
option makes no sense, as you cannot select a specific file within
the current branch.

When someone copies and pastes a setup line from a web page,
they might actually copy 'repo sync' onto the clipboard and wind
up pasting it into the "Your Name" prompt. This means they will
initialize their client with the user name of "repo sync", creating
some rather funny looking commits later on. For example:
To setup your source tree:
mkdir ~/code
cd ~/code
repo init -u git://....
repo sync
If this entire block was just blindly copy and pasted into the
terminal, the shell won't read "repo sync" but "repo init" will.
By showing the user their full identity string, and asking them
to confirm it before we continue, we can give the hapless user a
chance to recover from this mistake, without unfairly harming those
who were actually named 'repo' by their parents.

This way we can use it to detect feature support in the underlying
git, such as new options or commands that have been added in more
recent versions.

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.

We now feed Project a RemoteSpec, instead of the Remote directly
from the XmlManifest. This way the RemoteSpec already has the
full project URL, rather than just the base, permitting other
types of manifests to produce the URL in their own style.

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.

If `repo start foo` fails due to uncommitted and unmergeable changes
in a single project, we have switched half of the projects over to
the new target branches, but didn't on the one that failed to move.
This change improves the situation by doing three things differently:
- We keep going when we encounter an error, so other projects
that can successfully switch still switch.
- We ignore projects whose current branch is already on the
requested name; they are logically already setup.
- We checkout the branch if it already exists, rather than
trying to recreate the branch.

On a mirror client we don't prompt for user.name,user.email as the
data is only necessary if you will make new commits. On a re-init
we were testing the command line option, not the existing IsMirror
property from the manifest configuration file.

We now correctly support re-initializing an existing client to point
to a different branch of the same manifest repository, effectively
allowing the client to switch the baseline it is operating on.

Simply setting repo.mirror true doesn't make a client into a mirror.
The on-disk layout is completely wrong for a mirror repository,
and until we fix our layout for a non-mirror client to more closely
resemble the upstream we can't do anything to easily turn on or
turn off the mirror status flag.
Signed-off-by: Shawn O. Pearce <sop@google.com>
If a client was created with "repo init --mirror" then there are
no working directories present, and no files checked out. Using
a command like "repo status" in this context makes no sense, and
actually throws back a Pytyon traceback at the console when the
underlying commands fail out.
We now tag commands with the MirrorSafeCommand type if they are
able to be executed within a mirror directory safely. Using a
command in a mirror which lacks this base class results in a
useful error letting you know the command isn't supported.

The mirror option downloads a complete forrest (as described by the
manifest) and creates a replica of the remote repositories rather
than a client working directory. This permits other clients to
sync off the mirror site.
A mirror can be positioned in a "DMZ", where the mirror executes
"repo sync" to obtain changes from the external upstream and
clients inside the protected zone operate off the mirror only,
and therefore do not require direct git:// access to the external
upstream repositories.
