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.

If the user has disabled a prompt, skip the two commands we use to
obtain the list of commits and the date of the branch. These will
never be displayed and just waste the end-user's time.

If review.URL.autoupload is set to true in a project's .git/config
or in ~/.gitconfig then `repo upload` will automatically upload,
and skip prompting the end-user.
Conversely, if review.URL.autoupload is set to false, then repo
will refuse to upload to that project.

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 there is nothing output at all, tell the user the working tree is

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.

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.

Modern Gerrit2 automatically outputs the URL for each commit to
stderr as it creates the records. Dumping the URL ourselves is
unnecessary additional output, and worse is just an approximate

hostname for web connections than what is listed in the manifest.

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

This can be useful to create a new manifest from an existing client,
especially if the client wants to use the "-r" option to set each
project's revision to the current commit SHA-1, making a sort of a
tag file that can be used to recreate this exact state elsewhere.

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.

REPO_PATH is the path relative the the root of the client.
REPO_REMOTE is the name of the remote system from the manifest.
REPO_LREV is the name of the revision from the manifest, but
translated to something the local repository knows.
REPO_RREV is the name of the revision from the manifest.
This allows us to do commands like:
repo forall -c 'echo "(cd $REPO_PATH && git checkout `git rev-parse HEAD`)"'

Users are prompted with the list of known changes we are about
to upload, and they can fill out the current change numbers for
any changes which already exist in the data store. For each of
those changes the change number and commit id is sent as part of
the upload request, so Gerrit can insert the new commit as a new
patch set of the existing change, rather than make a new change.
This facility permits developers to replace a patch so they can
address comments made on a prior version of the same change.

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.

This hook is evaluated by `git gc --auto` to determine if it is a
good idea to execute a GC at this time, or defer it to some later
date. When working on a laptop its a good idea to avoid GC if you
are on battery power as the extra CPU and disk IO would consume a
decent amount of the charge.
The hook is the standard sample hook from git.git contrib/hooks,
last modified in git.git by 84ed4c5d117d72f02cc918e413b9861a9d2846d7.
I added the GPLv2 header to the script to ensure the license notice
is clear, as it does not match repo's own APLv2 license.
We only update hooks during initial repository creation or on
a repo sync. This way we don't incur huge overheads from the
hook stat operations during "repo status" or even the normal
"repo sync" cases.

Now that repo relies only on the git data stream (as it is much
faster to download through) we don't really need to be parsing the
<snapshot> elements within manifest. Its a lot of complex code to

just aren't calling it anymore.

Now `repo download . 1402` would download the change numbered 1402
into the current project and check it out for the user, using a
detached HEAD. `repo sync .` would back out of the change and
return to the upstream version.
Multiple projects can be fetched at once by listing them out on
