An HTTP (or HTTPS) based remote server may now offer a 'clone.bundle'
file in each repository's Git directory. Over an http:// or https://
remote repo will first ask for '$URL/clone.bundle', and if present
download this to bootstrap the local client, rather than relying
on the native Git transport to initialize the new repository.
Bundles may be hosted elsewhere. The client automatically follows a
HTTP 302 redirect to acquire the bundle file. This allows servers
to direct clients to cached copies residing on content delivery
networks, where the bundle may be closer to the end-user.
Bundle downloads are resumeable from where they last left off,
allowing clients to initialize large repositories even when the
connection gets interrupted.
If a bundle does not exist for a repository (a HTTP 404 response
code is returned for '$URL/clone.bundle'), the native Git transport
is used instead. If the client is performing a shallow sync, the
bundle transport is not used, as there is no way to embed shallow
data into the bundle.

Teach repo how to resolve URLs using the url.insteadof feature
that C Git natively uses during clone, fetch or push. This will
later allow repo to resolve a URL before accessing it directly.
We do not want to pre-resolve things and store the resolved URL
into individual projects, as this makes it impossible for the
user to undo the insteadof mapping at a later date.

(cherry picked from commit d2dfac81ad)
This fixes the SSH Control Masters to be managed in a thread-safe
fashion. This is important because "repo sync -jN" uses threads to
sync more than one repository at the same time. The problem didn't
show up earlier because it was masked if all of the threads tried to
connect to the same host that was used on the "repo init" line.
os.remove() raises OSError if the file being removed doesn't exist.
Check before calling to ensure we don't raise a useless exception
on an already deleted file.

If the SSH control master process is killed while an active git
fetch is using its network socket, the underlying SSH client may
not realize the connection was broken. This can lead to both the
client and the server waiting indefinitely for network messages
which will never be sent.
Work around the problem by keeping track of any processes that use
the tunnels we establish. If we are about to kill any of the SSH
control masters that we started, ensure the clients using them are
successfully killed first.

Its quite common for most projects to be matching the current
manifest revision, as most developers only modify one or two projects
at any one time. We can speed up `repo start foo` (that impacts
the entire client) by performing most of the branch creation and
switch operations in pure Python, and thus avoid 4 forks per project.

We now cache the output of `git config --list` for each of our
GitConfig instances in a Python pickle file. These can be read
back in using only the Python interpreter at a much faster rate
than we can fork+exec the git config process.
If the corresponding git config file has a newer modification
timestamp than the pickle file, we delete the pickle file and
regenerate it. This ensures that any edits made by the user
will be taken into account the next time we consult the file.
This reduces the time for a no-op repo sync from 0.847s to 0.269s.

If the user has multiple projects to upload changes to, and they

If /ssh_info is protected by an HTML based login page, we may get
back a "200 OK" response from the server with some HTML document
asking us to authenticate. This can't be parsed into a host name
and port number, so we shouldn't even try.
Valid host names and decimal port numbers cannot contain '<', but
an unexpected HTML login page would. So we test for '<' to give
us a fair indicator that the content isn't what we think it is,
and bail out.

If a review URL is set to 'http://host/Gerrit' because the user
thinks that is the correct way to point repo at Gerrit, we should

Likewise, if a review URL points already at '/ssh_info' for a Gerrit

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.
