I'm considering this default behavior as a bug for normalmode.  The
creation of a repository via a read activity seems far too accidental
for my taste.  Repositories are created by pushing to them.

This does mean that:

    git clone <new-url>
    ...
    git push

is no longer a shorthand for:

    git init
    git remote add origin <new-url>
    ...
    git push

I'm ok with that.

Since it is now allowed to remove the remote default branch, this script
needs to handle cases where there are no branches following a push.

In this case, the `git symbolic-ref` command will fail, and we return
our standard warning for when HEAD is dangling.

The new installation procedure is to start with ./configure to set your
pubkey up for admin access.  The initialize script is updated to use an
active prompt, since as-is, CTRL-C won't properly terminate the script
to cancel.

Port the cgit docker image to build from Alpine Linux, and finish the
file tree clean up started by the previous merge.

* cgit-alpine-port:
  cgit: Update SSH clone URLs
  cgit: Update scan-path / repository mount location
  cgit: Update user and file paths for alpine distro
  cgit: Port Dockerfile for alpine base
  cgit: Consolidate config files into a single directory

The username used to access gitolite has changed from 'gitolite' to
'git'.  Reflect this in the cgit UI.

Since the data volume now only contains git repositories, rather than
the whole gitolite host home directory, there is no need to mount to a
nested path.  Anticipate moving the mount point, and change the cgit
scan path to /repositories.

Move the cgit image off of archlinux for the same reasons as gitolite.
However, in this case, debian isn't necessary, and going with alpine
will give even smaller images.  As is, it seems simpler to port the
config files over to alpine anyway.
