share: make it possible to control the working copy format variant

A share will use the same format as its source for the store, but there are no
reason to not lets it control the working copy variant at creation time.

So we make it so.

This test tries to exercise the ssh functionality with a dummy script

creating 'remote' repo

  $ hg init remote
  $ cd remote

Make sure hg is really paranoid in serve --stdio mode. It used to be
possible to get a debugger REPL by specifying a repo named --debugger.
  $ hg -R --debugger serve --stdio
  abort: potentially unsafe serve --stdio invocation: ['-R', '--debugger', 'serve', '--stdio']
  [255]
  $ hg -R --config=ui.debugger=yes serve --stdio
  abort: potentially unsafe serve --stdio invocation: ['-R', '--config=ui.debugger=yes', 'serve', '--stdio']
  [255]
Abbreviations of 'serve' also don't work, to avoid shenanigans.
  $ hg -R narf serv --stdio
  abort: potentially unsafe serve --stdio invocation: ['-R', 'narf', 'serv', '--stdio']
  [255]
#else
rhg aborts early on -R without a repository at that path
  $ hg -R --debugger serve --stdio

  abort: repository --debugger not found (known-bad-output !)

  $ hg -R --config=ui.debugger=yes serve --stdio
  abort: potentially unsafe serve --stdio invocation: ['-R', '--config=ui.debugger=yes', 'serve', '--stdio'] (missing-correct-output !)

  abort: potentially unsafe serve --stdio invocation: ['-R', 'narf', 'serv', '--stdio'] (missing-correct-output !)

If the repo does exist, rhg finds an unsupported command and falls back to Python
which still does the right thing
