introduce new RequirementError (issue2649)

This improves the misleading error message

  $ hg identify
  abort: there is no Mercurial repository here (.hg not found)!

to the more explicit

  $ hg identify
  abort: requirement 'fake' not supported!

for all commands in commands.optionalrepo, which includes the identify
and serve commands in particular.

This is for the case when a new entry in .hg/requires will be defined
in a future Mercurial release.
