maint: use more perl subroutines prototypes in the automake script
* automake.in: Throughout this file. Note that these new prototypes
are not much useful, since many subroutine calls still use the old
'&foo' form; but we'll take care of that in later patches.
* lib/Automake/Language.pm (target_hook): Call the '_target_hook'
of the given language in a more modern form, avoiding '&'.

refactor: rip module Automake::Language out of automake script
This is just a preparatory patch in view of future changes.
* lib/Automake/Language.pm: New module, ripped out from ...
* automake.in: ... here. Related adjustments.
* Makefile.am (dist_perllib_DATA): List the new module.
