  build: auto-generate perl subroutines prototypes for automake and aclocal
  
  This will allow us to avoid either using the '&foo' invocation form when
  invoking a subroutine before its definition, or having to maintain the
  list of prototypes by hand (with the risk of having it become incomplete
  or fall out-of-sync when future edits to the automake and aclocal scripts
  are done).
  
  * Makefile.am (automake, aclocal): Automatically generate a list of
  prototypes by looking at the subroutines definitions.
  * bootstrap.sh: Likewise, when generating the temporary automake and
  aclocal scripts used for bootstrapping.
  * automake.in: Add a placeholder that will be tracked by the new recipes
  and substituted with the computed prototypes.  Remove existing prototypes,
  that are now superfluous. Some adjustments required by the new, more
  comprehensive prototypes declarations.
  * aclocal.in: Likewise.
  * maintainer/syntax-checks.mk (sc_diff_automake, sc_diff_aclocal): Adjust.
