Subject: Merge from Lionel Elie Mamane's private branch:

 - Makefile: Option (environment variable NO_RECOMPILE_LIB) to not
   recompile the whole standard library just because the coq binaries
   got rebuilt.

 - Infrastructure to change the object pretty-printers at runtime.

 - Use that infrastructure to make coqtop-protocol with Pcoq trees and
   Pcoq-protocol with pretty-printed terms possible in coq-interface.

 - Make "Back(track)" into closed sections, modules and module types
   "Just Work™".

 - Modernise/generalise Pcoq protocol a bit, make some of its warts
   optional.

 - Implement "Show." in Pcoq mode.

 - Add Rpow_def.vo to REALSBASEVO so that its dependencies are
   computed (and used).

 - "make revision" now handles GNU Arch / tla in addition to svn.
