build: improved mechanism for copying .shipped files.
* Makefile (SHIPPED): New variable, holds names of files that
get copied to a .shipped suffix and commited to the repo.
(ABBREV3SH): New macro, version of ABBREV3 that doesn't assume
it is expanding an entire recipe line, and thus can be
embedded into shell commands.
(%.shipped): Rule removed.
(shipped): New rule that prints what it is copying.
Non-maintainer version of rule errors out.
