Improvements in git2chg.awk and grecs setup sequence.

* build-aux/git2chg.awk: New configuration variables:
since=YYYY-MM-DD, to cut off entries earlier than the
given date, and append=FILE, to append FILE to the
generated ChangeLog.
* am/grecs.m4 (GRECS_HOST_PROJECT_INCLUDES): New substitution
variable.
* src/Make.am (INCLUDES): Expand GRECS_HOST_PROJECT_INCLUDES.
* tests/Makefile.am: Likewise.
