* Makefile.am: Fix ETAGS_ARGS to recognize GUILE_PROC,

GUILE_PROC1.  Build guile-procedures.txt, and add that file to
pkgdata_DATA.

* load.c: Added `pkgdata-dir', `site-dir', `library-dir'
primitives.

* guile-doc-snarf.awk: Drop trailing space when no arguments:
e.g., "(foo )" is now "(foo)".

* *.c: moved all the documentation for primitives from
guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
This leaves about half of the primitives undocumented.  Also, all
the markup is currently still texinfo.  I don't have a problem
with texinfo per se, but the markup is not very descriptive or
accurate.
