* backtrace.c (scm_set_print_params_x): Renamed from
set_print_params_x.

* guile-doc-snarf.in: Use guile-snarf.awk, not
guile-doc-snarf.awk.  Pass the basename of $filename

* load.h: Added prototypes for scm_sys_library_dir,
scm_sys_site_dir.

* load.c (scm_sys_library_dir, scm_sys_site_dir):  Added these
functions, and took out the old scm_library_dir, scm_site_dir,
scm_pkgdata_dir.  Now the primitives are %package-data-dir
(already existed), %library-dir, and %site-dir.

* debug.c: Use SCM_MISC_ERROR when possible instead of using
s_scm_* in a scm_misc_error() call.

* Makefile.am: Use guile-snarf.awk, not guile-doc-snarf.awk.  Make
using guile-doc-snarf send stdout to $@ to create the .x file like
guile-snarf does.
