Move the source code (other than glob) into the "src" subdirectory.
Update all scripting and recommendations to support this change.
* *.c, *.h, w32/*: Move to src/
* configure.ac, Makefile.am, maintMakefile: Locate new source files.
* Basic.mk.template, mk/*: Update for new source file locations.
* NEWS, README.DOS.template: Update for new locations.
* build.template, build_w32.bat, builddos.bat: Ditto.
* po/POTFILES.in: Ditto
* tests/run_make_tests.pl, tests/scripts/features/load*: Ditto.
* make.1: Move to doc.
* mk/VMS.mk: Add support for building on VMS (hopefully).
* makefile.vms, prepare_w32.bat: Remove.
* SCOPTIONS: Update to define HAVE_CONFIG_H
* guile.c (guile_gmake_setup) [HAVE_GUILE]: Define a stub function
when Guile support is not enabled.
* main.c (main) [HAVE_GUILE]: Always invoke guile_gmake_setup().
* Makefile.am: Make guile.c standard, not optional.
* build.template: Add the Guile compiler and linker flags.
* Update maintainers build process; remove GNUmakefile. Require builders to
run automake && autoreconf by hand.
* Use AC_SUBST_FILE to get the maintMakefile included, rather than GNU
make's include directive, which conflicts with automake 1.4's include
directive.
* Check for a libc version of GNU glob and, if found, don't use the local
glob headers.
* Fix a bug in OpenVMS archive handling.
* Fix a bug in VMS siglist processing.
