This commit allows most of Gash to be built with Autotools. It also
removes some of the Gash build scripts.
* configure.ac: Add checks for compress, gzip, bzip2, and xz;
configure gash/config.scm.
* Makefile.am: Add Gash modules and the 'gash' script.
* scripts/gash.in: Rename 'guile_site_dir' to 'MODDIR' and
'guile_site_ccache_dir' to 'GODIR'.
* configure: Delete file.
* makefile: Delete file.
* build-aux/build-guile.sh: Delete file.
* build-aux/pre-inst-env.in: Delete file.
* build-aux/trace.sh: Delete file.
* .gitignore: Add configure; remove exceptions for the deleted
build-aux files.
* build-aux/git-version-gen: New file.
* .gitignore: Do not ignore it.
* configure.ac: Use it to generate the version string.
* guix.scm: Ditto.
* Makefile.am: Make .tarball-version.
* configure.ac: Do not treat scripts/geesh as an AC_CONFIG_FILE.
* Makefile.am: Do the substitutions here (at make-time).
* scripts/geesh.in: Update %load-path and %load-compiled-path
explicitly before loading anything.
tests/spec/oil.scm: New file.
tests/spec/check-spec: New file.
tests/spec/Makefile.am: New file.
configure.ac: Add the new Makefile.
Makefile.am (check-spec): New rule for running Oil shell
specification tests.
(clean-local): New rule that tells Automake how to clean up the
specification tests.
.gitignore: Add tests/spec/oil and tests/spec/oil-link.
