rename guile-tools' to guild'

* configure.ac: Look for ln -s.  Write out `guild' instead of
  `guile-tools'.

* meta/Makefile.am (install-data-hook): Link the installed `guild' to
  the backward-compatible `guile-tools' name.
  (bin_SCRIPTS, EXTRA_DIST): Fix up for guild change.

* meta/guild.in: Moved here from `guile-tools.in'.

* doc/ref/Makefile.am (autoconf-macros.texi):
* doc/ref/api-evaluation.texi (Compilation):
* doc/ref/autoconf.texi (Autofrisk, Using Autofrisk):
* doc/ref/mod-getopt-long.texi (getopt-long Reference):
* doc/ref/tools.texi (Miscellaneous Tools, Executable Modules): Minimal
  doc update.

* .gitignore:
* am/guilec (.scm.go):
* libguile/Makefile.am (snarf2checkedtexi):
* module/Makefile.am (ice-9/psyntax-pp.go): Update makefiles, etc.

* module/scripts/README:
* module/scripts/lint.scm:
* module/scripts/list.scm: Update commentaries.
