it is alive!!!!! + concision + fix to compile-ghil

* module/ice-9/boot-9.scm: Remove lots of debugging prints. Remove some
  already-deprecated attempts to load modules from shared libraries.

* module/ice-9/psyntax.scm: If we have to create a variable for a
  syntactic binding, initialize its contents to a gensym. I'd like
  something more meaningful, but at least this way we can tell different
  macros apart. Only warn about missing modules if modules are booted.
  Chi the value part of a (set! (@ ...) ) expression -- whoops!

* module/ice-9/psyntax-pp.scm: Regenerated.

* module/language/glil.scm (parse-glil): Fix an unquoting error.

* module/language/scheme/compile-ghil.scm: No need to import syncase, we
  gots it. Rework compiler to expand only once, with syncase, instead of
  incrementally. Fix define-scheme-transformer to work with syncase, by
  not referencing bare keywords. It works!
