simplify macro representation in the wake of module hygiene changes

Browse source 
* module/ice-9/psyntax.scm (chi-install-global, chi-macro)
  (eval-local-transformer): Now that we handle module hygiene through
  syntax objects, there is no more need to record the current module
  when installing syntax transformers.

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

* libguile/_scm.h: Bump objcode version for macro representation change.

* libguile/macros.c (scm_macro_transformer): Adapt to change in macro
  representation.
