Andy Wingo e809758a7e clean up macros.[ch]
There are some incompatible changes here, but only to interfaces that
were introduced earlier in 1.9, or interfaces which have been broken
since early in 1.9.

* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump, as the macro
  changes affect the interface that is called by psyntax-generated macro
  definitions.

* libguile/inline.h (scm_words): New function, allocates a variable
  number of contiguous scm_t_bits locations, with a given value in the
  0th word, and 0 in the rest of the words.

* libguile/macros.h: Rework interface to correspond more closely, and
  minimally, to the needs of memoize.c and psyntax.
  (SCM_ASSYNT, SCM_MACRO_TYPE_BITS, SCM_MACRO_TYPE_MASK)
  (SCM_F_MACRO_EXTENDED, SCM_MACROP, SCM_MACRO_TYPE)
  (SCM_MACRO_IS_EXTENDED, SCM_BUILTIN_MACRO_P, SCM_SYNCASE_MACRO_P)
  (SCM_MACRO_CODE, scm_tc16_macro): Remove CPP macros related to the
  representation of Scheme macros.
  (scm_i_make_primitive_macro): Renamed from scm_i_makbimacro.
  (scm_i_macro_primitive): New accessor so that memoize.c can get to the
  primitive syntax transformer.
  (scm_make_syncase_macro, scm_make_extended_syncase_macro)
  (scm_syncase_macro_type, scm_syncase_macro_binding): Removed these
  functions, replaced by make-syntax-transformer and its accessors.
  (scm_macro_binding): New accessor, the same as what
  scm_syncase_macro_binding was.

* libguile/macros.c: All representation details of syntax transformers
  are private to this file now.
  (macro_print): Print macros as #<syntax-transformer ...>, or
  #<primitive-syntax-transformer ...> if psyntax has not attached a
  transformer of its own.
  (scm_i_make_primitive_macro): Represent macros as 5-word smobs.
  (scm_make_syntax_transformer): New constructor for syntax transformers
  (macros), exported to scheme. Takes a name, and looks it up in the
  current module to determine the previous primitive transformer, if
  any.
  (scm_macro_type): Instead of returning 'builtin-macro!, etc, return
  the type as set by psyntax, or #f if it's a primitive.
  (scm_macro_name): Return the stored macro name.
  (scm_macro_transformer): Return the psyntax-set syntax transformer.
  Hacky, but should help introspection somewhat.

* libguile/memoize.c (memoize_env_ref_transformer): Use the new
  scm_i_macro_primitive, and adapt to other macro API changes.

* module/ice-9/psyntax.scm (put-global-definition-hook)
  (get-global-definition-hook, chi-install-global): Call (and generate
  calls to) the new macro constructors and accessors.

* module/ice-9/psyntax-pp.scm: Doubly regenerated.

* module/ice-9/debugging/traps.scm (trap-here): Comment out this
  definition and export, while it's not working.
