I'd prefer the name scm_c_define_hook or something for consistency with
snarf macros.  The form could be either

  hook = scm_c_define_hook (name, nargs);

or

  scm_c_define_hook (&hook, name, nargs);

I'd also like if all procedures that create and define something at the
same time had the same prefix like `scm_c_define_'.  For example,
`scm_make_gsubr' could be `scm_c_define_procedure'.  (And I guess we'll
probably need an Emacs command guile-c-complete-symbol :)

I also have a question about hooks.  Guile has two kinds of hooks:
C hooks and Scheme hooks.  There are two different functions
scm_c_hook_run and scm_c_run_hook, for example.  This is very
confusing.  Is there any good reason to do so, or is this going to be
rewritten?  (If there is a reason related to GC, I think the GC version
should be named differently...)
