* modules.c (scm_module_reverse_lookup): i, n: int -> scm_bits_t.x

variable is used to store a string length).
(search-path): call scm_done_free, not scm_done_malloc.

* list.c (scm_ilength): return a scm_bits_t, not long.
some other {int,long} -> scm_bits_t changes.

* hashtab.c: various [u]int -> scm_bits_t changes.
scm_ihashx_closure -> scm_ihashx_closure_t (and made a typedef).

there are no nasty surprises if/when the various deeply magic tag
bits move somewhere else.

scm_debug_frame -> scm_debug_frame_t
the old names are deprecated, all in-Guile uses changed.
(scm_debug_eframe_size): int -> scm_bits_t

* debug.c (scm_init_debug): use scm_c_define instead of the
deprecated scm_define.

* continuations.h: type renaming:
scm_contregs -> scm_contregs_t
the old name is deprecated, all in-Guile uses changed.
(scm_contregs_t.num_stack_items): size_t -> scm_bits_t

* continuations.c (scm_make_continuation): change the type of
stack_size form long to scm_bits_t.

* ports.h: type renaming:
scm_port_rw_active -> scm_port_rw_active_t (and made a typedef)
scm_port -> scm_port_t
scm_ptob_descriptor -> scm_ptob_descriptor_t
the old names are deprecated, all in-Guile uses changed.
(scm_port_t.entry): int -> scm_bits_t.
(scm_port_t.line_number): int -> long.
(scm_port_t.putback_buf_size): int -> size_t.

* __scm.h (long_long, ulong_long): deprecated (they pollute the
global namespace and have little value besides that).
(SCM_BITS_LENGTH): new, is the bit size of scm_bits_t (i.e. of an
SCM handle).
(ifdef spaghetti): include sys/types.h and sys/stdtypes.h, if they
exist (for size_t & ptrdiff_t)
(scm_sizet): deprecated.

* Makefile.am (noinst_HEADERS): add num2integral.i.c
