some other {int,long} -> scm_bits_t changes.

(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.
