peek-byte in Scheme
* libguile/ports.c (trampoline_to_c_read, trampoline_to_c_write): Since
C might assume that the indices are within bounds of the bytevector,
verify them more here.
(scm_port_random_access_p, scm_port_read_buffering)
(scm_set_port_read_buffer, scm_port_read, scm_port_write): New helpers
exposed to (ice-9 ports).
(scm_port_read_buffer, scm_port_write_buffer): Don't flush or validate
port mode; we do that in Scheme.
* module/ice-9/ports.scm: Implement enough of port machinery to
implement peek-byte in Scheme. Not yet exported.
