declare functions with prototypes.  (Patch thanks to Marius
Vollmer.)

More prototype-related changes from Marius Vollmer:
* gdb_interface.h: Wrapped header file in #ifdef/#endif
* gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
* ports.h (ptobfuns): Added prototypes. This means some casting in
fports.c.
* fports.c: Added casts for initializations, since the functions
are defined to take FILE * as their stream argument, not SCM.
* fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
* genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
to `char *str_data' to conform to prototype.
