Remove scm_unget_{byte,bytes}_unlocked

Browse source 
* libguile/ports.h (scm_unget_bytes_unlocked, scm_unget_byte_unlocked):
  Remove.
* libguile/ports.c (looking_at_bytes): Use scm_unget_bytes instead of
  scm_i_unget_bytes_unlocked
  (scm_unget_bytes): Rename from scm_i_unget_bytes_unlocked.  Remove
  other implementations of this function.
  (scm_unget_byte): Likewise.
  (scm_ungetc_unlocked, scm_peek_char): Use scm_unget_byte.
* libguile/read.c (read_token): Use scm_unget_byte.
