Subject: [PATCH] Remove scm_c_write_unlocked

* libguile/ports.h (scm_c_write_bytes_unlocked): Remove.
* libguile/ports.c (scm_c_write_bytes): Rename from
  scm_c_write_bytes_unlocked, make public, and return void.
  (scm_c_write): Rename from scm_c_write_unlocked.  Remove locked
  variant.
  (scm_lfwrite_unlocked): Call scm_c_write.
* libguile/rw.c (scm_write_string_partial): Call scm_c_write.
