guile/libguile/async.h
Andy Wingo a0656ad4cf New interfaces to help wait on fd/cond
* libguile/async.h:
* libguile/async.c (struct scm_thread_wake_data): Include the cond to
  signal.  Be a union and include a tag.
  (scm_i_prepare_to_wait): Rename from scm_i_setup_sleep and take wake
  data directly.  Also call scm_i_wait_finished as appropriate.
  (scm_i_wait_finished): Rename from scm_i_reset_sleep.
  (scm_i_prepare_to_wait_on_fd, scm_c_prepare_to_wait_on_fd):
  (scm_i_prepare_to_wait_on_cond, scm_c_prepare_to_wait_on_cond): New
  functions.
  (scm_c_wait_finished): New function.
  (scm_system_async_mark_for_thread): Adapt to wake data change.
* libguile/threads.c (block_self, scm_std_select): Adapt to async
  interface changes.
* doc/ref/api-scheduling.texi (Asyncs): Doc new public interfaces.
