* thread.h: Add background thread type and thread_add_background
macro and accompanying funcname_... function.
export thread_should_yield, background threads can use it.
Lower thread yield time to 10ms, 100ms is noticeable lag and
a thread would only be /starting/ to finish sometime afterward.
* thread.c: (general) Add background thread type and schedule
nearly all thread types through the ready list for fairness.
(timeval_adjust) static qualifier missing
(vty_out_cpu_thread_history) add support for printout of
background threads
(show_thread_cpu) ditto.
(thread_master_debug) add debug of background list
(thread_master_create) fixup long line
(thread_add_unuse) add asserts for required state.
(thread_master_free) free background thread list
(funcname_thread_add_timer_timeval) make generic, able to
support arbitrary timer-like thread types.
(funcname_thread_add_timer) pass thread type to .._add_timer_timeval
(funcname_thread_add_timer_msec) ditto
(funcname_thread_add_background) Add a background thread, with an
optional millisecond delay factor, using .._add_timer_timeval.
(thread_cancel) Add background thread type.
Move the thread_list_delete common to all cases to bottom of
function, after the switch statement..
(thread_cancel_event) indent
(thread_timer_wait) Static qualifier, and make it able to cope
with arbitrary timer-like thread lists, so its of use to
background threads too.
(thread_process_fd) static qualifier. Again, make it take a list
reference rather than thread_master. Fix indentation.
(thread_timer_process) Check for ready timer-like threads in the
given list and move them on to the ready list - code originally
embedded in thread_fetch.
(thread_fetch) Schedule all threads, other than events, through
the ready list, to ensure fairness. Timer readying code moved to
thread_timer_process so it can be reused for background threads.
Remove the unneeded quagga_sigevent_process, as pointed out by
John Lin <john.ch.lin@gmail.com>.
(thread_should_yield) make this available.
