* 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.
