commit c5db278746daedcc6566822992f3f33ce3801470

    sockets: Refactor event_callback()
    
    This refactors event_callback() to separate updating socket event
    state from processing the select list (to apply socket event change)
    
    Refactoring changes:
    
    1) select_list_cb processing has been moved to a new local function called
    select_check_waiters()
    2) goto no_select_wakeup has been removed and now we use a flag
    to track whether to call select_check_waiters()
    3) There is a small functional change for !LWIP_TCPIP_CORE_LOCKING.
    We call SYS_ARCH_UNPROTECT after saving events but before calling
    select_check_waiters() (which now calls PROTECT before starting the loop).
    Before the code held the PROTECT across saving the events and the first
    loop iteration, but this didn't protect against anything because each loop
    iteration we do an UNPROTECT/PROTECT
    4) Better documentation for both LWIP_TCPIP_CORE_LOCKING and
    !LWIP_TCPIP_CORE_LOCKING
