clock

sched/clock: Correct calculation for the case of Tickless mode with a 32-bit timer. In that case, the calculation was returning millisecond accuracy. That is not good when the timer accuracy is < 1 msec.

init

C library: Add ffs(). Add strings.h. Move strcasecmp, strncasecmp, bzero, bcmp, and bcopy to where they belong in strings.h.h, not string.h. bzero, bcmp, and bcopy are legacy functions; the contemporary counterparts should be used instead.

irq

SMP: Fix an error in critical section logic when performing a context switch from an interrupt handler. The g_cpu_irqset bit was not being set for the CPU so other CPUs did not know about the critical section.

mqueue

sigtimedwait: When timer expires, up_unblock_task() is called. This is okay in the single CPU case because interrupts are disable in the timer interrupt handler. But it is insufficient in the SMP case. enter_ and leave_critical_section() must be called in order to manage spinlocks correctly.

Without lowsyslog() *llinfo() is not useful. Eliminate and replace with *info().

Most interrupt handling logic interacts with tasks via standard mechanism such as sem_post, sigqueue, mq_send, etc. This all call enter_critical_section and are assumed to be safe in the SMP case.

wqueue

Signal sent from work_signal() may interrupt the low priority worker thread that is already running. For example, the worker thread that is waiting for a semaphore could be woken up by the signal and break any synchronization assumption as a result. It also does not make any sense to send signal if it is already running and busy. This commit fixes it.
