kernel/tasks: fix minor bug in check_scheduling()
...
If the prio_bitmap is 0, msb() will return 64 which will be greater
than the current priority in any case. While this was a bug, it only
triggered a useless rescheduling and didn't affect correctness.

x86/irq: check_workqueues() after custom IRQ handler has run + refactoring
...
When HermitCore is compiled with periodic ticks, the timer handler will
increase the local tick count, so check_workqueues() would only recognize
the increased ticks on the next call, therefore call it after the IRQ
handler.

hermit/kernel: implement signal handling for communication between tasks
...
When a signal is sent, the operating system interrupts the target task's
normal flow of execution to deliver the signal. Execution can be
interrupted during any non-atomic instruction. If the process has
previously registered a signal handler, that routine is executed when the
task's execution would continue.
