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.

x86/apic: same calibration for single and multi kernel

Sample CPU timestamp counter for APIC calibration in both cases. This
has proven to be more reliable than waiting for and counting timer
interrupts.

gdb-scripts: backtrace and context switching for tasks
...
These new commands allow to show backtraces of any HermitCore task as
well as completely switching the current context. This way, you can
inspect each task as if it were running, which hasn't been possible
until now, because neither GDB nor Qemu have knowledge about the task
structure of HermitCore.
