        src/lib/libc/sys: ptrace.2
        src/sys/kern: kern_sig.c sys_ptrace_common.c
        src/sys/sys: ptrace.h signalvar.h

Log Message:
Introduce new ptrace(2) operations: PT_SET_SIGPASS and PT_GET_SIGPASS

They deliver the logic of bypassing selected signals directly to the
debuggee, without informing the debugger.

This can be used to implement the QPassSignals GDB/LLDB protocol.

This call can be useful to avoid signal races in ATF ptrace tests.
