Committed By:   kamil
Date:           Thu Feb 23 00:50:09 UTC 2017

Modified Files:
        src/sys/kern: sys_ptrace_common.c
        src/tests/kernel: t_ptrace_wait.c

Log Message:
Improve PT_SET_SIGMASK and PT_GET_SIGMASK API in ptrace(2)

Use proper check for LW_SYSTEM, don't depend on PT_GETREGS/PT_SETREGS.
Don't allow to mask SA_CANTMASK signals with PT_SET_SIGMASK (this covers
SIGSTOP and SIGKILL).

Add new ATF tests:
 - setsigmask5
   Verify that sigmask cannot be set to SIGKILL

 - setsigmask6
   Verify that sigmask cannot be set to SIGSTOP
