Add new interface to add ability to get/set signal mask of a tracee.
It has been inspired by Linux PTRACE_GETSIGMASK and PTRACE_SETSIGMASK, but
adapted for NetBSD API.
This interface is used for checkpointing software to set/restore context
of a process including signal mask like criu or just to track this property
in reverse-execution software like Record and Replay Framework (rr).
Add new ATF tests for this interface
====================================
getsigmask1:
Verify that plain PT_SET_SIGMASK can be called
getsigmask2:
Verify that PT_SET_SIGMASK reports correct mask from tracee
setsigmask1:
Verify that plain PT_SET_SIGMASK can be called with empty mask
setsigmask2:
Verify that sigmask is preserved between PT_GET_SIGMASK and
PT_SET_SIGMASK
setsigmask3:
Verify that sigmask is preserved between PT_GET_SIGMASK, process
resumed and PT_SET_SIGMASK
setsigmask4:
Verify that new sigmask is visible in tracee
Kernel ABI bump delayed as there are more interfaces to come in ptrace(2).

$NetBSD: README,v 1.4 2012/05/18 15:36:21 jruoho Exp $ When adding new tests, please try to follow the following conventions. 1. For library routines, including system calls, the directory structure of the tests should follow the directory structure of the real source tree. For instance, interfaces available via the C library should follow: src/lib/libc/gen -> src/tests/lib/libc/gen src/lib/libc/sys -> src/tests/lib/libc/sys ... 2. Equivalently, all tests for userland utilities should try to follow their location in the source tree. If this can not be satisfied, the tests for a utility should be located under the directory to which the utility is installed. Thus, a test for env(1) should go to src/tests/usr.bin/env. Likewise, a test for tcpdump(8) should be in src/tests/usr.sbin/tcpdump, even though the source code for the program is located under src/external. 3. Otherwise use your own discretion.
