Remove PT_GET_SIGMASK / PT_SET_SIGMASK
These operations cloned Linux's specific PTRACE_GETSIGMASK /
PTRACE_SETSIGMASK.
This feature was useful in applications like rr/criu/reptyr-like, where
the ptrace(2) interface is abused for the purpose of constructing an
arbitrary
process. It's not reliable and not portable. For the NetBSD case it will =
be
better to invent something dedicated for serializing and deserializing a
process with threads.
