This patch introduces the routines ptrace_get_gpregs() and ptrace_set_gpregs()
that wrap the ptrace interface to get and set CPU registers respectively.
The motivation is to make the CRIU code be compatible with architectures that
don't support the PTRACE_GETREGS and PTRACE_SETREGS ptrace calls ---
the requests PTRACE_GETREGSET and PTRACE_SETREGSET are implemented instead.
