NetBSD/arm: disable pax mprotect restrictions for emu

ARM has separate read and execute protection bits so after writing out
JIT code we need to make it executable with mprotect(2), but PAX
wouldn't let us by default. Mark the emu binary so that this
restriction is lifted.

On other machines where this is not an issue set PAXCTL to a no-op.

NetBSD/arm: initial support

This is more or less mechanical merge of existing NetBSD code and
ARM-specific bits from Linux/arm files.

Silently ignore x-special/gnome-copied-files requests.

Modern desktops seem to like to send it a lot so don't spam the user
with repeated messages about it.

Work around a problem on macppc with kernel semaphores.

NetBSD/macppc 7 and later seems to have a bug in kernel based pthread
semaphores. When running emu interactively shell would forever hang
in sem_wait() after the first interactive command.

I added sem_getvalue() after sem_init() as a debugging aid to get the
semaphore id in ktrace output and it magically fixed the problem. For
now just leave it here as a workaround under appropriate ifdef.

Bump Npadlong from 2 to 4 on NetBSD to preserve 16-byte alignment.
pthread interals depend on that as it uses lower bits in some pointers
for flags.

Use SA_SIGINFO to report pc in error messages. Copied from Linux.

On PowerPC tell the JIT compiler it's not Plan9 ABI and it needs to
explicitly clear %r0.
