Hi folks...

I have changed NetBSD to use a libc-provided signal trampoline.  For
the reasoning behind this, see tech-kern.

I've made changes to all of the platforms except the new SH5 port (I
have discussed this with Steve Woodford, and he'll take care of SH5
soon).  There were a couple that I wasn't able to test directly, but
everything is working fine on alpha, arm, i386, sparc64, and vax.

Just in case, it might be a good idea to make a backup copy of your
libc.so.12.85 before updating your libc next time.  And make absolutely
sure you're running a new kernel before installing a new libc.

If you encounter any problems, please send a bug report with send-pr,
and I will address it as quickly as possible.

Enjoy!

Log Message:
Enable the libc-provided signal trampoline.  The old __sigaction14
entry point has been replaced by the new __sigaction14() which is a
wrapper around the __sigaction_sigtramp system call (which is itself
not directly exposed outside of libc).

No shared library version change is necessary; no new symbols
are exposed outside of libc.
