Fix widespread leak in the sendsig_siginfo() functions. sigframe_siginfo
has padding, so zero it out properly. While here I'm also zeroing out some
other things in several ports, for safety. Same problem in netbsd32, so
fix that too.

I can't compile-test on each architecture, but there should be no
breakage (tm).

Overall this fixes at least 14 info leaks. Prompted by the discovery by
KLEAK of a leak in amd64's sendsig_siginfo.

Beginnings of RISCV kernel support.  Note that the pmap support is not yet
committed and probably won't be for awhile.  This is mostly preliminary
waiting for the supervisor specification to come out.  Lots of missing pieces
but it mostly builds.
