freebsd32: add stubs for ofreebsd32_(send|recv)msg

The upcoming change to generate freebsd32 generated files from
sys/kern/syscalls.master doesn't have a way to handle disabling
this one without disabling the non-COMPAT counterpart so just add
a stub for now.

freebsd32_abort2 is in it's own file with a 2-clause BSD license
based on a discussion with Wojciech many years ago.

freebsd32: add feed foward clock syscalls

These are required when supporting i386 because time_t is 32-bit which
reduces struct bintime to 12-bytes when combined with the fact that 64-bit
integers only requiring 32-bit alignment on i386. Reusing the default
ABI version resulted in 4-byte overreads or overwrites to userspace.

freebsd32: don't implement kldsym

Previously we fell back to sys_kldsym, but because we'd always
mismatch on the version field we'd return EINVAL. A freebsd32
implementation is impossible with the current ABI as there simply
isn't space to store a kernel virtual address in a uint32_t.

pipe requires no special handling.

ofreebsd32_sigpending did differ from osigpending in that it acted

oversight in 3fbdb3c21524d9d95278ada1d61b4d1e6bee654b.

ogetpagesize could theoretically have ABI-dependent results, but in
practice does not. If it does it would be easy handle in the central
implementation and be the least of the problems in changing the value of
PAGE_SIZE.
