Attempt to use AT_PS_STRINGS to get the ps_strings pointer.

This saves a system call and avoids one of the (relatively rare) cases
of the kernel exporting pointers via sysctl.

As a temporary measure, keep the sysctl support to allow limited
compatability with old kernels.

Fail gracefully if ps_strings can't be found (should never happen).

Add setproctitle_fast(3) for frequent callers.

Some applications, notably PostgreSQL, want to call setproctitle()
very often. It's slow. Provide an alternative cheap way of updating
process titles without making any syscalls, instead requiring other
processes (top, ps etc) to do a bit more work to retrieve the data.
This uses a pre-existing code path inherited from ancient BSD, which
always did it that way.
