checks userland-parsing vs kernel parsing, we are hoping to spot another
bug..

For now, this also still uses the existing realpath implmentation
and emits a syslog if we see differening results. Once we have run
with that for a little while we will remove the old code

This commit moves the BER API into /usr/lib/libutil. All current consumers
already link libutil. ldapd and snmpd regress passes, and release builds.

free() freezero() is actually called.

allocate pages, don't call abort() because of corefile data leakage
concerns, but simply _exit().  The reasoning is _rs_init() will only
fail if someone finds a way to apply specific pressure against this
failure point, for the purpose of leaking information into a core which
they can read.  We don't need a corefile in this instance to debug that.
So take this "lever" away from whoever in the future wants to do that.

libs have it, it is a function that is considered harmful, so:
Delete malloc_usable_size(). It is a function that blurs the line
between malloc managed memory and application managed memory and
exposes some of the internal workings of malloc.  If an application
relies on that, it is likely to break using another implementation
of malloc.  If you want usable size x, just allocate x bytes. ok
