Robert Watson ba23fa9bd8 Teach libmemstat(3) how to extract malloc(9) statistics using kvm(3),
so that libmemstat can be used to view full memory statistics from
kernel core dumps and /dev/mem.  This is provided via a new query
function, memstat_kvm_malloc(), which is also automatically invoked
by memstat_kvm_all().  A kvm handle must be passed in.

This will allow malloc(9)-specific code to be removed from vmstat(8).
