Robert Watson 1d90b80f28 The uma_zone data structure defines the size of its uz_cpu[] array as 1, 
but then sizes the containing data structure at run-time to make room
for per-cpu cache data.  Modify libmemstat to separately allocate a
buffer to hold per-cpu cache data, sized based on the run-time mp_maxid
variable when using libkvm to access UMA data.  This avoids reading
invalid cache data from beyond the end of the uma_zone data structure
on the stack, which can result in invalid statistics and/or reads from
invalid kernel addresses.

Robert Watson 59e012a852 When reporting an error reading from UMA per-cpu cache pointers using KVM, 
return a KVM error rather than an out of memory error, so that the caller
reports the KVM error state.  This replaces a misleading error message
with a more accurate although equally confusing one.

Robert Watson 3f374960e6 Read all_cpus variable out of kmem, and validate CPUs against the all_cpus
