Expose the amount of resident and wired memory from the guest's vmspace.

This is different than the amount shown for the process e.g. by
/usr/bin/top - that is the mappings faulted in by the mmap'd region
of guest memory.

The values can be fetched with bhyvectl

 # bhyvectl --get-stats --vm=myvm
 ...
 Resident memory                         	413749248
 Wired memory                            	0
 ...

vmm_stat.[ch] -
 Modify the counter code in bhyve to allow direct setting of a counter
as opposed to incrementing, and providing a callback to fetch a
counter's value.

Add another RSS method to query the indirection table entries.

There's 128 indirection table entries which correspond to the
low 7 bits of the 32 bit RSS hash.  Each value will correspond
to an RSS bucket.  (Then each RSS bucket currently will map
to a CPU.)

This is a more explicit way of figuring out which RSS bucket
is in each RSS indirection slot.  It can be inferred by the other
methods but I'd rather drivers use something more simplified and
explicit.
Retire IP_RSSCPUID ; the right thing to do is query the RSS bucket;
map the bucket to an RSS queue, then map the queue to a CPU ID.
This way the bucket->queue and queue->CPU mapping can change
over time.

Introduce IP_RSSBUCKETID - which instead looks up the RSS bucket.
User applications can then map the RSS bucket to a CPU.
Improve r264388 removing namespace pollution previously introduced in
<sys/time.h>. INT64_MAX actually requires __INT64_C() hack to get the
type right on exotic architectures (e.g. on ones with 63-bit ints or long
0x7fffffffffffffff is unsigned int or long). The hardcoded LL suffix is
good enough to avoid these problems for SBT_MAX (it makes the type always
signed long long, without overflow since long long has at least 64 bits).
Many thanks to Bruce Evans for the time spent me to explain this.

Add READ BUFFER and improve WRITE BUFFER SCSI commands support.

This gives some use to 512KB per-LUN buffers, allocated for Copan-specific
processor code and not used.  It allows, for example, to test transport
performance and/or correctness without accessing the media, as supported
by Linux version of sg3_utils.
