[libvirt] [PATCH v2] rpc: Allow up to 256K records to be returned per domain from virConnectGetAllDomainStats.

[Richard W.M. Jones]

The number of records that virConnectGetAllDomainStats can return per
domain is currently limited to 4096.  This is quite low -- for
example, a single guest with ~320 disks will hit this limit.  This
increases the limit to make it much larger.  Note that
VIR_NET_MESSAGE_MAX still protects the total message size in the case
where there are many domains and many disks per domain.

I tested this using a guest with 500 disks with no issues.
