[ANNOUNCE] kvm-84 release

[Avi Kivity <avi@redhat.com>]

A long list of changes due to an unusually late release.  As is becoming 
usual, many of the changes come from upstream qemu; the kvm specific 
changes are mostly bugfixes, but also include infrastructure intended 
for message-signalled interrupts (MSI).

kvm-84 is slower when rendering fonts on Windows than kvm-83; we are 
still investigating why.
