When MSI is off, each interrupt needs to be bounced through the io
thread when it's set/cleared, so vhost-net causes more context switches and
higher CPU utilization than userspace virtio which handles networking in
the same thread.
We'll need to fix this by adding level irq support in kvm irqfd,
for now disable vhost-net in these configurations.
Added a vhostforce flag to force vhost-net back on.

file.index is unsigned, hence 'while (--file.index >= 0)'
will loop > forever. Change to while (file.index-- > 0).

This header is not present on my system and causes a build
failure, but is also not used in these files, so remove it.

Fix build failure introduced by 0bfcd599e3f5c5679cc7d0165a0a1822e2f60de2
The format statement expects unsigned long on x86_64, but receives
unsigned long long, so gcc exits with an error.

vhost in current kernels doesn't support mergeable buffers.
Disable this feature if vhost is enabled, until such
support is implemented.

This adds vhost net device support in qemu. Will be tied to tap device
and virtio by following patches. Raw backend is currently missing,
will be worked on/submitted separately.
