kvm tools: Fix PCI masking on probes

This patch adds a missing check of mask during probing of PCI BARs.

The missing check manifested in wrong address values for the BARs after the
initial probe.

kvm tools, vesa: Use guest-mapped memory for framebuffer

This patch converts hw/vesa.c to use guest-mapped memory for framebuffer and
drops the slow MMIO emulation. This speeds up framebuffer accesses
considerably. Please note that this can be optimized even more with the
KVM_GET_DIRTY_LOG ioctl() as explained by Alexander Graf.

kvm tools: Add MMIO coalescing support

Coalescing MMIO allows us to avoid an exit every time we have a
MMIO write, instead - MMIO writes are coalesced in a ring which
can be flushed once an exit for a different reason is needed.
A MMIO exit is also trigged once the ring is full.

Coalesce all MMIO regions registered in the MMIO mapper.
Add a coalescing handler under kvm_cpu.
