Few devices have their specialized 'config_write' methods which simply
call 'pci_default_write_config' followed by a 'msix_write_config' or
'msi_write_config' calls, using exact same arguments.
This is unnecessary as 'pci_default_write_config' already invokes
'msi_write_config' and 'msix_write_config'.
Also, since 'pci_default_write_config' is the default 'config_write'
handler, we can simply avoid the registration of these specialized
versions.

Mac OS X calibrates a number of frequencies on bootup based on reading
tb values on bootup and comparing them to via cuda timer values.
The only variable we can really steer well (thanks to KVM) is the cuda
frequency. So let's use that one to fake Mac OS X into believing the
bus frequency is tbfreq * 4. That way Mac OS X will automatically
calculate the correct timebase frequency.
With this patch and the patch set I posted earlier I can successfully
run Mac OS X 10.2, 10.3 and 10.4 guests with -M mac99 on TCG and KVM.

When new MSI-X vectors are enabled we need to disable MSI-X and
re-enable it with the correct number of vectors. That means we need
to reprogram the eventfd triggers for each vector. Prior to f4d45d47
vector->use tracked whether a vector was masked or unmasked and we
could always pick the KVM path when available for unmasked vectors.
Now vfio doesn't track mask state itself and vector->use and virq
remains configured even for masked vectors. Therefore we need to ask
the MSI-X code whether a vector is masked in order to select the
correct signaling path. As noted in the comment, MSI relies on
hardware to handle masking.

Slow BAR access path is used when VFIO fails to mmap() BAR.
Since this is just a transport between the guest and a device, there is
no need to do endianness swapping.
This changes BARs to use native endianness. Since non-ROM BARs were
doing byte swapping, we need to remove it so does the patch.
As the result, this eliminates cancelling byte swaps and there is
no change in behavior for non-ROM BARs.
ROM BARs were declared little endian too but byte swapping was not
implemented for them so they never actually worked on big endian systems
as there was no cancelling byte swap. This fixes endiannes for ROM BARs
by declaring them native endian and only fixing access sizes as it is
done for non-ROM BARs.
