Since commit ab06ec43577177a442e8 we test the vmxnet3 device in the
pxe-tester, too (when running "make check SPEED=slow"). This now
revealed that the code is not working there if the host is a big
endian machine (for example ppc64 or s390x) - "make check SPEED=slow"
is now failing on such hosts.
The vmxnet3 code lacks endianness conversions in a couple of places.
Interestingly, the bitfields in the structs in vmxnet3.h already tried to
take care of the *bit* endianness of the C compilers - but the code missed
to change the *byte* endianness when reading or writing the corresponding
structs. So the bitfields are now wrapped into unions which allow to change
the byte endianness during runtime with the non-bitfield member of the union.
With these changes, "make check SPEED=slow" now properly works on big endian
hosts, too.

When a PCI device lives behind an IOMMU, it should use 'pci_dma_*' family of
functions when any transfer from/to guest memory is required while
'cpu_physical_memory_*' family of functions completely bypass any MMU/IOMMU in
the system.
vmxnet3 in some places was using 'cpu_physical_memory_*' family of functions
which works fine with the default QEMU setup where IOMMU is not enabled but
fails miserably when IOMMU is enabled. This commit converts all such instances
in favor of 'pci_dma_*'

Replace the uint8 softfloat-specific typedef with uint8_t.
This change was made with
find include hw fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\buint8\b/uint8_t/g'
together with manual removal of the typedef definition and
manual fixing of more erroneous uses found via test compilation.
It turns out that the only code using this type is an accidental
use where uint8_t was intended anyway...
