When HAVE_VALGRIND is set, vbits of the CPU mapping are stored when
pvr_bo_cpu_unmap() is called. They can be reloaded by calling
pvr_bo_cpu_map_unchanged() instead of pvr_bo_cpu_map(). The vbits are
not loaded by default on every map, since they could easily have been
changed by the device between the unmap/map calls. Only use
pvr_bo_cpu_map_unchanged() when you can safely assume that nothing has
changed in the underlying memory.
When HAVE_VALGRIND is not set, pvr_bo_cpu_map_unchanged() just inlines
to pvr_bo_cpu_map().

This is the legacy way of doing synchronisation and is no longer necessary now
that the DMA_BUF_IOCTL_EXPORT_SYNC_FILE / DMA_BUF_IOCTL_IMPORT_SYNC_FILE ioctls
exist, which the wsi code is already making use of.

This type is useful beyond the scope of winsys.
It can now be used without being lumbered with a dependency on
pvr_winsys.h. Since pvr_winsys.h is used by pvr_private.h, this can be
a common cause for circular dependencies during development.

Since the packing functions generated by csbgen use a void pointer
for the buffer in which to pack, it's possible to easily write out
of bounds. This commits attempts to reduce the chances by
having the pack macro check that the pointer passed points to an
element sized equally to the state word being packed. Catching
these errors earlier.
As can be seen in this commit, there already was a case of this:
"pds_ctrl". The word size is meant to be 64 bits but the pointer
was pointing to a 32 bit field.
Although it's fine for the word size to be smaller than the
storage pointed to by the pointer, this is not allowed just to
be extra careful.
