vc04_services contains a debug logging mechanism.  The log is
maintained in a shared memory area between the kernel and the
firmware.  Changing the sizes of the data in this area would
require a firmware change which is distributed independently
from the kernel binary.

One of the items logged is the address of received messages.
This address is a pointer, but the debugging slot used to store
the information is a 32 bit integer.

Luckily, this value is never interpreted by anything other
then debug tools and it is expected that a human debugging
the kernel interpret it.

This change adds a cast to long before the original cast
to int to silence the warning.

The vchiq_copy_from_user function is not portable
and is consider "bad practice."  Replace this function
with a callback based mechanism that is passed downward
on the stack.  When it is actually time to copy the data,
the callback is called to copy the data into the message.

This callback is provided internally for userland calls
through ioctls on the device.

NOTE: Internal clients will need to be modified to work
with the new internal API.

Test Run:
vchiq_test -p 1
vchiq_test -f 10

Both tests pass.

Internal API Changes:

Change vchi_msg_queue to:
int32_t
vchi_msg_queue(VCHI_SERVICE_HANDLE_T handle,
	       ssize_t (*copy_callback)(void *context, void *dest,
				        size_t offset, size_t maxsize),
	       void *context,
	       uint32_t data_size );

Remove:
vchi_msg_queuev_ex
vchi_msg_queuev

These functions were not implemented anyway so no need to fix them. It's
easier to just remove them.
