When setting a control the control's new value is compared to the current
value twice: once by new_to_cur(), once by cluster_changed(). Not a big
deal when dealing with simple values, but it can be a problem when dealing
with compound types or arrays. So fix this: cluster_changed() sets the
has_changed flag, which is used by new_to_cur() instead of having to do
another compare.

In order to implement array support and (for the future) configuration stores
we need to have more generic copy routines that all operate on the v4l2_ctrl_ptr
union. So instead of e.g. using ctrl->cur.string it uses ptr.p_char. This makes
e.g. cur_to_user generic so it can be used to copy any v4l2_ctrl_ptr value to

Since compound controls can have non-standard types we need to be able to do
type-specific checks etc. In order to make that easy type operations are added.
There are four operations:
- equal: check if two values are equal
- init: initialize a value
- log: log the value
- validate: validate a new value
The v4l2_ctrl struct adds p_new and p_cur unions at the end of the struct.
This union provides a standard way of accessing control types through a pointer,
which greatly simplifies internal control processing.

If a struct contains 64-bit fields, it is aligned on 64-bit boundaries
within containing structs in 64-bit compilations. This is the case with
struct v4l2_window, which contains pointers and is embedded into struct
v4l2_format, and that one is embedded into struct v4l2_create_buffers.
Unlike some other structs, used as a part of the kernel ABI as ioctl()
arguments, that are packed, these structs aren't packed. This isn't a
problem per se, but the ioctl-compat code for VIDIOC_CREATE_BUFS contains
a bug, that triggers in such 64-bit builds. That code wrongly assumes,
that in struct v4l2_create_buffers, struct v4l2_format immediately follows
the __u32 memory field, which in fact isn't the case. This bug wasn't
visible until now, because until recently hardly any applications used
this ioctl() and mostly embedded 32-bit only drivers implemented it. This
is changing now with addition of this ioctl() to some USB drivers, e.g.
UVC. This patch fixes the bug by copying parts of struct
v4l2_create_buffers separately.

The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.
The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.
The pwc amd sdr-msi3101 drivers both had this construction:
if (mutex_lock_interruptible(&s->v4l2_lock))
return -ERESTARTSYS;
This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

Added a vb2_fileio_is_active inline function that returns true if fileio

In addition drivers should be able to check for this in queue_setup() to
return an error if an attempt is made to read() or write() with
V4L2_FIELD_ALTERNATE being configured. This is illegal (there is no way
to pass the TOP/BOTTOM information around using file I/O).
However, in order to be able to check for this the init_fileio function
needs to set q->fileio early on, before the buffers are allocated. So switch
to using internal functions (__reqbufs, vb2_internal_qbuf and
vb2_internal_streamon) to skip the fileio check. Well, that's why the internal

The application should really always fill in bytesused for output
buffers, unfortunately the vb2 framework never checked for that.
So for single planar formats replace a bytesused of 0 by the length
of the buffer, and for multiplanar format do the same if bytesused is
0 for ALL planes.
This seems to be what the user really intended if v4l2_buffer was
just memset to 0.
I'm afraid that just checking for this and returning an error would
break too many applications. Quite a few drivers never check for bytesused
at all and just use the buffer length instead.

The videobuf2-core did not zero the 'planes' array in __qbuf_userptr()
and __qbuf_dmabuf(). That's now memset to 0. Without this the reserved
array in struct v4l2_plane would be non-zero, causing v4l2-compliance
errors.
More serious is the fact that data_offset was not handled correctly:
- for capture devices it was never zeroed, which meant that it was
uninitialized. Unless the driver sets it it was a completely random
number. With the memset above this is now fixed.
- __qbuf_dmabuf had a completely incorrect length check that included
data_offset.
- in __fill_vb2_buffer in the DMABUF case the data_offset field was
unconditionally copied from v4l2_buffer to v4l2_plane when this
should only happen in the output case.
- in the single-planar case data_offset was never correctly set to 0.
The single-planar API doesn't support data_offset, so setting it
to 0 is the right thing to do. This too is now solved by the memset.
All these issues were found with v4l2-compliance.
