[media] bttv: Width must be a multiple of 16 when capturing planar formats
On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max
size results in a solid green rectangle being captured (all colors 0 in
YUV).
This turns out to be caused by max-width (924) not being a multiple of 16.
We've likely never hit this problem before since normally xawtv / tvtime,
etc. will prefer packed pixel formats. But when using a video card which
is using xf86-video-modesetting + glamor, only planar XVideo fmts are
available, and xawtv will chose a matching capture format to avoid needing
to do conversion, triggering the solid green window problem.

[media] media_device: move allocation out of media_device_*_init
Right now, media_device_pci_init and media_device_usb_init does
media_device allocation internaly. That preents its usage when
the media_device struct is embedded on some other structure.
Move memory allocation outside it, to make it more generic.

Those ancillary functions could be called even when compiled

All errors (new ones prefixed by >>):

Also, there's nothing there that are specific to V4L2. So, move
those ancillary functions to MC core.
No functional changes. Just function rename.
