51f76375e3 media: dvb-usb: Constify struct usb_device_id
'struct usb_device_id' is not modified in these drivers.

Constifying this structure moves some data to a read-only section, so
increase overall security.

In order to do that, struct dvb_usb_device_description (in dvb-usb.h) also
needs to be updated.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
   1983	   4240	      4	   6227	   1853	drivers/media/usb/dvb-usb/a800.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
   2079	   4144	      4	   6227	   1853	drivers/media/usb/dvb-usb/a800.o

281b21c56e media: dvb-usb: dibusb-mc: use an enum for the device number
The device number is currently a value that needs to be the same
on two separate tables, but the code doesn't actually enforce it,
leading to errors as boards get added or removed.

Fix it by using an enum.

577a7ad33a media: docs: move driver-specific info to driver-api
Those documents don't really describe the driver API.

Instead, they contain development-specific information.

Yet, as the main index file describes the content of it as:

	"how specific kernel subsystems work
	 from the point of view of a kernel developer"

It seems to be the better fit.

99e44da792 [media] media: change email address
Soon my dibcom.fr/parrot.com-address won't respond anymore.
Thus I'm replacing it. And, while being at it,
let's adapt some other (old) email-addresses as well.
