Implement support for dynamically allocated arrays.
Most of the changes concern keeping track of the number of elements
of the array and the number of elements allocated for the array and
reallocating memory if needed.

(cherry picked from commit fd5d45e6561f6f8c406b81aeddecaa11f0bd15af)
The v4l2-ctrls.c source has become much too big, so split it up
into four separate parts:
v4l2-ctrls-core.c: contains the core framework code
v4l2-ctrls-api.c: contains the uAPI interface to the framework
v4l2-ctrls-defs.c: contains the control definitions
v4l2-ctrls-request.c: contains the Request API helpers
And it adds a new v4l2-ctrls-priv.h.
No code was changed, but a number of checkpatch.pl warnings were
fixed (alignment, f == NULL -> !f, long comment block coding style,
unsigned -> unsigned int).
The copyright statements were updated as well since they were
quite out of date.
