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quite out of date.
