Two code fixes, two doc fixes

Two vb2 patches: one fixes outdated comments, one fixes a poll bug w.r.t. output streams (found while adding output streaming support to qv4l2).

One v4l2-ctrls enhancement: simplify how controls are set from within the kernel and add a function to set a string controls.

One DocBook clarification how data_offset works.

Regards,

Hans
