V4L2_CID_POWER_LINE_FREQUENCY control allows applications to instruct
a driver what is the power line frequency so an appropriate filter
can be used by the device to cancel flicker by compensating the light
intensity ripple. Currently in the menu we have entries for 50 Hz and
60 Hz and for entirely disabling the anti-flicker filter.
However some devices are capable of automatically detecting the
frequency, so add V4L2_CID_POWER_LINE_FREQUENCY_AUTO entry for them.

Add a new VOLATILE control flag that is set for volatile controls.
That way applications know whether the value of the control is volatile
(i.e. can change continuously) or not.
Until now this was an internal property, but it is useful to know in
userspace as well.
A typical use case is the gain value when autogain is on. In that case the
hardware will continuously adjust the gain based various environmental
factors.
This patch just adds and documents the flag, it's not yet used.

Normally no control events will go to the filehandle that called the
VIDIOC_S_CTRL/VIDIOC_S_EXT_CTRLS ioctls. This is to prevent a feedback

The patch utility doesn't work with non-binary files. This causes some

logic at Makefile to convert them back into binaries at runtime.

The av7110 uses an OSD API. Such API is not documented at all. Also,
the osd.h API uses camelCase and some other weird stuff. Also, dvb-core
doesn't recognize it.
I don't see any good reason why we should document it. It seems better
to just let it as-is. If ever needed, it is probably better to write
a different API for dvb-core.

Make sure that both ca.h.xml and ca.xml will match the same names for
the sections/links.
This way, it is now possible to identify API spec gaps:
Error: no ID for constraint linkend: ca-pid.
Error: no ID for constraint linkend: ca-pid.
Error: no ID for constraint linkend: CA_RESET.
Error: no ID for constraint linkend: CA_GET_CAP.
Error: no ID for constraint linkend: CA_GET_SLOT_INFO.
Error: no ID for constraint linkend: CA_GET_DESCR_INFO.
Error: no ID for constraint linkend: CA_GET_MSG.
Error: no ID for constraint linkend: CA_SEND_MSG.
Error: no ID for constraint linkend: CA_SET_DESCR.

Basically, in this case, no CA ioctl is described at the specs, and one
file structure (ca-pid) is missing.

Although this ioctl is only used at the av7110 driver, it is not
