The media_dbg() in error paths can modify the errno value, leading to
the wrong error (or no error at all) being returned. Fix this by reading
the errno value before calling media_dbg().

Most parser functions take a **endp argument to indicate the caller
where parsing has stopped. This is currently only used after parsing
something successfully. This patch sets **endp to the erroneous
position in the error case and prints its position after an error
has occured.

The following errors usually resulted in the same 'Unable to parse
format' message:
- syntax error in format description
- the requested pixel code isn't supported
Add more detailed error messages to give the user a clue what is going
wrong.

src/mediactl.c needs ctype.h for its use of isspace().
src/v4l2subdev.c needs stdlib.h for strtoul() and ctype.h for isspace()
and isupper().

V4L2 selection targets will replace V4L2 subdev selection targets in the
near future. As the targets are guaranteed to be the same and the chance is
anticipated very soon, replace the subdev targets with more future-proof
V4L2 targets.

More flexible and extensible syntax for format which allows better usage
of the selection API.
Continue supporting the old syntax but remove the documentation for it. It
was not supported in an official release and its use is thus deprecated.

Support the new selections API for crop. Fall back to use the old crop API
in case the selection API isn't available.

Mail sent to all contributors on 2011-09-30:
Hi everybody,
Sakari made me realize today that the media-ctl project is still licensed
under the GPL v2+ license, while I would have sworn that we had switched to
LGPL a long time ago.
I would like to relicense the media-ctl project under the LGPL v2.1+, to allow
LGPL-compatible applications and libraries (such as libv4l for instance, or
its plugins) to link to libmediactl and libv4l2subdev.
As you all have submitted patches that are now included in the media-ctl
project, I'm requesting your permission to proceed with the license change.

Hi Laurent,
No problem for me. You can go ahead, if everyone else agrees of course.
Regards,
Sergio

I'm in favour of the change, actually I think it's next to mandatory for the
library to be useful in a way it was intended.
Cheers,

I have no objections.
But I didn't remember libudev exact license... Ah, okay, it's licensed
under LGPLv2.1+.

Add debugging handler to media_device that may be used to redirect all debug
formatting to user-supplied function. fprintf will do, and that's what
media-ctl test program will use.

This makes format parsing a part of the libv4l2subdev and thus available on
all who use the library.
