This patch touches on places where it shouldn't: image
files and code examples. Also, it doesn't fix all array
occurrences.

So, let's revert it.

This reverts commit ffbab694.

The timestamp field was split into rx_ts and tx_ts, and the rx/tx_status
fields were moved. Update the doc accordingly.

Also fix a bug that stated that a non-zero tx_status field signaled an
error. That's not true, since TX_STATUS_OK is 1, not 0.

While reviewing the documentation gaps on LIRC, it was
noticed that several ioctls aren't used by any LIRC drivers
(nor at staging or mainstream).

It doesn't make sense to document them, as they're not used
anywhere. So, let's remove those from the lirc header.

Unfortunately, captions are new on Sphinx for c blocks: it was
added only on version 1.3. Also, it were already bad enough
not being able to auto-numerate them.

So, let's give up and use, instead, titles before the examples.
Not much is lost, and, as a side track, we don't need to
numerate them anymore.

Within the old section hierarchy, all doc parts has been placed under
the introduction, e.g:

* Linux Media Infrastructure API
    + Introduction
        - Video for Linux API
        - Digital TV API
        - ...

With separating the introduction sibling to the other parts
we get a more common section hierarchy:

* Linux Media Infrastructure API
    + Introduction
    + Video for Linux API
    + Digital TV API
    + ...

BTW: compacting the intro text.

This patch is on top of media_tree/docs-next
