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.

Converts the dtt200u DVB USB driver over to the rc-core

generic NEC / NEC Extended signals and the switch to the newer core
enables the easy use of tools such as ir-keytable to modify the active

Fix RC5 decoding with Fintek CIR chipset
Commit e87b540be2 tightened up the RC5
decoding by adding a check for trailing silence to ensure a valid RC5
command had been received. Unfortunately the trailer length checked was
10 units and the Fintek CIR device does not want to provide details of a
space longer than 6350us. This meant that RC5 remotes working on a
Fintek setup on 3.16 failed on 3.17 and later. Fix this by shortening
the trailer check to 6 units (allowing for a previous space in the
received remote command).

Adding the header file is interesting for several reasons:
1) It makes MC documentation consistend with other parts;
2) The header file can be used as a quick index to all API
elements;
3) The cross-reference check helps to identify symbols that
aren't documented.

The function that replace references add a "\ " at the end of
references, to avoid the ReST markup parser to not identify
them as references. That works fine except for the end of lines,
as a sequence of { '\', ' ', '\n' } characters makes Sphinx
to ignore the end of line. So, strip those escape/spaces at the
end of lines.

Implement memory barriers according to Documentation/circular-buffers.txt:
- use smp_store_release() to update ringbuffer read/write pointers
- use smp_load_acquire() to load write pointer on reader side
- use ACCESS_ONCE() to load read pointer on writer side
This fixes data stream corruptions observed e.g. on an ARM Cortex-A9
quad core system with different types (PCI, USB) of DVB tuners.
