There is a provision at the dvb_demux.c to use a vmalloc'ed
circular buffer, enabled via an extra #ifdef option that it
is not at Kconfig. Enabling it will only make the Kernel to
allocate/deallocate such buffer, but no code would actually
use it. So, no practical effect, except for sparing some
memory without any good reason.
So, get rid of such dead code.

demux.h was lacking documentation for the DMX_FE_ENTRY macro:
./drivers/media/dvb-core/demux.h:511: WARNING: c:func reference target not found: DMX_FE_ENTRY
While here, get rid of unused parameters and fix a few minor issues

The conversion from DocBook required some fixes:
- Now, the C files with the exported symbols also need to be
added. So, all headers need to be included twice: one to
get the structs/enums/.. and another one for the functions;
- Notes should use the ReST tag, as kernel-doc doesn't
recognizes it anymore;
- Identation needs to be fixed, as ReST uses it to identify
when a format "tag" ends.
- Fix the cross-references at the media controller description.

Move the contents of the media section at
DocBooks/DocBook/device-drivers.tmpl to a new ReST book.
For now, the contents is kept as-is. Next patches will fix
the warnings and add cross-references that were removed due to
the conversion.

The dvb demuxer code uses a 'struct timespec' to pass a timeout
as absolute time. This will cause problems on 32-bit architectures
in 2038 when time_t overflows, and it is racy with a concurrent
settimeofday() call.
This patch changes the code to use ktime_get() instead, using
the monotonic time base to avoid both the race and the overflow.

The DocBook description of this header has two issues:
- It calls the Kernel ABI as API, instead of kABI;
- It mentions that the DVB frontend kABI is not described
within the document. As this will actually generate a
single DocBook, this is actually not true, now that
the documentation for the frontend was added.
So, fix both issues.

Classify the functions at the DVB core per API. That makes easier
to understand how they're related to the userspace API.

It is better to keep the documentation overview at the header file,
as this makes easier for developers to remember to fix when needed.

While we can't document #defines, documenting enums are
well supported by kernel-doc. So, convert the bitmap defines
into an enum.

The usage of #define at the kABI is fine, but it doesn't
allow adding a proper description. As those defines deserve
a proper documentation, let's convert them into an enum and
document them at device-drivers DocBook.

The dvb/kdapi.tmpl has already an extensive documentation about

The DVB core has a provision for other frontend sources, but no
drivers use it. The kdapi.xml contains provision for some other
frontend source types, but it is not in sync with the code.
So, remove the unused types and sync both files.

This enum is not actually used anymore. The only value used from
the enum is DMX_OK, passed as a parameter on two callbacks.
Yet, this value is not used anywhere. So, just remove it.

There are two callbacks still not documented:
.//drivers/media/dvb-core/demux.h:422: warning: No description found for parameter 'get_pes_pids'
.//drivers/media/dvb-core/demux.h:422: warning: No description found for parameter 'get_stc'
The purpose of first one is clear. The second one is used only
on the obsolete av7110 driver, and its purpose is not clear,
as it just returns a 64-bit word from the firmware to userspace.
Let's document get_pes_pids and mark get_stc as private, adding
a comment to not use it, while this is not documented.

There are a few inconsistencies between the old documentation
that got imported into the header and the current status.
Update them, and use the proper doc-nano nomenclature for
struct artuments "@", instead of foo().

The DocBook/media/dvb/kdapi.xml contains the description of
the kABI for DVB. The problem is that, by being maintained
on a separate file and not being updated for years, it got
outdated. So, for example, some callback parameters were
changed, but the DocBook were still using the old stuff.
As a first step to fix it, let's move the documentation of
struct dmx_demux into demux.h and fix the parameters used
there.
For now, don't document any other field nor touch the
descriptions that got moved, letting this job to other
patches. That makes easier to review the patch.
PS.: Please notice that an additional patch will be needed
in order to fix the return values (some uses non-existent
return codes) and to the functions and callbacks mentioned at
the descriptions.

"enum dmx_ts_pes" and "typedef enum dmx_pes_type_t" are just the
same enum declared twice, since Kernel (2.6.12). There's no reason
to duplicate it there, and sparse complains about that:
drivers/media/dvb-core/dmxdev.c:600:55: warning: mixing different enum types
So, remove the internal define, keeping just the external one.
Internally, use only "enum dmx_ts_pes", as it is too late to drop
dmx_pes_type_t from the userspace API.
