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 two DVB demux callbacks and ioctls that aren't documented
and aren't used at all by the DVB core or by any DVB driver upstream.

Let's comment out the code for those two ioctls and remove on some
future version.

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outdated.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.

Previously, the macro DVR_FEED, which is used to recognize and filter
out duplicate packets going to the DVR device, used the TS_PAYLOAD_ONLY
flag to identify a packet's destination.

This kind of filtering was introduced by the following two changesets:

Now, that it is possible to record TS PIDs using the demux device by
setting the output type to DMX_OUT_TSDEMUX_TAP, checking TS_PAYLOAD_ONLY
is not sufficient anymore. Therefore another flag, TS_DEMUX, is added to
specify the output type of a feed.

This allows multiple clients to filter the same TS PID on a demux device
simultaneously.

Fix a bug in the software demux which causes large MPEG sections to be lost
when they follow very small sections.

The problem happens when two sections begin in the same transport packet.  The
dvb_demux code resets its buffer only before the first of these sections.
This means that when the second (or subsequent) section begins, there is up to
182 bytes of buffer space already used.  If the following section is close to
the maximum size, it currently won't fit in the (4096-byte) buffer and is
thrown away.

The fix is simply to enlarge the buffer by the size of one transport packet
and correct one usage of the SECFEED_SIZE definition where what is really
meant is the maximum size of a section.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
