kate: remove plugin

Browse source 
Bitrotten and not really used in the wild.

The actual render library (libtiger) is not just unmaintained
but the upstream location has disappeared, and it's also not
even packaged by e.g. debian/ubuntu.

Closes #3071

Kate is a free codec for text based data, which can also carry images.
It is typically used to create overlays on a video.
libkate, a codec for Kate streams, is required to build this plugin:
http://libkate.googlecode.com/
libtiger, a rendering library for Kate streams, is optional:
http://libtiger.googlecode.com/
The Kate plugin contains various elements to manipulate Kate streams:
- katedec: decodes Kate streams to text and SPU images
- kateenc: encodes Kate streams from text and SPU images
- kateparse: parses Kate streams
- katetag: allows changing metadata in Kate streams
- tiger: decodes and renders Kate streams using libtiger (needs libtiger)
More information about Kate can be found at:
http://wiki.xiph.org/index.php/OggKate

/**
* SECTION:element-kateparse
* @title: kateparse
* @short_description: parses kate streams
* @see_also: katedec, vorbisparse, oggdemux, theoraparse
*
* The kateparse element will parse the header packets of the Kate
* stream and put them as the streamheader in the caps. This is used in the
* multifdsink case where you want to stream live kate streams to multiple
* clients, each client has to receive the streamheaders first before they can
* consume the kate packets.
*
* This element also makes sure that the buffers that it pushes out are properly
* timestamped and that their offset and offset_end are set. The buffers that
* kateparse outputs have all of the metadata that oggmux expects to receive,
* which allows you to (for example) remux an ogg/kate file.
*
* ## Example pipelines
*
* |[
* gst-launch-1.0 -v filesrc location=kate.ogg ! oggdemux ! kateparse ! fakesink
* ]|
* This pipeline shows that the streamheader is set in the caps, and that each
* buffer has the timestamp, duration, offset, and offset_end set.
*
* |[
* gst-launch-1.0 filesrc location=kate.ogg ! oggdemux ! kateparse \
* ! oggmux ! filesink location=kate-remuxed.ogg
* ]|
* This pipeline shows remuxing. kate-remuxed.ogg might not be exactly the same
* as kate.ogg, but they should produce exactly the same decoded data.

/**
* SECTION:element-katetag
* @title: katetag
* @see_also: #oggdemux, #oggmux, #kateparse, #GstTagSetter
* @short_description: retags kate streams
*
* The katetag element can change the tag contained within a raw
* kate stream. Specifically, it modifies the comments header packet
* of the kate stream, as well as the language and category of the
* kate stream.
*
* The element will also process the stream as the #kateparse element does
* so it can be used when remuxing an Ogg Kate stream, without additional
* elements.
*
* Applications can set the tags to write using the #GstTagSetter interface.
* Tags contained within the kate stream will be picked up
* automatically (and merged according to the merge mode set via the tag
* setter interface).
*
* ## Example pipelines
*
* This element is only useful with gst-launch-1.0 for modifying the language
* and/or category (which are properties of the stream located in the kate
* beginning of stream header), because it does not support setting the tags
* on a #GstTagSetter interface. Conceptually, the element will usually be
* used like:
* |[
* gst-launch-1.0 -v filesrc location=foo.ogg ! oggdemux ! katetag ! oggmux ! filesink location=bar.ogg
* ]|
*
* This pipeline will set the language and category of the stream to the
* given values:
* |[
* gst-launch-1.0 -v filesrc location=foo.ogg ! oggdemux ! katetag language=pt_BR category=subtitles ! oggmux ! filesink location=bar.ogg
* ]|
*
