Sorry for the noise...

Revert the Codec Kit.

All of Barrett's individual reverts have been squashed into this
one commit, save a few actual bugfixes.

http_streamer: API update

Codec Kit: Introduce declarative macro with version and name

* Namespaces protect symbols, I didn't consider that when adding
the BCodecKit namespace, so, the AddOnManager complained that
instantiate_plugin() was missing. A macro is introduced that allow
plugins to specify it's className, version and name, this ease
the declaration of the plugin symbols, otherwise the function
should have been declared inside the BCodecKit namespace which
we would like to avoid.
* The code is also more future proof, since in future the AddOn manager
can begin to check for plugin versions.

Codec Kit: Move plugins to new class names

http_streamer: Use MediaDebug.h

http_streamer: Fix different issues

* Cleanup object management.
* Remove Close() and use the destructor in place.
* Release listener sem on exit.
* Return when there's a request mismatch.
* Add some debugging.
* MediaPlayer crashes are fixed as result of the patchset.

http_streamer: Sync with BAdapterIO changes

Streaming: Use const reference in place of copying

* Thanks to Markus for reporting.

Streaming: Remove any pointer BUrl argument

* There's no need to pass BUrl by pointer, this is
potentially dangerous and leaky without any advantage,
copying is definitely safer.

http_streamer: General refactor making use of new API

* Use BUrlProtocolRoster instead of BFileRequest.
* Removed HTTPMediaIO custom code that now inherits
BAdapterIO and make the whole thing more simple.
* It work with some formats (flv, mp3, mkv) but ffmpeg fail
on others (mp4, 3gp).
* GetSize needs improvements.

http_streamer: Add basic draft version
