Revert the Codec Kit.

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

media_plugins: Rework to use the BCodecKit namespace

HTTPMediaIO: fix crash on exit.

- Remove custom BUrlContext, use the shared one to simplify ownership
management. This means all HTTP media streams in an application share
the same context (including cookies), however.
- Fix deletion of the BUrlRequest object, which cannot reliably happen
before the thread has exited. RequestCompleted is too early.

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: Enforce safeness in constructor/thread

* Wait for the thread to exit.
* Update size from the data thread.

http_streamer: Implement IsRunning, more reliability

* The init sem is released also when the request is completed
to be sure the backend doesn't lock on us.
* Implement IsRunning relying on BUrlRequest::IsRunning.

http_streamer: Mutable flag is chosen at runtime

* BeOS Radio now works.

http_streamer: Refine init, set static timeout

* When in Open() the plugin wait for the first buffer
or return an error if timeout expires.
* Make size retrieve more reliable.

http_streamer: Sync with BAdapterIO changes

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.

HTTPMediaIO: Implement SetSize and GetSize

* SetSize requests are denied where GetSize return the request
lengths. Note that flags are changed accordingly.

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
