media: Declare wildcard fields const.

This is a source compatibility break from BeOS, but should not
be an ABI one (I checked, the symbols are identical.)

Also use "= {}" in the definitions of the fields. We use this
in plenty of places in the kernel, so it should be OK for GCC2.

Media kit: Suppress -Werror=class-memaccess

* Add media_format::Clear(), media_format::Unflatten().
* Replace memset() with media_format::Clear()
* Replace memcpy() with media_format::Unflatten()

Fix #14156

MediaDefs: May be included as C not C++, so accommodate for that.

Fix a few more miscellaneous (harmless) Clang warnings.

Move old launch_media_server to deprecated file

Deprecate media_realtime_init_* functions

Add new version of launch_media_server

* Due to the needs to provide a peaceful UX, i moved out the
notifications mechanism from the Media preflet and i have
integrated it with the launch and shutdown functions of MediaDefs.h.
* This implied to introduce a new launch_media_server function
similar to the shutdown_media_server allowing to specify a custom
notification function too.
* Both functions then are reworked to send by default notifications
to the Deskbar, this was needed because in a lot of situations
the mechanism failed without correctly noticing the user.
* The one argument launch_media_server is considered to be deprecated,
the default argument is removed to mantain binary compatibility but
make new apps to automatically use the new one with just the default
arguments. This is needed due to conflicts in overloading.
* Improve notifications by indirectly extending localization
to old BeOS apps.

BMediaRoster: Add B_MEDIA_SERVER_STARTED and B_MEDIA_SERVER_QUIT

* This is done by watching to registrar notifications
and providing a minimal service to contact the
media roster in private API. The roster use this
service to automatically reconnect to the media_server.

MediaKit: Extend media_[audio|video]_header structures.

- This allows a BMediaDecoder (e.g. FFMPEG Plugin) to communicate back format
changes to its clients.
For a more thorough explanation and discussion see haiku-development mailing
list: http://www.freelists.org/post/haiku-development/Request-for-protest-Media-Kit-Extend-media-header-struct

- Backwards compatibility is taken into account and preserved by reducing the
relevant _reserved[] fields.

- Code changes that will actually make use of these extensions are due for the
following commits. As these structure extensions affect several Haiku
components (e.g. media_server, MediaPlayer, etc.) and third party apps (e.g.
StampTV, etc.) I refrain from committing them in one batch with this commit.
This should make it easier to track down bugs originating in this code
change.
(cherry picked from commit 806b6888d2dcf84b4934f8f137a48d3381864d1c)

* A BBuffer does not know where it came from, so
BBufferConsumer::BufferReceived() cannot know whom to send the "buffer is
late" notification (unless we only have a single input). To solve this, the
media_header now contains extra fields that can be used to create a
media_source object.
* Unfortunately, BBufferProducer::SendBuffer() cannot know the output either in
case there is more than one. Hence, I deprecated the existing SendBuffer()
call and moved it into "private" - IOW old sources using it won't compile
anymore under Haiku.
* I introduced a new SendBuffer() variant that also gets the media_source as
argument.
* Updated all sources (that are part of the image) to use the new variant.
* Removed some purposely commented out code in the audio mixer.
* Implemented late buffer notification, as well as late buffer handling in the
audio mixer; this is a bit of work in progress, so the debug output is left
in there.
* Some cleanup.
