9c9a810c41 Media Kit: BBufferCache: if not reclaimed, only mark the buffer for deletion
hrev53379 clears the buffer cache for disconnected clients, and also delete buffers.
This is too early (see #15263, media_addon_server crash), and should only happen
after the buffer is recycled. This can be resolved by abusing the fFlags field of
BBuffer to mark the buffer for deletion, and mark the buffer to be reclaimed.
Some BBuffers don't reside in the SharedBufferList, so we have to mark them as to
be reclaimed. For those in the SharedBufferList, call a new RemoveBuffer(), which
can check whether the buffer is still to be reclaimed. For reclaimed BBuffers,
delete them right away, others can be marked for deletion.
fixes #15606 #15263, possibly #15433

1cc20d8231 BBufferGroup: Check for duplicated buffer id
* This exclude some possible cheating cases.
  It impose to have only a buffer_id per thread,
  so instances will not be duplicated if not needed.

2f9ed888a2 * The SharedBufferList is now only cloned once in a team, no longer once for
each buffer, and once for each buffer group.
* Also, SharedBufferList::Get() now gets the area to clone from itself, if
  necessary, the caller no longer has to provide it.

9dec231042 Sorry for this large commit in advance; it's not really possible to divide this
into smaller parts:

media_addon_server:
* Removed (broken) use of (broken and inefficient) home-brewn Map, and List
  classes. This also fixes a crash on shutdown when used with the malloc_debug
  implementation. It's using stl::vector, and stl::map now instead.

_shared_buffer_list:
* Renamed _shared_buffer_list to SharedBufferList, and put it into the BPrivate
  namespace. Also, made a class out of it.
* Separated shared buffer list creation from cloning.
* Enlarged maximum number of buffers to something that is not that evil, but
  actually uses the space it has (ie. is a useful multiple of
  shared_buffer_info that fills a multiple of B_PAGE_SIZE as much as possible).
* No longer drops into the debugger if the
* The list that is currently used is very inefficient for the features it
  provides though (no change there).

_buffer_id_cache:
* Renamed to BufferCache, and put it into the private namespace
* It now deletes its buffers on deletion; since the BBufferConsumer will be
  gone, too, at this point, there is little chance that there are still buffers
  in use.
* Also, it's now using std::map instead of the (see above) Map class.

BBuffer:
* Got rid of the fBufferID member.

Misc.:
* Got rid of the global "team" variable; the media kit is now using the
  private app kit's current_team() now.
* Added a lot of missing error checks (mostly memory allocations).
* Renamed fields like "flavorid" to flavor_id, renamed "dfi_*" fields to
  something more detailed.
* Moved ServerInterface.h from src/servers/media/ to headers/private/media.
* Notifications.h was not self contained.
* Added missing licenses.
* Lots of cleanups, and coding style fixes.

What this doesn't fix:
* Bug #4954 which started all this (this comes next, though)
* Deinitialization is broken, as the PortPool is uninitialized too early, and
  still used afterwards.
* The strange add-on monitoring code in the media_addon_server
