89121c18e5 bufferpool: make the default behaviour to wait
The most common case is to not specify any flags when doing the allocation. Make
the allocation from a pool with a maximum amount of buffers block by default for
this reason.

a55bc30f81 buffer: add pool to buffer structure
Keep a pointer to the bufferpool. Release the buffer to the pool when
finalizing. Make sure the pool sets itself as the pool member of buffers that it
sends out.

e566910a18 bufferpool: Rework buffer management a little
Add start/stop methods to allow for bulk allocation of buffers.
Free buffers only when all outstanding buffers returned.
Make things more threadsafe wrt flushing and starting/stopping by
keeping track of start and stop method calls.

419a01af0f bufferpool: memory management cleanups
Use a lock to protect concurrect execution of set_config and set_active.
Start freeing the buffers when flushing and all buffers are returned to the
pool.
Make a copy of the config to avoid crashing with concurrent access.

9b1cadc329 bufferpool: more updates
Keep track if the buffer is configured and block activation when not configured
yet.
Keep track of outstanding buffers and disallow configuration when not all
buffers are returned to the pool. We need to do this or else we might end up
with wrong buffers in the pool.
Add return value to set_active.
Small cleanups. Fix finalize.

dd16af7a6c bufferpool: rename 'flushing' to 'active'

the other gstreamer name conventions

0caa41e173 bufferpool: use GstStructure to configure the pool
Use a GstStructure to provide the pool with the right configuration. Also
provide some helper methods to configure such a structure.
don't pass the config in alloc_buffer, pool implementation will already have
parsed it during set_config.
Update defs

- implemented refcounting on GstData
- implemented new buffer code based on Company's work in the EVENTS2 branch
- added boxed types for GstData/GstEvent/GstBuffer/GstBufferPool
- added refcounting to bufferpools and events
- use lockfree allocation for buffers
- simplified the clock, use lockfree allocation
- use GQueue in GstQueue for faster access to the tail element
- update core plugins to the new event API

cccc097ca5 API docs. revived _buffer_ref_by_count fast types for scheduler and bin.
Original commit message from CVS:
API docs.
revived _buffer_ref_by_count
fast types for scheduler and bin.
error checking on plugin features;
removed some prototypes that were not implemented (gst_pipeline_iterate
comes to mind)
remove gst_pad_event until we know what it's supposed to do.
remove sinesrc, it wasn't compiles anymore, so...
updates to various elements that used the old event API.

The bufferpool api has changed. Check gstbufferpool.h to see the updated
interface.

Also, the default bufferpool implementation has been finished somewhat. Take a
look at speed.c to see an example of its use, when I get the plugins committed.

Original commit message from CVS:
Header cleanup: try to include as little as possible; this will probably
speed up compilation a bit.
changed the .c files to use #include "..."
Fix for the 'plugins are loaded twice' bug.
Fix 22186: GstObject flags are now used everywhere. Added *_FLAG_LAST so
elements do not use the same flags. Added some padding in the flag enum
for future expansion.

d9701bf8a7 Added the bufferpool handler.
Original commit message from CVS:
Added the bufferpool handler.
This object is able to generate buffers and is passed between elements to
exchange buffers. Elements can also use this pool to efficiently generate
output buffers.
