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.

0986f3a64a bufferpool: Refactor stopping of the pool
Move some methods around.
Make sure we check for config parsing errors.
Increment the outstanding buffers before calling acquire so that we can be sure
that set_active() doesn't free the pool from under us.

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.

2496523b3e bufferpool: prealloc when unset flushing
According to the design doc we need to prealloc buffers when we unset the
flushing state, not in set_config.
Set the flushing state better.

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.

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...

Original commit message from CVS:
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:
Mega update of INFO, DEBUG, and ERROR subsystems, renamed with GST_ prefix.
GST_DEBUG now takes a category parameter, which is the same as GST_INFO
system.  They are now called GST_CAT_*.  All the GST_DEBUGs are set to 0
for now, we need to go and fix all these eventually.

Original commit message from CVS:

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.

9bae9d4b91 More Docs updates.
Original commit message from CVS:
More Docs updates.
Added plugin documentation. I fear we need a gstdoc implementation
that loads plugins and does introspection on them. I think we should
automatically create the docs for the pads and mime types the plugins
provide. Does anyone have enough perl knowledge to add these features? I
allready changed the C code to output the pad definitions but my perl
knowledge is too limited, for now, to implement the rest of the needed
functionality...

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.
