8983cce9f6 gst: GST_EXPORT -> GST_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

92d3246f76 gst: mark symbols explicitly for export with GST_EXPORT
One omission: gst_allocator_sysmem_get_type() was
exported but never in any public header file.

bd9ea8d18f doc: Fix Since: marks
There was few Since: mark missing their column. Also unify the way
we set the Since mark on enum value and structure members. These
sadly don't show up in the index.

103a40b6ce bufferpool: Add method and virtuals to set flushing state
Currently there is no other way to unlock a buffer pool other then
stopping it. This may have the effect of freeing all the buffers,
which is too heavy for a seek. This patch add a method to enter and
leave flushing state. As a convenience, flush_start/flush_stop
virtual are added so pool implementation can also unblock their own
internal poll atomically with the rest of the pool.  This is fully
backward compatible with doing stop/start to actually flush the pool
(as being done in GstBaseSrc).

194db480e0 bufferpool: Add an helper to validate config
When we call gst_buffer_pool_set_config() the pool may return FALSE and
slightly change the parameters. This helper is useful to do the minial required
validation before accepting the modified configuration.

313f01ab79 buffer: invert meaning of GST_BUFFER_FLAG_TAG_MEMORY

f22d8f08e0 bufferpool: Use TAG_MEMORY to check memory before releasing
Tag allocated buffers with TAG_MEMORY. When they are released later,
only add them back to the pool if the tag is still there and the memory
has not been changed, otherwise throw the buffer away.
Add unit test to check various scenarios.

b67be761e0 bufferpool: Reset the buffer before releasing into pool
Reset the buffer not after we acquire but before we release into the pool. This
makes sure that the pool only has buffers in a clean state and that we can set
extra metadata on buffers in the acquire method. this means that we need to
remove an argument from the method.

733e94ada8 bufferpool: add options API to bufferpool
Make it possible to query the supported options of a bufferpool and enable
options. This is a bit more generic than the API to enable metadata. The purpose
is to make it possible to add new custom config options to the configuration of
the bufferpool when supported.

Keep track if the buffer is configured and block activation when not configured
yet.

buffers are returned to the pool. We need to do this or else we might end up
with wrong buffers in the pool.

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.
