ca89302234 test: Pool now try to reset the size
As a side effect, buffers are no longer expected to be discarded on
resize.

3b54dace2d tests: include config.h and don't include unix headers
In many cases the unistd.h includes weren't actually needed.

Preparation for making tests work on Windows with MSVC.

4b9f2966fb tests: bufferpool: fix wrong assumptions about pointers and object lifecycles
The test assumed that if a buffer has the same pointer address as
before it is in fact the same mini object and has been re-used by
the pool. This seems to be mostly true, but not always. The buffer
might be destroyed and when a new buffer is created the allocator
might return the same memory that we just freed.

Instead attach a qdata with destroy notify function to buffer
instances we want to track to make sure the buffer actually
gets finalized rather than resurrected and put back into the pool.

c740bad1a0 bufferpool: Don't stop the pool in set_config()
Don't stop the pool in set_config(). Instead, let the controlling
element manage it. Most of the time, when an active pool is being
configured is because the caps didn't change.

a8d6653037 bufferpool: Don't check size in config validation
Pools are allowed to change the size in order to adapt padding. So
don't check the size. Normally pool will change the size without
failing set_config(), but it they endup changing the size before
the validate method may fail on a false positive.

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.

6079666a71 bufferpool: Add support for reconfiguring a pool
If a pool config is being configured again, check if the configuration have changed.
If not, skip that step. Finally, if the pool is active, try deactivating it.

7691150c45 bufferpool: only release buffers with writable memory
Check if the memory is writable before releasing the buffer into the
pool again.
Add unit test for this scenario.

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.
