GstBufferPool

<!-- ##### SECTION Short_Description ##### -->
Create buffers from a pool

<!-- ##### SECTION Long_Description ##### -->
<para>
A bufferpool is used to create buffers in an efficient way. En element
can maintain a bufferpool with a fixed number of buffers. This will reduce
the g_malloc and g_free overhead.
</para>

<para>
A bufferpool can also be used to implement direct access. A bufferpool can be
sent from one element to another so that the latter can directly write into
the memory of the element that maintains the bufferpool. This can greatly reduce
the number of memcpy operations.
