This exposes a new property, mtu, which is used to determine the initial size of buffers from the buffer pool. If received data exceeds this, the element gracefully handles that in a manner similar to what we had previously: a large memory gets filled and reallocated at the next call to "fill". The default size is set to 1500, which should cover most use cases. With contributions from Mathieu Duponchelle <mathieu@centricular.com> https://bugzilla.gnome.org/show_bug.cgi?id=772841
