Bug Description

Here are 2 bugs that picked up in valgrind while running egl examples, which I've made sure under 1 examples that eglDestorySurface is being called on the same pointer that was created:

More debugging symbols, but can't figure out the last 3 '???'

For mir_demo_client_eglplasma:

For an SDL2.0 app:
http://paste.ubuntu.com/5983070/

They seem like memory leaks in libEGL but it is running things in mir...

To reproduce:
valgrind --tool=memcheck --num-callers=50 --leak-check=full --track-origins=yes mir_demo_client_eglplasma 2>&1 | tee mir-val.log

There appears to be 2 different leaks, but they are consistent. Even when things are cleaned up through eglTerminate and eglDestorySurface.
