[PULL] dtors-v2: simple clients and toytoolkit

[Pekka Paalanen]

Hi Kristian,

I've been playing a lot with Valgrind the last week, and here are some
results. This patch set adds destructors to toytoolkit so we explicitly
release memory we allocate. To actually Valgrind that, I added an exit
key binding to resizor and used that, since resizor is possibly the
simplest toytoolkit application.

The difference in the Valgrind reports between "resizor: add exit key
and cleanups" commit and dtors-v2 is:

 vvv LEAK SUMMARY:
-vvv    definitely lost: 1,680 bytes in 12 blocks
-vvv    indirectly lost: 203,688 bytes in 129 blocks
+vvv    definitely lost: 192 bytes in 1 blocks
+vvv    indirectly lost: 0 bytes in 0 blocks
 vvv      possibly lost: 0 bytes in 0 blocks
-vvv    still reachable: 7,091 bytes in 17 blocks

+vvv    still reachable: 2,267 bytes in 8 blocks
+vvv         suppressed: 1,187,441 bytes in 30,798 blocks
 vvv 
-vvv ERROR SUMMARY: 12 errors from 12 contexts (suppressed: 22369 from 189)
+vvv ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 44292 from 190)

Lots of custom suppressions were used to catch leaks and errors in
Mesa, libxkbcommon, cairo, glib, gdk, and pixman.

In addition, I first ran the simple clients with Valgrind and fixed
everything I could. simple-shm is totally Valgrind-clean now, and the
only Valgrind reports on simple-egl are from Mesa.

The following changes since commit 7bb92f0c0309d7487c5275b4171ed28bfacd96ac:
