[RFC 00/12] Convert all wl_resources to pointers and accessor

[Jason Ekstrand]

This series includes 1 wayland patch and 11 weston patches that convert
every instance of wl_resource inside weston to a pointer.  This series also
converts everything to use accessor functions instead of the structures
directly.

In its current state, everything compiles and runs against a version of
libwayland that does not export the wl_resource structure.  However, it is
marked RFC because I have not (and do not have the capability) to test it
in its entirety.  Specifically, I don't use any sort of
internationalization (input methods) and I don't have my laptop set up to
build XWayland.  I would very much appreciate it if people would test these
patches against these two things and verify that nothing extra breaks.

Also, There are a few things that have yet to be resolved including a bug
found by U. Artie Eoff and his integration test suite.  The bug was caused
buy a subtle change in the way we handled resources and surfaces.
Specifically, that the resource is no longer valid when the surface is in
the process of getting destroyed.  This is the same as the "invalid
arguments for leave" issue.  Once I get a good handle on this, I will send
out a patch for that issue.

Beyond that, I have a few notes here-and-there among the patches, but most
of it is routine.

Thanks,
 --Jason Ekstrand
