[PATCH wayland 0/7] Add support for custom dispatchers

[Jason Ekstrand]

Ths patch group contains my additions for custom dispatcher support inside
libwayland.  This would allow someone to handle event and resource function
calling at runtime rather than through a list of function pointers and libffi.
The primary use case for these modifications is to enable much more flexible
binding to non-C languages.

As far as I am concerned, these patches are ready for commit.  All unit tests
pass including new ones.  Also, weston successfully builds and runs against
this version.

Concerning ABI: I can't see why any programs built against earlier versions
should break with these changes.  If patch 5 (for wayland-scanner) is omitted,
earlier version of weston built against 1.0.4 work in spite of complaining
about different sized structures in the shared object.  With patch 5, they
segfault because the version is above 1 but the dispatcher is not null.  I'm
not seeing why this happens but it may be that I don't understand ABI's well
enough.

Jason Ekstrand (7):
  Make a #define for WL_CLOSURE_MAX_ARGS instead of a magic number.
  Add a default dispatcher function and related test
  Convert wl_closure to use wl_argument and enable dispatchers
  Fill out dummy objects in tests so dispatchers will work
  Make the scanner generate version 1 wl_interface structures
  Add wl_arguments forms of wl_resource_post_event and
    wl_resource_queue_event
  Test for proper usage of custom vs. default dispatchers
