All elements of pre-DRI_NEW_INTERFACE_ONLY are removed. This allows

1,402 lines of code to be removed from Mesa (drivers and libGL).  The
big winner is dri_util.c.

Primary changes are:

1. Remove all "deprecated" entry-points from the various structures in
dri_interface.h.

2. Rename the remaining fields to removed "version numbers."  So,
bindContext3 becomes bindContext.  Functions with "New" in the name
(e.g., CreateNewContext) were *not* changed, but that is an option.
Having "New" in the name is less annoying to me than having "3" in the name.

3. Remove all compatibility code that handles cases where the driver or
the loader is too old to support the latest interfaces.

4. Append the API version to the __driCreateNewScreen function name.
This is currently done by hand.  In the future (i.e., the next time we
make an incompatible change to the interface) we'll want to come up with
a better way to do this.  This prevents old loaders from being able to load
new (incompatible) drivers.

5. Bump the API version to 20050722.  All drivers (by way of dri_util.c)
require this version.

6. All drivers are *required* to expose GLX_SGIX_fbconfig and
GLX_OML_swap_method (or the moral equivalents).  Support for these
functions in implicit in the use of the "new" interface.

7. Some cases still exist that need to be compiled differently in a loader
or core Mesa versus in a driver.  These are identified by the define
IN_DRI_DRIVER.
