Reminiscent from the pre-loader days, were we had multiple instances of
the loader logic in separate places and one could build a "GALLIUM_ONLY"
version.
Since that is no longer the case and the loaders (glx/egl/gbm) do not
(and should not) require to know any classic/gallium specific we can
drop the argument and the related code.

At the moment if a gbm buffer is imported and the gbm buffer
has an old-style GBM_BO_FORMAT format, the import will crash,
since it's passed directly to DRI functions that expect
a fourcc format (as provided by the newer GBM_FORMAT
definitions)
This commit addresses the problem in two ways:
1) it prevents invalid formats from leading to a crash by
returning EINVAL if the image couldn't be created
2) it translates GBM_BO_FORMAT formats into the comparable
GBM_FORMAT formats.

Signed-off-by: Kristian Høgsberg <krh@bitplanet.net>
The DRM_IOCTL_MODE_CREATE_DUMB (and others) IOCTL isn't very rigorously
specified, which has the effect that some kernel drivers do not consider
the .pitch and .size fields of struct drm_mode_create_dumb outputs only.
Instead they will use these as lower bounds and overwrite them only if
the values that they compute are larger than what userspace provided.
This works if and only if userspace initializes the fields explicitly to
either 0 or some meaningful value. However, if userspace just leaves the
values uninitialized and the struct drm_mode_create_dumb is allocated on
the stack for example, the driver may try to overallocate buffers.
Fortunately most userspace does zero out the structure before passing it
to the IOCTL, but there are rare exceptions. Mesa is one of them. In an
attempt to rectify this situation, kernel drivers are being updated to
not use the .pitch and .size fields as inputs. However in order to fix
the issue with older kernels, make sure that Mesa always zeros out the
structure as well.
Future IOCTLs should be more rigorously defined so that structures can
be validated and IOCTLs rejected if output fields aren't set to zero.

Add a new winsys and target that can be used with a dri2 state tracker

loader and avoid the extra copy from the backbuffer to the shadow
frontbuffer.
The new driver is called "kms_swrast", and is loaded by gbm as a
fallback, because it is only useful with the gbm platform (as no buffer
sharing is possible)
To force select the driver set the environment variable

GBM_DRIVERS_PATH is not set.

HAVE_DRI2 enables building of code using the DRI2 interface (and possibly DRI3

HAVE_DRISW enables building of DRI swrast
HAVE_DRICOMMON enables building of target-independent DRI code, and also enables
