Add support for the new DRM memory manager.

Some code are duplicated with the new libdrm.
Once this code has been released with xserver,
it can be removed.

See the man page for new options and backwards
3D driver compatibility.

+Enable support for the legacy i915_dri.so 3D driver.
+This will, among other things, make the 2D driver tell libGL to
+load the 3D driver i915_dri.so instead of the newer i915tex_dri.so.
+This option is only used for chipsets in the range i830-i945. 
+Default for i830-i945 series: Enabled for i915 drm versions < 1.7.0. Otherwise
+disabled. 
+Default for i810: The option is not used.
+Default for i965: The option is always true.

+.BI "Option \*qAperTexSize\*q \*q" integer \*q
+Give the size in kiB of the AGP aperture area that is reserved for the
+DRM memory manager present in i915 drm from version 1.7.0 and upwards,
+and that is used with the 3D driver in Mesa from version 6.5.2 and
+upwards. If the size is set too high to make room for pre-allocated
+VideoRam, the driver will try to reduce it automatically. If you use only
+older Mesa or DRM versions, you may set this value to zero, and
+atctivate the legacy texture pool (see 
+.B "Option \*qLegacy3D\*q"
+). If you run 3D programs with large texture memory requirements, you might
+gain some performance by increasing this value.
+Default: 32768.
