which is zero by default.
perform rbtree sanity checks only when it isn't zero
because the check is very heavy weight especially when
there're many entries.
+ sorting of various XSERVER_ entries in Makefiles
+ addition of Xpmax Xdreamcast Xmacppc XSERVER_ entries
+ consistent use of != "no" instead of == "yes" changes
in the case that there's no cached entries,
if kmem_map is already up, allocate a entry from it
so that we won't try to vm_map_lock recursively.
XXX assuming usage pattern of kmem_map.
* detect and store vc2 revision. This is (likely) the important factor in
determining the proper cursor offset, so add a bit of logic that does the
right thing on my revision 0 vc2. This will have to be determined
empirically, revision by revision.
* take a stab at detecting framebuffer depth. SGI does it quite differently,
but their algorithm doesn't work, so we'll do it along the same lines as
linux.
* implement newport_mmap() for use by X. The necessary xsrc commits have been
made (with the notable exception of the config/cf changes, which probably
shouldn't go in until 4.4.0 has been imported).
Therefore lkmdispatch(LKM_E_UNLOAD) must be called to free resources in
case the load function fails.

This simplifies using ld with ${DESTDIR}/usr/lib whilst retaining the
(slightly faster) absolute links for the run-time libraries.
Per discussion on tech-toolchain.
(Side note; install(1) -l r needs the source to be prefixed with ${DESTDIR}
to operate correctly, which makes it non trivial to enable '-l r' by default
for all ${INSTALL_SYMLINK}s)
/etc/mtree/set.<set> if they are different. This should allow
installsets to operate from a pre-populated read-only DESTDIR.
Based on fix from Juergen Hannken-Illjes.
