various updates to build with xorg-server 21.1.3.

- the s3, tga, and trident drivers use old functionality and are disabled
- dixmods/fb is removed, main fb has all these now (we retain our revert
of an upstream change here.)
- adjust source lists as necessary
- remove vbe module, now part of int10
- use -lxcvt
- misc clean up
- ramdac loses IBM, BT and TI support (this is one of the problems for
the disabled drivers, but also some structures in RamDac.h are gone
entirely, not copied anywhere.)
- old apm code is gone, all bsd uses pm_noop. now

this probably require a clean build in at least xorg-server and the
drivers, and perhaps the DESTDIR as well. will update src/UPDATING with
details when they are fully known.

build updates for xorg-server 1.20.3:
- moved/removed/new files
- don't define HAVE_XORG_CONFIG_H or HAVE_DIX_CONFIG_H if using
${X11FLAGS.DIX} -- already included.

put glxvnd into glx itself for now.

branches: 1.14.12; 1.14.14;
set XFree86LOADER for all xorg-server driver builds again,
it's still needed for many drivers and would normally be
set in xorg-server.h.

delete dead code. fix DIX flags for xorg-server 1.18 build after the
no longer installed dix-config.h

various updates:
- port pkgsrc libxshmfence patches
- Xextbuiltin/module is no longer a thing, make it normal
- always need xorg-config.h/xorg-server.h for server components now
- add present, damage, render, Xi, dri, pixman, extension where needed
- fix various CPPFLAGS issues
- deal with moved sdksyms.sh

round do of reach over updates for xorg-server 1.18. again, untested,
but this should be much closer to complete for the necessary changes.

first merge of xorg-server 1.18.4 reach over. not tested, and
missing at these new subdirs, some which may not be needed:

dri2
glamor
hw/xfree86/drivers/modesetting
hw/xfree86/parser
present
pseudoramiX

branches: 1.9.28;
XXX: use -Wno-error for files that use old foostr.h includes that now have
XXX: #warning's in them.

actually build glx extension.

build updates for xorg-server 1.6.

upgrade the build framework for xorg-server 1.6.

this doesn't quite work yet. Xvfb and Xnest attempt to link but
have missing symbols. Xorg doesn't build all its components yet.

branches: 1.5.2; 1.5.4; 1.5.10;
make sure libdixmods (linked into the Xorg server) is aware of MITSHM and
other server extensions.

build and install the libGLcore server module

descend into GL/glx and build the libglx.a archive and the libglx.so
extension module.

branches: 1.2.2;
stop using XSERVERINCDIR since it was referencing src/x11 reachover
this is not correct for xorg reachover

build all the dixmod parts, completing all the interesting subdirs
of hw/xfree86 i believe.
