XF86DRI is defined by xorg-server.h, so --disable-dri in the driver
itself does exactly nothing other than not fill in the CFLAGS
and thus stop the driver from compiling.

Hey, so, remember back in the dark ages when dualhead was this
insanely wild differentiating feature? Matrox thought it was so
special, in fact, that they hid most of the implementation of it
(and a bunch of other stuff) in a binary-only blob called the
HALlib. As you'd expect it was pretty much a cut-and-paste of
the relevant Windows code, and then some open glue to keep it
working; clientlx.c is that glue.
I guess the theory was that if you don't tell people which
registers to duplicate to implement a second pipe in their own
hardware, they won't figure it out? A pretty eyeroll-worthy
idea even at the time, and definitely not something we should be
condoning anymore.
Kill it with fire, but while you're at it, untangle the hideous
mess of MGA_HAL() macros too.

First pass at merging both trees. So far, this has only been tested
on the PCI-rework build on a PCI G450.

Several places in the driver contain if-statements that test Chipset against
several different values to determine what functionality to use. Some of
these tests, HALCHIPSETS in particular, test as many as 6 different values.
This bloats the code size unnecessarilly. Instead we cache the results of
some of those tests in single bit flags stored in pMga.
These changes are similar to some changes in the pci-rework branch.
