 161. Implement a major #include rework throughout the tree.  Also enforce it
      for all non-external builds (i.e. in-tree & SDK)  (Marc La France).
 160. Rework the building of hw/xfree86/parser to be more in line with the
      building of other server subdirectories (such as common/)
      (Marc La France).
 159. ANSIfy /xc/lib/font/builtins/, and fix warnings, whitespace & formatting
      (Marc La France).

Notes:
 - `make World` highly recommended ;-)
 - This will be further tested in the next few days.

 205. Fix off-by-one error in VGA sync pulse positions for siliconmotion, vga,
      vesa and vmware drivers;  other drivers to follow;  also see CHANGELOG 133
      (Marc La France).

 802. Licence update.
(except client-side libraries)

  99. Fixed i810 crash on vt switch due to call to Sync() while switched away
      (Andris Pavenis).
  98. Fixed MGAG550 HW Cursor (Laure-Amelie Couturie).
  97. Added Xv support to neomagic driver (Shigehiro Nomura).
  96. Implemented cross compile environment (Egbert Eich).
  95. Added AMD x86-64 architecture support (Egbert Eich).
  94. Fixed memory leaks in xkb code (Egbert Eich).
  93. Fixed several memory leaks in the config file parser and initialization
      routines (Egbert Eich).
  92. Added CardBus bridge support (Egbert Eich).
  91. Fixed strdup() define in glx (Egbert Eich).
  90. Extended xf86misc extension to support changing the mouse device
      (Egbert Eich).
  89. Replaced strdup() in xf86Configure.c with xalloc()/strcpy() to avoid
      conflicts when using internal malloc (Egbert Eich).
  88. Extended memory debugging: Added signal handler to trigger a memory
      debugger dump on SIGUSR2 when compiled with memleak support
      (Egbert Eich).
  87. Set vtSema to FALSE when suspended by APM to catch calls to 2D accel
      functions (Egbert Eich).

      (Egbert Eich).
  85. Added PnP mouse detection for PS/2, ImPS/2 and older MS serial mice
      (Egbert Eich).
  84. Fixed gamma correction code for Trident 9397 (Alan Hourihane).
  83. Fixed C&T driver to avoid initialization of video in non-linear mode
      (Egbert Eich).
  82. Changed C&T driver to allow video even if acceleration is disabled
      (Egbert Eich).
  81. Attempt to implement a more consistent handling of HW cursor in C&T
      driver (Egbert Eich).
  80. Fixed MGA driver to make HALlib work with VESA framebuffer modes
      (Egbert Eich).
  79. Reworked Rendition driver (Egbert Eich).
  78. S3 Virge driver: added minimal gap between SyncStart and HDisplay to
      avoid video lockups (Egbert Eich).
  77. Fixed memory leaks in S3 Savage driver (Egbert Eich).
  76. Modified several drivers to do int10 initialization using the
      VBE functions instead of calling int10 directly (Egbert Eich).
  75. Fixed video support and mode initialization in Silicon Motion driver,
      removed wait for v-retrace (Egbert Eich).
  74. Misc fixes to SiS driver (Thomas Winischhofer).
  73. Added support for 1400x1050 screen in Trident driver (Egbert Eich).
  72. Fixed several video issues for Trident CyberBladeXP chips (Egbert Eich).
  71. Added probe for Tseng ISA chips (Egbert Eich).
  70. Added 'KGAUniversal' option to generic vga driver which changes handling

      graphics chips) (Egbert Eich).
  69. Modified int10 code to map area between V_BIOS and SYS_BIOS instead of
        copying it. Copying causes problems if legacy devices map MMIO

  62. Added Euro symbol for hungarian kbd layout (Koblinger Egmont).

  15. Fix mouse Protocol "Auto" for SunOS (Marc La France).
  14. Relocate all driver low memory accesses (atimisc module not yet done)
      (Marc La France).
  13. Make driver I/O relocatable (atimisc, s3, sis and tseng not yet done)
      (Marc La France).
  12. PCI domain changes for SunOS/SPARC64 (Marc La France).
  11. PCI domain changes for Linux/SPARC64 (#4653, Divid S. Miller,
      Marc La France).

This is a text-only merge from Domain-branch.  Not compile tested yet.

   No wonder vgaHW didn't work on PowerPC.  It was doing inb()
to non-existent VGA registers for timing.

   As a side note, we should probably ignore the VGA_SR_FONTS flag
on PowerPC so all the drivers don't have to have special code
omitting it.  There is no VGA aperture, or if there is, I don't
know where it is at.  It sure as hell isn't at 0xA0000.

Fix C&T 69030 support so that 1280x1024@24bpp with 75Hz refresh is possible.

 462. Add a PIOOffset value plus readEnable and writeEnable function pointers
      to the vgahw rec.  The former allows vgahw to be used for VGA registers
      that are shadowed in I/O space.  The latter allow the VGA_ENABLE
      register to be accessed in similar way to most other VGA registers.
      Add vgaHWEnable() and vgaHWDisable() functions (David Dawes).

 168. Removed code that sets a chipset into graphics mode when
      saving/restoring fonts in standard vga code. This causes problems
      on some trident chipsets (Egbert Eich). [EXPERIMENTAL!]
 167. Moved KGA code that handles the H/VBlankEnd code that overscans remain
      invisible to separate functions. This way drivers have better control
      over these registers.

1279. Disable RENDER extension support in the ATI(misc) driver when mibank
      and/or shadowfb is used (Marc La France).
1278. Remove cfb & friends from the ATI driver (Marc La France).
1277. Some additional ATI PCI IDs (Marc La France).
1276. Make compilation of drivers produce the same object whether or not
      DPMS and DGA extensions are being built.  Partial changes to do the same
      for RENDER (Marc La France).
1275. Ensure `make depend` goes through the same set of subdirectories as
      `make all` does.  Allows MakefileAdditions to contain depend rule(s)
      (Marc La France).
1274. Move $(EXTRA_DEFINES) to the end of ALLDEFINES.  Ditto for
      $(CXXEXTRA_DEFINES) and CXXDEFINES.  Allows easier overrides at the
      subdirectory level (Marc La France).
1273. Add a pre-clean phase to `make World` if xc/xmakefile already exists
      (Marc La France).

+ update formatted docs
+ build & warning fixes

Cleanups.

3799. Fix all other SaveScreen() functions, and add a helper xf86IsUnblank()
      that drivers can use to interpret the SaveScreen mode values
      (David Dawes).
3798. Fix GLINTSaveScreen's use of the second argument (#3706, Michel Danzer).
