 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.

 283. First phase of dynamic configuration (David Dawes, S. Lussos,
      Michael Dawes, J. D. Darling, X-Oz Technologies).

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

IRIX build and warning fixes

Add/update copyright and license notices.

Typo noticed by Joe Moss

  34. Add a new request to the XF86Misc extension that allows a client
      to send an arbitrary message to the DDX, which in turn can send the
      message to the driver.  The driver may also send a string back.
      An example of this is implemented for the radeon driver (#5518,
      Joe Moss).

  26. Updates for building on OS/2 (#5650, Frank Giessler).

 493. Add a request to the XFree86-Misc extension for querying the
      X server's config file, module path, and log file name (#5456, Joe Moss).

 319. Moved LdPreLib define after the vendor/OS specific config files
      as it may depend on setting done there (Egbert Eich).
 318. Several fixes for cross compile environment (Egbert Eich).
 317. Added code to allow for building of static only libraries with
      -fPIC for platforms which require it (Egbert Eich).
 316. Added '-m32' to gcc flags as default for ia32 builds when gcc version
      is >= 3.1. This allows building a 32 bit Version of X on 64bit x86-64
      (Egbert Eich).
 315. Changed direct calls of ld to 'gcc -nostdlib' for Linux (Egbert Eich).
 314. Changed calls to as to 'gcc -c -x assembler-with-cpp' for Linux
      (Egbert Eich).
 313. Added '-fno-strict-aliasing' flag to gcc version >= 3.1 (Egbert Eich).
      Strict requires that one address must not contain pointers to
      different types - a feature heavily used by X (Egbert Eich).
 312. Fixed a core dump problem in libXtt (?) (Egbert Eich).
 311. Removed '#pragma pack' from structures that contain function pointers
      in x86emu. This causes problems on gcc 3.1 for ia64 (Egbert Eich).
 310. Added defines for missing X types to saverproto.h (Egbert Eich).
 309. Fixed compiler warings generated by gcc >= 3.1 in mesa drivers
      (Egbert Eich).
 308. For platforms that allow both 32 and 64 bit libraries to be executed
      split Xlib i18n modules path into
      <libpath>/X11R6/lib/X11/locale/lib/common and
      <libpath>/X11R6/lib/X11/locale/lib64/common. 'lib64' has been defined
      to be the default path for 64bit shared libraries on these platforms
      (Egbert Eich).
 307. Fixed obvious typo in OMlib (Egbert Eich).
 306. Fixed code in cfb that didn't comply with C sequence rules.
      Modern C compilers tend to be more aggressive on code reordering
      (Egbert Eich).
 305. Changed arguments of NoopDDA() from VarArgs to void. Handling
      of VarArgs by gcc isn't compatible with the way it was used
      on certain platforms (Egbert Eich).
 304. Added support for 32bit pixmaps for 24bit overlay framebuffers in
      fb overlay code (Egbert Eich).
 303. Fixed kdrive to print a meaningful error message instead of just
      core dump when no matching graphics cards is found (Egbert Eich).
 302. fixed portability bug in xwd (Andreas Schwab <schwab@suse.de>)
 301. fixed X Server crash, which happended each time a proportional iso10646
      font was loaded with xtt backend (Yong Li <rigel863@yahoo.com>)
 300. Added some ARM specific fixes to compiler.h (Uli Hecht).
 299. Added a virtual 'dummy' driver (Egbert Eich).
 298. Fixed core dump when certain access functions are not set in
      xf86Bus.c (Egbert Eich).
 297. Fixed problem where SIGIO could be disabled after a server reset.
 296. Added configurable list of devices the xf86Misc extension is allowed
      to change the mouse device to (Egbert Eich).
 295. Changed default mouse type to 'auto' when generating config file
      with '-configure' (Egbert Eich).
 294. Made sure keyboard modifier settings are consistent after exit
      from DGA when the xkb extension is used (Egbert Eich).
 293. Disabled keyboard processing when Xserver is suspended by power
      management.
      This allows effective locking of laptops when stolen (Egbert Eich).
 292. Added/improved options for lockfile syncing (Egbert Eich).
 291.  Added support for backup copy of Xserver logfile (Egbert Eich).
 290. Fixed GetTimeInMillis() to use deltas instead of absolute time
      returend by gettimeofday(). This ensures time is monotonic in X
      (Egbert Eich).
 289. Fixed xf86Misc extension to allow modification of Expps2 mice
      (Egbert Eich).
 288. Made code in xf86MiscExt.c more readable (Egbert Eich).
 287. Fixed PCI CardBus bridge handling (Egbert Eich).
 286. Added code to reenable PCI bus mastering after coming back from a
      VT switch to radeon driver (Charl P. Botha <http://cpbotha.net/>)
      (Egbert Eich).
 285. Dito for r128 driver (M. Harris).
 284. Dito for glint and mga driver (Egbert Eich).
 283. Fixed double scan issues for low res modes in C&T driver (Egbert Eich).
 282. Set rgbBits to 8 for all HiQV chips in chips driver (Egbert Eich).

 278. Restructured and included Matrox's Merged Framebuffer changes
      to mga driver (Egbert Eich).
 277. G450/550 clockchip programming fixes (Matrox).
 276. Fixed HW Cursor for HALlib frame granularity (Egbert Eich).
 275. Enabling 2D accel in 24-bit for neomagic 2360 and 2380 (Egbert Eich).
 274. Added support for builtin 1024x480 mode of Sony subnotebooks for
      Neomagic driver (Egbert Eich).
 273. Fixed support for lowRes (320x240) modes in neomagic driver
      (Egbert Eich).
 272. Fixed RAC function registration in S3 driver (Egbert Eich).
 271. Added some voodoo to screen initialization of S3 driver (Egbert Eich).
 270. Fixed vbe/int10 support in SMI driver. It used to core dump
      when BIOS was not usable (Egbert Eich).
 269. Separated BRIGHTNESS and and CAPTURE_BRIGNTESS video attributes
      in smi driver: CAPTURE_BRIGHTNESS refers to the capture chip
      (ie. Philips SAA7110) while BRIGHTNESS controls the video overlay
      of the SMI chip itself (Egbert Eich).
 268. Disable automatic loading of DRI when running SUN ffb as this is
      inconsistent with other drivers (Thorsten Kukuk).
 267. Fixed Gamma/Brightness code in trident driver (Egbert Eich).
 266. Added FpDelay debugging option (Egbert Eich).

 261. Improved mouse autodetection code (Egbert Eich).
 260. Restructured int10 code so that vm86 and x86emu support can be loaded
      as modules. Implemented heuristic to try vm86 first and fall back to
      x86emu. This allows 32 bit Xservers to run on x86_64 on 64-bit kernel
      without vm86 support (Egbert Eich).
 259. Restructured elf loader: determine which section to load from elfheader
      flags (Egbert Eich).
 258. Adding RENDER Support to RAC (Egbert Eich).

      (Egbert Eich).
 256. Replacing sprintf() by snprintf() in lbxproxy to eliminate possible
      buffer overrun exploits (Egbert Eich).
 255. KP_Decimal fixes to Czech and Slovak keybards
      (Jan Holesovsky <kendy@suse.cz>) (Egbert Eich).

  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).

      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).
  86. Implemented mouse protocol detection by analyzing data stream
      (Egbert Eich).
  85. Added PnP mouse detection for PS/2, ImPS/2 and older MS serial mice
      (Egbert Eich).

  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
      left overscan to work also on chips with C&T core (ie all C&T and Intel
      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
        registers there (Egbert Eich).
  68. Implemented an extended int10 init function to allow passing flags
        (Egbert Eich).
  67. Implemented optional handling of BIOS video mode scratch area in int10

  64. Added missing commas to symbols/us_intl (Hans Lunsing).
  63. Added Ungherese (qwerty) support (Koblinger Egmont).
  62. Added Euro symbol for hungarian kbd layout (Koblinger Egmont).

 221. Add a workaround for FreeBSD to make programs (like mkfontdir) that
      are run as part of the build use the shared libraries from the build
      rather than those that may be installed on the system (David Dawes).
- Fix some things related to the new fontenc code, enable binary compatibility
  with the older interfaces by default, change the font ABI revision to 0.3
  and the Xfont shared library version to 1.4.
- Some build/warning fixes.
- Remove unused xf86Switch.c.

Summary of changes for grab removal/client-closedown key sequences:

o Changed XF86MISC_MINOR_VERSION from 4 to 5
o Added the function "int XF86MiscSetGrabKeysState(Display *dpy, Bool enable)"
  to the XF86Misc extension. The enable argument means allow or disallow the
  use of the keys Ctrl+Alt+KP_Divide or Ctrl+Alt+KP_Multiply.
  The return values are:
  MiscExtGrabStateSuccess:	success, enabled or disabled key sequences
  MiscExtGrabStateLocked:	another client already disabled the key
				sequences
  MiscExtGrabStateAlready:	call for enabling when enabled, or disable
				when disabled
o The key sequence Ctrl+Alt+KP_Divide deactivates any active keyboard/pointer
  grab, if the XF86Config option allowDeactivateGrabs is set.
o The key sequence Ctrl+Alt+KP_Multiply closes the connection for the client
  owner of any active keyboard/pointer/server grab, if the XF86Config option
  allowClosedownGrabs is set.
