89643dbce0 Enable VidMode extension by default though some Xservers may still be 
broken. Probably run-time check for the right VidMode version? My tests
were done with X.org 6.8.2 (VidMode 2.2)

0bce152c20 - Sync with latest B2 video_vosf.h updates. 
- Enable VidMode extension with FBDev DGA graphics.
- Factor out FBDev/XF86 DGA code.
- Fix pointer grab in fbdev DGA mode, thus fixing scrolling screens in
  lower VidModes.
- Only select VidModes that match the requested resolutions, exactly.
- Fix VideoQuitFullScreen() in non FBDev mode.

0f4440f99f Handle "screen fbdev/WIDTH/HEIGHT" to force use of FBDev DGA instead of XF86 
DGA mode. In other words, root user can now use FBDev DGA though it's always
recommended to run SheepShaver with a normal user. Increase "ramsize" bounds
in the GUI and fully migrate to new "screen" modes. Remove "windowmodes" and
"screenmodes" defaults.

5810c6a764 Use "screen TYPE/WIDTH/HEIGHT" prefs item by default on Unix systems. The 
former options (windowmodes/screenmodes) are migrated if the user uses the
GUI. Also make a note about EXPERIMENTAL state for jit68k.

abd2c5406f Add "screen" prefs item similar to Basilisk II. Don't ignore SEGV by default

d27832cb1c - Implement fullscreen DGA via fbdev access under Linux. Besides, r/w access 
to /dev/mem is required on Linux to use XF86 DGA mode. Otherwise, there is
now a fallback to fbdev.
- Forward port some features from Basilisk II (set_window_name,
disable_mouse_accel).
- Don't SIGSTOP the emulation thread on suspend since that would completely
stop the process on Linux. Use a frame buffer lock instead (as B2 does)

0bc6418ea6 Implement screen win/WIDTH/HEIGHT prefs item that overrides any other value 
for windowmodes and screenmodes. Necessary for arbitrary full screen mode
sizes.

0db0d48bf0 Avoid the use of floating-point when loading/storing from/to memory. This 
could have caused some rounding thus alterations to integer registers on
context switches when lfd/stfd instructions were used. e.g. cygwin compilers
defaulted to i686 code generation and exhibed this behaviour, you could also
see this behavior with -march=i586 -mtune=pentiumpro. GCC is perfectly right
to do those optimizations.

dd7b09ebe8 Use a mutex to protect wakeup_time instead of a semaphore, do we want some 
sort of barrier synchronisation? Anyhow, the current implementation looks
reasonable enough now when using old LinuxThreads without TLS.

XXX: in the past, the sem_post in sigsuspend_handler would not release the
calling thread thus entering into a mutual waiting condition.

663facbf97 Fix native Linux/ppc with recent enough glibc that supports TLS; r2 is used 
in that case. Tell me if I broke other arches, e.g. r13 is no longer saved
in Video and Ethernet stubs, though it seems to be OK.

Colateral feature: SheepShaver should now run on Linux/ppc64 with relevant
32-bit runtime. Native Linux/ppc64 support is harder as low mem globals are
32-bit in mind and e.g. the TLS register there is %r13, %r2 is the TOC
(PowerOpen/AIX ABI)
