6770a355ae Cirrus: Fixed redraw issue caused by misaligned bitblt region. 
If x0 + width exceeds the screen width, mark tile(s) on the left side of the screen, too.
This should finally fix issue #221.

61a35063c5 remove all ifdefs from features.h 
I'd like features bitmasks to be independent on Bochs compilation flags
so let all flags to be 'exists' even if corresponding feature is not compiled in.

04ed1e8fd2 Some more VGA timing handling chages. 
- Changing status of 'update_mode_vsync' is no longer supported at runtime.
  If disabled, changing the value is only valid between 1 and 75.
- Modify vtotal_usec if frequency to high before activating vsync_timer.

1ebe15e3fc Rewrite of the VGA timing code. 
- Added VSYNC timer handler using vertical total usec. The calling time is defined
  as vertical retrace end and it updates the CRTC start address like real VGA does.
  It also calculates the display start time used when reading the input status register.
  The VSYNC timer is disabled in Voodoo / Banshee modes.
- Improved VGA timing calculation (e.g. vertical blanking and retrace start).

6977fc05d9 VMX: adjust RFLAGS saved into guest state on VMEXIT according to VMX documentation: 
For APIC-access VM exits and for VM exits caused by:
- EPT violations
- EPT misconfigurations
- page-modification log-full events or
- SPP-related events
the value saved depends on whether the VM exit occurred during delivery of an event through the IDT ...

also handle RFlags saved if VMEXIT was caused directly by an event that would normally be delivered through the IDT

should fix #215
