DevVGA-SVGA3d-ogl.cpp: Attempt to deal with annoying assertions in for example vmsvga3dSurfaceStretchBlt after surfaces have been ophaned by vmsvga3dContextDestroy.

Corrected wrong assertion in vmsvga3dDrawPrimitives that would trigger all the time both texture units were active. Copied some more code from the windows version that invalidates surfaces references in context in vmsvga3dSurfaceDestroy.

simplification.

the right way to format floating point.

svga3d: log 3d capabilities.

Use PDMDevHlpGetCurrentCpuId.

VMSVGA: Use new EMT wait API.

Fixed RTSemEventMultiWaitEx call and a warning.

Improved the ugly SVGA_REG_BUSY read hack a bit.

Replaced ugly RTThreadSleep(50) on EMT with a yeild + a wait on a event sempahore that the FIFO thread will signal on when done.

VMSVGA: FIFO stats; wait on the work-to-do-semaphore instead of sleeping when we're short on data in the FIFO (rare); Signal the semaphore before entering the FIFO loop so we don't delay work unecessarily when resumed.

logging adjustments

vmsvga fifo handling optimizations.

DevVGA-SVGA.cpp: Fixed bugs in SVGA_REG_BITS_PER_PIXEL, SVGA_REG_HEIGHT, and SVGA_REG_HEIGHT write handlers that was uncovered by enabling the code in ring-0 and raw-mode contexts. The device state was changed before we decided that we needed to handle the request in ring-3, and because of the state change nothing was actually done in ring-3.

vmsvgaGMRTransfer: Display detail in buffer overflow assertions.

VMSVGA3d: Cleaning up some of the dual-profile mess, switched back to using the 2.1 profile by default.

DevVGA-SVGA.cpp: Register the I/O ports for ring-0 and raw-mode context callbacks. Changed FIFORequestSem to a cross context semaphore so we can signal it from ring-0.

Use a context configured with the legacy OpenGL profile for getting information not available when using the OpenGL32Core profile.

Dynamically resolve imports from VBoxSVGA3D.dll/dylib/so. Added some docs, some nit picking.

DevVGA-SVGA.cpp: Use RT_FROM_MEMBER.

scm automatic cleanups.

SVGA/SVGA3d: Moved hexdumps from LogFlow() to Log2(), Log3(), and Log4().

Devices/Main: vmsvga updates

Devices/Graphics/vmsvga: don't loop forver if the guest doesn't respond

Devices/Graphics: VMware SVGA II compatible graphics emulation (2D only), including the associated small API and VBoxManage changes, contributed by trivirt AG.
