two gcc warnings

VMSVGA3d: Changed the surface arrays into pointer arrays to reduce the copying requried when growing (there maybe lots of them and growing by 1 is tedious). This also means the surface pointers remain valid across growths.

VMSVGA3D: Check stage range.

VMSVGA3d: Changed the context arrays into pointer arrays to reduce the copying requried when growing (entry size > 8K, I think). This also means the context pointers remain valid across growths.

VMSVGA3D: Corrected realloc calls.

vmsvga3dCreateTexture/ogl: It's not all that needs doing here, apparently...

vmsvga3dCreateTexture/ogl: Initializing the texture memory even in the non-dirty case seems to cure the texture corruption issues. It is also an good idea to not let the guest have access to uninitialized host video memory.

The D3DXDisassembleShader API required the DirectX SDK, which we don't have handy.

VMSVGA3d: Applied patches from trivirt that among other things makes Chrome work on OpenGL hosts.

vmsvga3dSaveExec: Must set packing parameters before calling glGetTexImage.

darwin build fix.

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

DevVGA-SVGA3d-ogl.cpp: Texture (surface) load and saving (to memory) fixes. Fixed crash when loading a 1 pixel wide texture. Fixed crashes loading and saving SVGA3D_A1R5G5B5 formatted textures.

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.

logging

DevVGA-SVGA3d-ogl.cpp: More logging.

DevVGA-SVGA3d-ogl.cpp: LogFlow idAssociatedContext changes.

DevVGA-SVGA3d-ogl.cpp: recreate surfaces in vmsvga3dContextDestroy just like the windows code does, prevents several assertions around the place. We don't need a context in vmsvga3dSurfaceDestroy if there are no buffer/texture associated with the surface, so don't panic with an internal error during shutdown & reset cleanups.

Added 3D capability usage xrefs against current linux sources.

DevVGA=SVGA3d-ogl.cpp: AssertReturn -> AssertReturnStmt and free double buffer.

DevVGA=SVGA3d-ogl.cpp: Don't crash should glMapBuffer return NULL, LogRel (assert in strict) the first few occurences.

GL_MAX_CLIP_DISTANCES is larger in the 3.2-core profile on my ati, so use that.

warnings

build fix

DevVGA-SVGA3d-ogl.cpp: Fixed gcc warnings and made it build on my linux system with half busted gl headers.

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.

build fix

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

VBoxSVGAObjc.dylib: Can't work with OpenGL functions directly in the same binary as the shaderlib, it redefines a bunch of GL functions as function points.

VMSVGA3d: Reworked the 3.2 core GL profile specific code, putting it inside VBOX_VMSVGA3D_USE_OPENGL_CORE checks instead of RT_OS_DARWIN and always try get a value before falling in back on alternatives.

Missing files are in place.

VBoxSVGA3D: temporarily disable dynamic resolving of the library on non-Windows platforms until the missing parts are committed

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

VMSVGA3d/darwin: Some tweaks.

VMSVGA3d/darwin: Using the use OpenGL 3.2 Core profile works better, but there are some snags like glGetString(GT_EXTENSIONS). Addressed a bunch of warnings.

VMSVGA3d/darwin: Using the use OpenGL 3.2 Core profile works better, but there are some snags like glGetString(GT_EXTENSIONS). Addressed a bunch of warnings.

scm automatic cleanups.

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

DevVGA-SVGA3d-ogl.cpp: Moved a LogFlow statement up before the RTMemFree call on the data it logs. Some nits.

VMSVGA3D: fixed assertion

DevVGA-SVGA3d-ogl.cpp: Corrected #elif RT_OS_DARWIN and #elif RT_OS_LINUX tests to use include defined(). Made several macros safer. Addressed a couple of darwin warnings.

Devices/vmsvga: header fixes
