glGetString(GL_VERSION) must not depend on locale -> Fixed in SVN

With LANG=fr_FR, glGetString(GL_VERSION) returns "2,0 Chromium 1.9" instead of "2.1 Chromium 1.9"
It's not visible with glxinfo since there is no setlocale call, but it makes gnome-shell segfault on start : clutter uses a NULL pointer when trying to call glBlendEquation (it only sets the pointer if it detects OpenGL >= 1.2, and it doesn't support the comma so detected version is 0.0).
In src/VBox/Additions/common/crOpenGL/pack/packspu_getstring.c :
- in packspu_GetString, using sprintf with "%.1f Chromium %s" depends on the language
- in GetVersionString, usage of crStrToFloat is probably wrong since the string uses '.' (I did not test, but I suppose "2.1" is converted to 2.0f here)
In src/VBox/GuestHost/OpenGL/state_tracker/state_limits.c :
- in crStateComputeVersion, same thing as above, CR_OPENGL_VERSION_STRING is "2.1", which doesn't work with crStrToFloat(atof) for all languages
