Add MMP files to build libOpenVG_sw.lib which uses LINKAS to redirect to libOpenVG.dll (and the same for libEGL_sw.lib and libOpenVGU_sw.lib). Only the libEGL_sw.lib redirection isn't activated - this can't happen until there is a merged libEGL.dll which supports the OpenWF synchronisation and also implements the graphical support functions. The overall aim is to eliminate the *_sw.dll implementations, at least as a compile-time way of choosing a software-only implementation.The correct way to choose is to put the right set of libraries into a ROM with suitable renaming, and in the emulator to use the "switching DLL" technique to pick the right set. As the Symbian Foundation doesn't have any alternative implementations, we don't need the switching DLLs and we can build directly to the correct name.

__OPENGLESHEADERS_LEGACY_EGL_1_1
    
The purpose of this define is to allow the staged migration to
EGL 1.3 from EGL 1.1 taken from the perspective of OpenGL ES 1.X

If __OPENGLESHEADERS_LEGACY_EGL_1_1 is defined, then GLES/egl.h and
GLES/egltypes.h will only provide the EGL 1.1 API; in particular no 
symbols from a later version of EGL will be seen at a source code level.
This is considered to be legacy behaviour.  If
__OPENGLESHEADERS_LEGACY_EGL_1_1 is not defined, the GLES/egl.h 
and GLES/egltypes.h header files will re-direct to the system-wide 
EGL/egl.h. and EGL/egltypes.h respectively.

The use of GLES/egl.h or GLES/egltypes.h by applications is considered
legacy behaviour because applications should instead use EGL/egl.h
or EGL/egltypes.h respectively.

When this legacy behaviour is desired, the define should be placed in an
OEM-specific system-wide .hrh file.  Symbian product configurations
never set this legacy behaviour.
