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.
