You should need to change anything in the callers if you made
"handle" an instance of GEOSContextHandleInternal_t class.
It should be enough to change initGEOS_r to do

    extHandle = new GEOSContextHandleInternal_t();

instead of

    extHandle = malloc(sizeof(GEOSContextHandleInternal_t));

And finishGEOS_r to do:

    delete extHandle;

instead of 


PS: if you're comfortable with git, consider forking from the official
    git mirror: https://github.com/postgis/postgis/
