Add `FT_Done_MM_Var'. This is necessary in case the application's memory routines differ from FreeType. A typical example is a Python application on Windows that calls FreeType compiled as a DLL via the `ctypes' interface. * include/freetype/ftmm.h, src/base/ftmm.c (FT_Done_MM_Var): Declare and define. * docs/CHANGES: Updated.

- On platforms using the `configure' script, the installed
`ftoption.h' file now correctly reflects configuration options
like `--with-harfbuzz'.
