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.

PostScript name is provided, not looking up special entries for
named instances.
- A new function `FT_Done_MM_Var' is provided to free the memory
returned in a call to `FT_Get_MM_Var'.
- On platforms using the `configure' script, the installed
`ftoption.h' file now correctly reflects configuration options
like `--with-harfbuzz'.
