[base] Minor API improvement for default variation axis setting. 

* src/base/ftmm.c (FT_Set_MM_Design_Coordinates,
FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates,
FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0.

* docs/CHANGES: Updated.

- Some severe problems within the handling of TrueType Variation
Fonts were found and fixed.
- Function `FT_Set_Var_Design_Coordinates' didn't correctly handle
the case with less input coordinates than axes.

differently). Applications that use the FreeType API are not
affected.
- To reset all design axis values of a variation font to its
default values you can now say
error = FT_Set_Var_Design_Coordinates( face, 0, NULL );
This also works with functions `FT_Set_MM_Design_Coordinates'
and `FT_Set_MM_Blend_Coordinates'.
