Message : * src/*: Add checks for parameters of API functions where missing. `API functions' are functions tagged with `FT_EXPORT_DEF'. Besides trivial fixes, the following changes are included, too. * src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set error code if no service is available. * src/base/ftinit.c (FT_Done_FreeType): Change return value for invalid `library' parameter to `Invalid_Library_Handle'. * src/base/ftobjs.c (FT_New_Size): Change return value for invalid `asize' parameter to `Invalid_Argument'. * src/base/ftoutln.c (FT_Outline_Copy): Change return value for invalid `source' and `target' parameters to `Invalid_Outline'. (FT_Outline_Done_Internal): Change return value for invalid `outline' parameter to `Invalid_Outline'.
