I don't like the fribidix_ prefix.  What if you'll need to change the
interface from 1.* to 2.*?  Will we have to use fribidixx_ then?

I suggest to require people, who need the old interface, to define a macro
(say FRIBIDI_0_9_0_INTERFACE_WANTED) before #include <fribidi.h>. The
macro will cause all functions with incompatible interfaces to be
redefined as macros, which eventually invoke functions with the new
interfaces.

fribidi.h will include the following (for each function whose interface
has changed):

#ifdef FRIBIDI_0_9_0_INTERFACE_WANTED
void fribidi_old_func(a,b,c);
#define fribidi_func(a,b,c) fribidi_old_func((a),(b),(c))
#endif /* FRIBIDI_0_9_0_INTERFACE_WANTED */

fribidi.c will include the following:

#ifdef FRIBIDI_0_9_0_INTERFACE_WANTED
#undef fribidi_func
void fribidi_old_func(a,b,c)
{
  fribidi_func(a,strlen(a),b,c)
}
#endif /* FRIBIDI_0_9_0_INTERFACE_WANTED */
void fribidi_func(a,len_a,b,c)
{
  ... actual code ...
}


DISCLAIMER:  I haven't actually tried to compile or run the above.
