How's this for a solution:
Rename the functions to a consistent naming scheme, but create a header 
file
q2_compat.h  with:

#define old_name NewName

that ought to satisfy the desire to create a well understood codebase, 
with a desire to port in new code, anywhere you need the old functions 
you can just #include <q2_compat.h>
