ellFree vs ellFree2

[Dirk Zimoch <dirk.zimoch@psi.ch>]

Hi gurus,

I just found that the function ellFree does not exist any more in EPICS 
base 3.14.11. It has been replaced with a macro and the function 
ellFree2. Unfortunately, that means that binaries compiled with 3.14.8 
cannot run with a 3.14.11 library. Until 3.14.8, the libraries were 
always backward compatible. (Binary compatible!, not only source code 
compatible).

I looked for a good reason for this change but I could not find any code 
in base that calls ellFree2 (expect for the test code). Can someone 
please tell me what was the reason for this incompatible change?
