Rename base64 routines to avoid conflict with Solaris built-in functions.
Solaris 11.4 has built-in functions named b64_encode and b64_decode.Rename ours to something else to avoid the conflict (fortunately,ours are static so the impact is limited).One could wish for less duplication of code in this area, but thatwould be a larger patch and not very suitable for back-patching.Since this is a portability fix, we want to put it into all supportedbranches.Report and initial patch by Rainer Orth, reviewed and adjusted a bitby Michael PaquierDiscussion:https://postgr.es/m/ydd372wk28h.fsf@CeBiTec.Uni-Bielefeld.DE
