In transam.h, don't expose static inline functions to frontend code.
That leads to unsatisfied external references if the C compiler failsto elide unused static functions. Apparently, we have no buildfarmmembers building HEAD that have that issue ... but such compilers stillexist in the wild. Need to do something about that.In passing, fix Berkeley-era typo in comment.Discussion:https://postgr.es/m/27054.1558533367@sss.pgh.pa.us
