commit 9b374f41eee2db5080ef2feb7973228afa3b22aa
from: Omar Polo <op@omarpolo.com>
date: Sun Jan 10 14:40:14 2021 UTC

macro reordering

and while there replace SAFE_SETENV with an inline function.  LOG is
more difficult to transform into an inline function, given the string
concatenations it does.  The other LOG* and FATAL macros are fine as
they already are.
