Multiple backports from trunk:
    - rotatelog: Factor out from doRotate, main; make error handling consistant
                 and print the actual error to stderr
                 PR 45084
                 Backport of r1374247 from trunk.
    - rotatelog: Cleanups, no functional change.  Drop revision history,
                 "svn log" works; use APR_PATH_MAX; constify more
                 Backport of r1409800 from trunk.
    - rotatelog: error[120] is already defined in this function. Just use
                 it instead of shadowing.
                 Backport of r1416121 from trunk.
    - rotatelog: Use apr_snprintf(... "%pm"...) instead of explicit call
                 to apr_strerror
