more general message when slave can't start because of incorrect
replication information, the previous one was sometimes a misleading
indication (i.e. sometimes the problem had nothing to do with
system permissions).
The perfect fix would be to report the exact error to the client
(instead of pointing the client to the error log); this is a bit
of work so it's more a development task:
WL#1088 "Move all hardcoded messages of replication to share/errmsg.txt".
I was not able to modify the errmsg.txt in these sql/ subdirectories:

danish
dutch
german
italian
portuguese
russian
spanish
swedish
ukrainian
