tr_req_handler: Handle non-defaulted case

In 1.4, we broke forwarding requests that were not defaulted.  We
looked up the community as a member of the community rather than the
realm.  Fix this logic error.

Also, update error messages to be more accurate and to fibx a spelling error.
tr_config: remove free calls

Since we're using talloc, we only need to free the entire
configuration and that will cascade to sub objects.  Remove calls to
free, which are wrong anyway for talloc'd memory.
Set busy timeout

Set a busy timeout in the tids sqlite3 setup code so that we do not
fail on any database locking.  As an example in 1.4 if two tids
processes try to write at the same time, one will fail.
Mark version 1.4.1
