bugfix: the default for $DirCreateMode was 0644, and as such wrong.
It has now been changed to 0700. For some background, please see

This one did not surface yet and the issue was actually found due to
a problem in v4 - but better fix it here, too.

Thanks to William Tisater for analyzing this bug and providing a patch.
The actual code change is heavily based on William's patch.

Thanks to Frederico Nunez for providing the fix. The actual patch
was commited before this one - unfortunately I forgot to set
the author correct when commiting it and then it was pushed to
the online repository. Sorry for this ;)

- a big one in syslogd.c, which caused messages not to be
  freed when compiled for single-threading mode
- a small one in the file output handler, outchannels, when
  a size-reached action was to be executed

this caused a very minor issue with re-formatting a RFC3164 date when the
message was invalidly formatted and had a colon immediately after the date.
This was in the code for some years (even v1 had it) and I think it never
had any effect at all in practice. Though, it should be fixed - but definitely
nothing to worry about.

New syntax @[addr]:port introduced to enable that. Root problem was IPv6
addresses contain colons. (backport from 3.21.3)
