* make AVAHI_VALID_FLAGS a global macro
* add new flag AVAHI_PUBLISH_NO_REVERSE, if set address records will no be created with matching reverse lookup PTR RRs
* add new flag AVAHI_PUBLISH_NO_COOKIE, for not implicitly adding the service cookie to TXT records
* minor cleanups

Yes, this will break the mono bindings. More breakages to come.

NO_REVERSE and NO_COOKIE needs testing.

Lathiat, I guess the new flag NO_REVERSE makes the immediate need to add a client side API to add arbitrary RRs obsolete for now. You might consider moving it in the TODO list to "later".
