Fixes:
- fix some range check errors when compiling with all runtime checks enabled
- fix crash when server sends negative ConnAck packet (Reason <> 0), disconnect immediately instead.
- fix access violation when using FPC-3-2-fixes and making use of correlation data, it will crash when freeing elements of a dynamic array of records which themselves contain non-empty dynamic arrays of byte. Strings seem no problem. Seems fixed in trunk but crashes in fpc-3.2-fixes. Workaround is to store these byte sequences in strings instead.
API-Breaking
- correlation data is now a string and not an array of byte. Easier to handle anyways.
