Fix invalid config_file default value in main.cpp
Add setSize() method to databuffer class to shrink the size of the databuffer.
Add static serialize query and answer methods to packet class.
Simplified relay classes send queries and send answers methods.
Fix error in new setSize method. Will now properly allow increasing the
databuffer.
Add isSame method to record classes. It determines if the record is the same
as another record, in terms of the unique qualities. For example, if two
record's names do not match, they are not the same. But if the TTL of two
records do not match, they may still be the same.
Break out and simplify code to send queries and answers. Queries now will
include the known records (assuming it works). Additional records in answers
are not yet sent, need some work to figure out how to do that properly.
When doing a normal termination force-expire records are sent out for any
known answers.
Probably a few other things too.
