UDPAddr leak

[cooltea713705]

First of all, thanks for your work!

We have noticed when using Server that there is a slow UDPAddr object leak (see pprof heap inuse_objects diagram below) over time.

Looking into the code, it seems raddr are being added but only get cleared when the server closes down as it's UDP.

We are still looking into if we are doing something wrong and what might be triggering those incoming UDP connections in our network.

Hi @cooltea713705 .
Thanks for using sipgo. Yes I think solving this problem was not the best, but we needed to track this addresses.
I will take some time to look into this.
