UC-1185 Investigate log entry "received response without transaction"

Lowered the log level from WARNING to INFO. This message is logged for
every response passing the UA for which a live transaction could not be found.
We chose to keep it on INFO level and not lower it to  DEBUG level
because this log is a way of measuring the proxy's effort of forwarding
responses with no transaction. However on some scenarios it should be expected
because proxy's NatMaintainer does keep alive by sending an OPTION request with
no transaction, so, for every OPTION message send by NatMaintainer this
log message will be logged.
UC-1472 Proxy should forward statelessly multiple 2xx responses to INVITE requests

The stacklib's UserAgent class was updated to send statelessly any 200 OK
responses to INVITE requests. Any other responses will just be ignored.
XX-10758 Proxy high cpu utilization when disabling Bria's TLS account

Sometimes, when reading EOF from socket, proxy was entering in a loop
sending empty keep-alives messages to itself. To fix this proxy should
check for keep alives only if EOF was not read.

XX-10788:  dn_expand requires the second argument to point to the end of the msg pointer.  However the old implementation simply hard codes it as msg+512 which can overrun the buffer.  This results to unknown behavior for dn_expand which sometimes returns -1 for a perfectly formatted msg.
