In certain cases 'leg_method' might be null so the IF statement:
if (leg_method && method_name && !su_casematch(method_name, leg_method))
continue;
is not working at all despite 'method_name' is not null. It leads to
leg matching process returns false positive at:
if (loose_match == NULL)
loose_match = leg;
…2.2; 17.2.3/ Implements missing matching rules (17.2.3.1 and 17.2.3.2)

This pull request consists of two commits and is aimed to avoid unexpected (wrong) "482 Request Merged" responses. These commits are implementing missing matching rules described in RFC3261 sections 17.2.3.1/2, and also fixing leg matching condition.
Use case: Call group calling process hunts sequentially for a group member that answers a group call. During a process it sends next INVITE upon previous one got canceled due to "No answer" or "Busy here" response. Such a next INVITE has different branch parameter in the topmost Via, however FreeSwitch (mod_sofia) still qualifies this new transaction as to be merged with an existing one. So the affords to add simple implementation of 17.2.3.1/2 rules and correcting the leg matching condition fixed the case.
