Initial fixes for ticket #747: bugs in parsing SIP torture messages (RFC 4475):

 - SIP version components may be separated by whitespaces (e.g. "SIP / 2.0")
 - parsing of mangled header when for unknown/generic header
 - Via parameters were parsed with paramchar rather than token
 - handling NULL character inside quoted string

Some torture messages have been added in the Python test.
