[reSIProcate] ParseBuffer::unsignedLongLong() bug

[Dmitry Semyonov]

Hello guys!

Please, change
   unsigned int num = 0;
to
   UInt64 int num = 0;
inside os/ParseBuffer.cxx: ParseBuffer::unsignedLongLong()

Some SDP fields are parsed incorrectly.

Also I think that unsigned long ParseBuffer::unsignedInteger() should 
be updated in similar way:
change 'unsigned int num' to 'unsigned long num'.
