Adding a new method

From reSIProcate

A method not known to the parser will have type resip::UNKNOWN. You can get to the string with, for example:

if (msg->header(h_RequestLine).getMethod() == UNKNOWN)
{
   const Data& methodName = msg->header(h_RequestLine).unknownMethodName();
   ...
}

To add a built in header:
You must have gperf.

1. MethodTypes.hxx: add defineMethod(name, "name", "RFC ref"),
   before MAX_METHODS
2. MethodTypes.cxx: add defineMethod(name, "name", "RFC ref"),
   to MethodNames[] initializer in the same position
3. Methodhash.gperf: add name, name
   on its own line before the last %%
4. compile and run stack/test/testParserCategories
