The documentation for PJSIP_HEADERS claims that
prefix is optional, but in the code it is actually not. However, there is no inherent reason for this, as users may want to retrieve all header names, not just those beginning with a certain prefix.
This makes the prefix optional for this function,
simply fetching all header names if not specified. As a result, the documentation is now correct.
Resolves: #230
UserNote: The prefix argument to PJSIP_HEADERS is now optional. If not specified, all header names will be returned.
