Vinnie Falco 2b69831f49 New constructors for message:
The message class now behaves like a pair with respect to the construction
of the body and headers. Additional constructors allow construction of
just the body portion from a tuple, leaving the headers default
constructed.

Previous constructors are removed as they were a notational convenience
for assembling HTTP/1 requests and responses. They are not necessary
as this library aims at library writers and not end users.
