Don't use decode_packet/3 for parsing the request-line

First step in making all methods and header names binaries to
get rid of many inconsistencies caused by decode_packet/3.

Methods are all binary now. Note that since they are case
sensitive, the usual methods become <<"GET">>, <<"POST">> and so on.
