uri -> phos_uri for !HAVE_ASR_RUN

switch to phos_uri Initially I took the IRI parser from gmid, stripped of the UTF-8 things and transformed back into a URI parser. Then I've added some functions to resolve URIs, but it wasn't enough. gmid parser is aimed at servers, and so it doesn't handle very well relative links. This makes use of the libphos uri parser, which was coded to follow the RFC more strictly, and to fully support all kinds of URIs. It'll need to be expanded in the future and be improved for sure

fix continue condition

handle success code other than 20 20 is the only used, but *technically* one (read: Sean and his client torture test) can send 29, 27, ...

correctly handle the port in the request add an explicit port if one is given and it's not 1965

fmt

simplify host resolution on !HAVE_ASR_RUN no functional changes intended

request buf: 1024 is the limit for the URL
