move defaults.c prototypes in defaults.h

sort vars

use iri_setport instead of reaching into the struct iri

iri: add iri_setport() takes a string because the internals of telescope makes it easier to use if a string.

remove phos; now unused phos was an attempt at building a gemini client/server library. It didn't went as I expected, mostly because it's such a simple protocol... Anyway, the only use in telescope was for the uri module, which has already been replaced with the built-in iri. Which still sucks (and despite the name, can still only handle URIs) but it's hopefully better. The APIs are better.

convert the remainig uses of phos_uri to the iri API

net: don't need a uri, just host and port fields While here, make 'em dinamically allocated.

move cwd to fs.c

update copyright date for emoji.txt

apply load-url-use-heuristic for command line arguments too This semplifies a bit the handling. humanify_url() now takes the base URL which we can then use when not using the heuristics. Command-line arguments now take an implicit base of <file://$PWD/> when the heuristics are disabled, so that foo.gmi resolves to the local file even without <./>. See github issue #10.

iritest: one more test, just in case It stemmed from my misuse of iri_parse(). There's nothing wrong in the parser (that I found at least), but one more test won't harm.

convert humanify_url to iri APIs

convert ir_select_reply() to iri

add missing include

fix iritest CFLAGS; add iritest to TESTS
