normalize schema when parsing the IRI RFC3986 in section 3.1 "Scheme" says that > Although schemes are case-insensitive, the canonical form is > lowercase and documents that specify schemes must do so with > lowercase letters. An implementation should accept uppercase > letters as equivalent to lowercase in scheme names (e.g., allow > "HTTP" as well as "http") for the sake of robustness but should only > produce lowercase scheme names for consistency. so we cope with that. The other possibility would have been to use strcasecmp instead of strcmp when checking on the protocol, but since the "case" version, although popular, is not part of any standard AFAIK I prefer downcasing while parsing and be done with it.

track handshakes This alter the current state machine by adding S_HANDSHAKE as the initial state. There, we ensure we did the handshake and we check SNI. ATM we simply continue in S_OPEN, but later we can add virtual host checks there, and skip to S_INITIALIZING with an error state if the client is accessing a wrong host.

avoid __dead and return at the end of main

fix build on non-OpenBSD systems not every system has a __dead attribute for functions. This fixes the build on FreeBSD.

reject non-gemini protocols with 53

remove infinite loop

s/uri/iri since we accept IRIs

fix build

new README + wording in manpage

fix remote_user for CGI and add -6 flag to enable ipv6

accept both ipv4 and ipv6

log also the port of the client

make FATAL and LOG inline functions other functions that aren't macros anymore. LOG went under a rename to logs because log is a builtin (the math function), or so gcc says.

inline should be before type, gcc says clang doesn't seem to care.

macro reordering and while there replace SAFE_SETENV with an inline function. LOG is more difficult to transform into an inline function, given the string concatenations it does. The other LOG* and FATAL macros are fine as they already are.
