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.

switch some macros to inline functions they expanded multiple times their argument, since inline is standard (and works on GCC 4 too!) why don't use it?

switch to Bjoern Hoehrmann UTF-8 decoder It's correct, while my hacked valid_multibyte_utf8 would allow things that aren't technically UTF8.

remove leftovers from debugging

simplify loop todo was initially there for an optimization: don't loop to MAX_USERS when you know the upper limit is todo.

simplify unveil/pledge calls

rename cgi_setpoll_on_* to cgi_poll_on_*

initialize error string to avoid returning garbage

fixing prototype order

ignore also SIGHUP SIGHUP is sent when the tty is detached and by default kills the process. When we run in the background we don't care anymore about the tty, so it should be safe for us to ignore SIGHUP. (frankly, I expected daemon(3) to do stuff like this for us).

fix CGI with new IRI parser With new IRI, parser the old assumption of path starting with ./ is no longer valid.
