0 is still used for 2X replies, and "external" failures (e.g.
network, tls, ...) are still using exit code 1. Gemini non-2x
replies now get their response code reported as-is as status code.
Somehow the compat for __dead is not working properly on macos
(cirrus ci) since it complains that parse_debug() does not return
a value in all control paths when it uses usage() (marked as __dead)
to catch a wrong usage.
various servers are not handling correctly the close notify so for
the moment don't turn this into an hard error but just warn.
Hopefully, given some time, most servers will be fixed.
while here, drop the gotos and just use a break to exit the main
loop.
This is a better version of gg. Initially it grew with flags directly
needed to the specific test cases I wanted to write, so it's ugly to use
but handy for tests.
This is a new and re-thought implementation that it is (hopefully)
easier to use both and "curl-like for gemini" but also for scripts and
tests cases.
One completely new feature is the proxying support with -P to send the
request to the given host.
Include gmid.h as first header in every file, as it then includes
config.h (that defines _GNU_SOURCE for instance).
Fix also a warning about unsigned vs signed const char pointers in
openssl.
* add -H for explicit servname (for SNI)
* add -v to print also the request
* misc tweaks: move *flag variables to global scope (initialisation to
0 for free!) and explicit handshake.
