1fe107875b Overhaul network I/O to be async for real 
Had to totally cut off OpenSSL from the network fd because obviously
OpenSSL is just going to wreck our shit

a22bec5149 add a missing "/" to autoindex paths 
With the following directory structure:

/srv/gmni:
baz/  foo/

/srv/gmni/baz:
a

/srv/gmni/foo:
bar/

/srv/gmni/foo/bar:
b

trying to access gemini://somesite/ with autoindex=on works,
but accessing /foo fails because it tries to stat /srv/gmni/foobar
instead of /srv/gmni/foo/bar. This commit fixes that by adding a trailing slash.

e77f354ca3 serve: fix gcc-9.3.0 error in serve_autoindex 
gcc 9.3.0 catches an off-by-one error with strncat in serve_autoindex
where it might not write a 0 byte:

  In function ‘strncat’,
      inlined from ‘serve_autoindex’ at src/serve.c:60:3:
  /nix/store/...glibc-2.31-dev/include/bits/string_fortified.h:136:10:
  error: ‘__builtin___strncat_chk’ specified bound 4097 equals destination size

9d17ce46b0 return false on request_validate errors 
This will report proper errors to clients rather than continuing on with
request processing.

7fed84898b Only handle one client per poll iteration 
This is a bit of a hack but it avoids some problems with invalid reads
when a client gets disconnected

7af04ea471 tls: move cert/key into host structure 
We'll later want to set these on the SSL object (rather than SSL_CTX),
so move these into the host struct for later access.

We'll prefer to set it on the SSL object so that we can automatically
use an up-to-date certificate, per ~sircmpwn/gmni#26.
