don't skip unit tests when SKIP_RUNTIME_TESTS is set
IRI and Punycode tests don't run gmid binary and can be safely executed.
prepare 1.8 release (tags/1.8)
allow using a custom hostname for SNI during proxying
add a `sni' option for the `proxy' block: the given name is used instead of the one extracted by the `relay-to' rule.
define TREE to shorten some url a bit
for the time being keep the https:// url, gmnigit renames file without extension to .txt (i.e. Dockerfile -> Dockerfile.txt) so linking via gemini is broken :/
only memcpy into imsg->data if datalen is not zero
Passing a NULL pointer to memcpy is UB no matter if len is 0 (commit by claudio@, backporting for gmid.)
