net.http.parser: Improve handling of responses without content-length This ensures that we support responses without a content-length header, and allow streaming them through the streaming handler interface. An example of such a response would be Server-Sent Events streams.

sessionmanager: Improve logging around session destruction

core.sessionmanager: Mark session as destroyed to prevent reentry If it reaches this point, then the session will be most definitely be destroyed, so try to prevent destroy_session() from being called again.

core.sessionmanager: Skip log when (not) destroying destroyed sessions On regular disconnects, </stream> is sent, then sessionmanager.destroy_session() is called, then sessionmanager.destroy_session() is called again when the TCP connection is closed, from ondisconnect in mod_c2s. It is a bit annoying and doesn't really tell you much.

util.crypto: Preemptively silence 'strict-prototypes' warning With `gcc-12 -Wstrict-prototypes` the following warning is shown: crypto.c:43:13: warning: function declaration isn't a prototype [-Wstrict-prototypes] 43 | static BIO* new_memory_BIO() { | ^~~~~~~~~~~~~~

mod_storage_sql: Remove module status on unknown 'debug' level Expected this to be translated to 'core', but it logs an error instead. See previous commit.
