core.certmanager: Move EECDH ciphers before EDH in default cipherstring (fixes #1513) Backport of 94e341dee51c The original intent of having kEDH before kEECDH was that if a `dhparam` file was specified, this would be interpreted as a preference by the admin for old and well-tested Diffie-Hellman key agreement over newer elliptic curve ones. Otherwise the faster elliptic curve ciphersuites would be preferred. This didn't really work as intended since this affects the ClientHello on outgoing s2s connections, leading to some servers using poorly configured kEDH. With Debian shipping OpenSSL settings that enforce a higher security level, this caused interoperability problems with servers that use DH params smaller than 2048 bits. E.g. jabber.org at the time of this writing has 1024 bit DH params. MattJ says > Curves have won, and OpenSSL is less weird about them now

util.prosodyctl: Tell prosody do daemonize via command line flag (fixes #1514) Backport of 88be11e9f9b9

net.http.server: Use error code from util.error (fixes #1502) Oversight in 955e54e451dc when this was added.

mod_scansion_record: Indent stanzas in recordings Improves readability, easier to see structure.

util.stanza: Add method returning stanza with added indentation Adds indentation and line breaks to stanzas, to make stanzas easier to read for humans.

mod_component: Specify an error source for Component unavailable errors It is somewhat ambiguous where an error really comes from in the case of an external component. Setting by to the bare host at least distinguishes it from JIDs with a node- or resourcepart.

spec: Include a hacky moduleapi stub to allow test to proceed

MUC: Switch hats to new presence APIs

MUC: Add API for adding 'filtered namespaces' to be stripped from inbound presence
