Log Message:
bitlbee: Update to 3.6

Version 3.6:

- irc/core:
  * Add server-time IRCv3 capability (blastrock)
  * Add PROXY command for haproxy/stunnel
  * Large performance improvements for large contact lists
  * Many UX/documentation improvements
  * Added built-in crash handler that writes to /var/lib/bitlbee/crash.log
  * Try to join long spaceless lines in paste_buffer without a newline. The
    main use case for this is pasting long URLs and not breaking them
  * Fix status message being set to null accidentally
  * Fix handling utf8 nick renames when loading configs (MaskRay)
  * Fix SSL's SNI with hostnames starting with a digit (CMB)
  * Show correct nick when `rename -del` is used (arcnmx)

- twitter:
  * Disable the stream setting by default. Filter streams still work.
  * Update default character limit to 280 chars (qyliss)
  * Fix quote tweet url display.

- jabber:
  * Try to join anyway after "Already present in chat"
  * Fix chat joins when ext_jid is provided for your own user.
    Seen with Biboumi (a gateway from XMPP to IRC)
  * Handle always_use_nicks more gracefully to reduce nick change noise

- otr:
  * Don't block attempts to connect/smp/smpq to "offline" users

- Removed dead protocols:
  * msn: Use the skypeweb purple plugin instead.
  * skype (the dbus based thing): ditto.
  * yahoo: It's so dead even the replacement protocol died.
  * oscar: AIM is dead, for ICQ use the icyque purple plugin instead.

- For plugin devs:
  * Add datadir to pkgconfig file and config.h (sm00th)
  * Add "bitlbee-set-account-password" purple signal (for hangouts)
  * Support libpurple 2.12.0's PURPLE_MESSAGE_REMOTE_SEND for groupchat
    self-messages (for slack)

- Packaging/distro specific stuff:
  * bitlbee@.service now sends stderr to syslog instead of the socket
  * debian: only enable bitlbee.service, not bitlbee.socket too
  * cygwin: portability fixes for plugins
  * Support OpenSSL 1.1 built without backwards compat (cotequeiroz)
