CVE-2019-16235, CVE-2019-16236, CVE-2019-16237

[Julian Andres Klode]

A triplet of security issues.

[Julian Andres Klode (juliank)]

Compiled in autopkgtest, installed into lxd container, and tested with the test case for bug 1866115 - which this also includes.

The goal is to build in security, push to proposed to SRU verification, and then push to -security, as we need to get the IV acceptance change out fairly quickly so later dino versions can switch to sending 12-byte IVs w/o breaking compat with bionic users.

Afterwards I'll try to SRU dino 0.1.0 stable release as that includes a ton more (mostly) fixes.

I have installed dino-im from the PPA and tested:

- Group chat

- Verification for bug #1866115

Everything seems to work fine.
