begins with $, but is not $SYS, then an assert that should be unreachable is
triggered and Mosquitto will exit.

Fixes CVE-2017-7651: Unauthenticated clients can send a crafted CONNECT
packet which causes large amounts of memory use in the broker. If multiple
clients do this, an out of memory situation can occur and the system may
become unresponsive or the broker will be killed by the operating system.
The fix addresses the problem by limiting the permissible size for CONNECT
packet, and by adding a memory_limit configuration option that allows the
broker to self limit the amount of memory it uses.
The hash of new tarball is not (yet) available through download.php, so use
a locally calculated hash.

Drop CVE 2017-9868 patch as that is now upstream.
1.4.14 is a bugfix release, fixing significant websocket performance /
correctness issues.
Use HTTPS for the download as the server uses HSTS, thus saving a redirect.
While we're at it, add hashes for the license files.

Commit e51d69a3b (mosquitto: specify that hash is taken from upstream)
changed the .hash description header, but the upstream hash only applies
to the tarball, not the patch.

Fixes CVE-2017-9868: In Mosquitto through 1.4.12, mosquitto.db (aka the
persistence file) is world readable, which allows local users to obtain
sensitive MQTT topic information.

Fixes CVE-2017-7650: Pattern based ACLs can be bypassed by clients that set
their username/client id to ‘#’ or ‘+’. This allows locally or remotely
connected clients to access MQTT topics that they do have the rights to.
The same issue may be present in third party authentication/access control
plugins for Mosquitto.

- This version requires a patch (sent upstream) to remove -lanl from
all Linux builds as this library is only needed for adns support
- sha512 must be computed locally as eclipse.org does not give it for
this version

This includes a fix for a security related bug related to the listener
mount_point feature. The bug allows a client that is restricted to a
mount_point to publish messages outside this hierarchy using the last will
and testament feature.

'echo -n' is not a POSIX construct (no flag support), we shoud use
'printf', especially in init script.
This patch was generated by the following command line:
git grep -l 'echo -n' -- `git ls-files | grep -v 'patch'` | xargs sed -i 's/echo -n/printf/'
