* Fix Will message for a persistent client incorrectly being sent when the client reconnects after a clean disconnect.
* Fix Will message for a persistent client not being sent on disconnect.
* Fix mosquitto_pub not using the `-c` option.
Thanks to Yannic Schröder.
Closes#1273.
In order to connect to brokers that support both websockets and
mqtt on the same port (such as Amazon IoT), we need to set an
application for the SSL context. This change allows the specification
of an application by using the `bridge_alpn` configuration token.

This includes changes to improve read/write performance.
It is not complete, and will have further changes to add properties and anything else required for MQTT v5.
Some OpenSSL engines (selectable via tls_engine option) may require a
password to make use of private keys created with them in the first place.
The TPM engine for example, will require a password to access the underlying
TPM's Storage Root Key (SRK), which is the root key of a hierarchy of keys
associated with a TPM; it is generated within a TPM and is a non-migratable
key. Each owned TPM contains a SRK, generated by the TPM at the request
of the Owner. [1]
By default, the engine will prompt the user to introduce the SRK password
before any private keys created with the engine can be used. This could
be inconvenient when running on an unattended system.
Here's where the new tls_engine_kpass_sha option comes in handy. The user
can specify a SHA1 hash of its engine private key password via command
line or config file and it will be passed on to the engine directly.
This commit adds support for both clients (libmosquitto) and broker.

- Clients can now offload crypto tasks to an external crypto device through
the OpenSSL ENGINE API.
- The keyfiles can now be treated as PEM or ENGINE keys.
- Two new functions were added to libmosquitto to set up the previously
mentioned features.
- Both mosquitto_sub and mosquitto_pub include support to turn on the mentioned
features through command line options.

This comes in the form of:
* Per listener maximum_qos option, which can be in the range 0-2.
* Changes to mosquitto_publish*() to return MOSQ_ERR_QOS_NOT_SUPPORTED
if attempting to publish with a higher QoS than supported.
* Bridges will downgrade messages to match the maximum QoS.
More tests on the broker side (specifically bridges) are required. This
needs bridge support for MQTT 5 first.
The connection wouldn't always complete if mosquitto_loop_start() was
called before mosquitto_connect_async(). Closes#848.
Thanks to Ian Gough.
