3efac7b7fa mqtt_msg: Set zero length username if password is set without username 
Some cloud server (e.g. exosite) takes empty username with password.

When password is set without username, the current esp-mqtt implementation will
ignore the username and only set password. This violates MQTT-3.1.2-22 [1].
To address this issue, send zero length username if password is set without username.

[1] MQTT-3.1.2-22: If the User Name Flag is set to 0 then the Password Flag MUST be set to 0.

8bb4a26f46 Config: Add a new option to use incremental message id 
This option is off by default, so the client still uses
random message id unless CONFIG_MQTT_MSG_ID_INCREMENTAL is set

b9db8d9020 Use size_t for all lengths 
Previously, uint32_t and size_t were used interchangeably. These types are
interchangeable on Xtensa gcc (uint32_t == size_t == unsigned int), but not on most
other 32-bit gcc architectures (where uint32_t == unsigned long, size_t ==
unsigned int).

ab1e8d7969 Support larger buffers and messages 
Use `uint32_t` instead of `uint16_t` for message and buffer lengths.
This is necessary for receiving messages that are larger than 65K.
