API docs describe keepalive incorrectly

[ElmerLastdrager]

In the API docs, the description of the keepalive value is wrong. It currently states:

keepalive the number of seconds after which the broker should send a PING message to the client if no other messages have been exchanged in that time.

This should read:

keepalive the number of seconds after which the client should send a PING message to the broker if no other messages have been exchanged in that time.

Relevant lines:

mosquitto/lib/mosquitto.h

Line 337 in 46630e7

* keepalive - the number of seconds after which the broker should send a PING

Agreed - keepalive is needed by client - if no messages prior to the keepalive time, ping should be sent by the client.
