[MEDIUM] introduce the "timeout" keyword

A new "timeout" keyword replaces old "{con|cli|srv}timeout", and
provides the ability to independantly set the following timeouts :

  - client
  - tarpit
  - queue
  - connect
  - server
  - appsession

Additionally, the "clitimeout", "contimeout" and "srvtimeout" values
are supported but deprecated. No warning is emitted yet when they are
used since the option is very new.

Other timeouts should follow soon now.
