Currently notification process called notably by message_{post,notify} does
not notify message's author by default. Rationale is that as he typed the
message he is already aware of it.
However in some cases we want to skip this step, notably when messages are
generated in the name of the author and when we want him to be notified if
he should.
This is currently controllable through a context key 'mail_notify_author'.
In this commit we add an explicit parameter propagated through the notify
process, allowing to remove some context key usage and instead use real
parameters.
Note that all context keys usage cannot be removed as it is not always
possible to propagate this parameter.
