SYNOPSIS
int logon(void)
DESCRIPTION
When the parser accepts a new connection, it first calls
connect() in the master object and then applies logon() to
the object that is returned by the master. That will usually be
a special login object, that is expected to clone and get going
a user shell or user object.
Should return 0 on failure, everything else means success.
