/*
IQUEUEs
 
This file contains functions that helps to manage task queues.
 
These functions are different from the functions that manages the
QUEUE and QQUEUE types. In particular, these functions no more relies
on the prev & next fields of the task descriptor. In that way, tasks
can be inserted in more than one queue at a time.
 
Basically, an IQUEUE has an "I"nternal prev/next structure, that may
be shared between one or more queue. Of course, the user MUST
guarantee that the same task will not be inserted in two IQUEUEs that
share the same prev/next buffer.
 
The queue insertion is made by the following functions:
iq_insert -> insertion based on the priority field.
