Fix tracecontext seek backward underflow
Fix a problem with the detailed event list "seek backward". In the following
condition:
- Long interval between events (e.g. generated with power management suspend).
- Happening close to trace start.
- Trace start near 0s 0ns.
The substraction could underflow. Fix this by comparing the time to substract
and floor to trace start time if it would underflow.
The visible effect was that the detailed event list is seeked to the end of the
trace rather than the previous event when going "up" one event prior to the
suspend begin.

Text mode clock synchronization
Adds linear regression based clock correction of a group of traces. This is
mostly a reimplementation of the work presented in
[1] Clément, E.: Synchronisation de traces dans un réseau distribué, École
Polytechnique de montréal, 2006
This implementation does not use a synchronization "window" and timeouts as
described in figure 3.3 of [1]. Not using that algorithm, we don't have to
rely on the system time to be loosely synchronized; events can be processed
regardless of the order the traces are merge-sorted. The downside is that
there is no limit to the number of events that could be queued up, waiting for
their matching event from another trace. The solution to this would be to
insert extra logic (like a plugable module) that controls the merge-sort;
upstream of event delivery to the syncrhonization code. Many possibilities
come to mind:
1) reimplement something like what is found in [1] that relies on system time
for a weak pre-synchronization
2) use a heuristic based on the size of the current queue for each trace in
the synchronization code. If a trace's queue is growing and growing, deliver
events to other traces.
This implementation also does not need to keep track of the IP adresses
assigned to local interfaces. If a packet is processed by the network
subsystem it can be used for synchronization. There is no need to know if the
node really the packet's final destination.

Temporary fix for large IRQ tables
IRQ tables, trap tables and softirq tables can grow. The copy mechanism for

We should change the g_new allocations for g_arrays, and use the array length as

wakeup wait for cpu display
Here's a slightly more constructive patch: this one adds support in
LTTV's generic state monitoring code and its control flow visualiser to
note when a process is woken by another process using the
sched_try_wakeup event.
Previously the woken process would continue to register its old state
until such time as it got scheduled; here the process transitions to
WAIT_CPU state (like preempted processes, indicating it is ready to run
but not currently scheduled). Ordinarily we see this state exist very
briefly, in between the device driver IRQ (typically) clearing it to run
and the scheduler invocation after irq_exit, but on a heavily loaded
system we might see a large stripe of dark yellow indicating the process
is ready but cannot yet be allocated a core.
The new code in controlflow/eventhooks.c is essentially a copy of the
second half of before_schedchange -- it would be nice to factor these
two and before_execmode, all of which basically identify a process,
create state objects if necessary, and draw his line up to a certain
time.
