Do not use pkfree_skb events for synchronization
Don't rely on events indicating when sk_buff structures are freed. After a
receive, we wait for another event indicating that this receive was for TCP
data. In the case where the data was not TCP, instead of keeping information
about the receive, we used to discard it when the skb was freed. It turns out
that it faster (and simpler) not to look at pkfree_skb events and keep the
information around anyways. Since sk_buff's are allocated in a pool, the
information will get overwritten and the size of pendingRecv will not grow

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
these is not correct when saving/restoring state, because it uses always the
name table size (which grows) to copy the saved/restored state snapshots.
We should change the g_new allocations for g_arrays, and use the array length as
boundary for the copy rather than the name table len.
TODO / FIXME !
I currently increased the initial irq name table size to 512 to deal correctly
with ARM. This is a dumb temporary fix.

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.

LTTV trace control bug fix
Chris Smowton <cs448@cam.ac.uk>:
...whenever I tried
to start a trace using the GUI, it would freeze consuming 100% CPU after
I clicked "start". Turned out this was because in tracecontrol.c's
start_clicked callback, you poll(2) on an FD and use a switch()
statement to handle its return.
Unfortunately, poll(2) doesn't work that way -- it returns a *mask* of
bits, not a single value. Here poll was returning POLLIN | POLLHUP to
indicate there's data ready and the FD has been closed by the other
side, and since this != POLLIN and != POLLHUP, the poll loop spins
forever.
Attached is a patch to be applied to tracecontrol.c which fixes it to
check for set-bits instead. It's still strictly broken, as the read(fd,
buf, 256) call might not fully drain the child's output, but it's a step
in the right direction and means I can at least use the trace-control
thing.

runlttv: Specify path of .runlttvrc
Use the path of the runlttv script to source .runlttvrc. This allows using
runlttv from a directory other than the one where .runlttvrc resides.

Do not initialize times before the frequency has been read
Do not calculate bogus begin and end values. Instead, skip that section of
code until the trace header has been read.

lttv: Change "dbg" option in runlttv
Change the "dbg" option to "gdb" for more homogeneity: `valgrind` and `strace`
are specified by the tool name, not by its function. This allows adding an
option for another debugger.

lttv: Extra arguments in runlttv
Here's an alternate take on specifying extra arguments for LTTV in the runlttv
script. They are specified on the command line after the optionnal "helper"
program name. This is more in line with the way commands like `xargs` take
extra arguments for the executable they invoke.
