tracker: Fix the map look up
...
A few commits ago, an attempt to speed the map look up was done.
Unfortunatly, it was missing the case where you actually hit the speed
up (once the map is the first element of the array, you never return
it).
So, make sure that if i is 0, you return the first element of array,
while still doing the array reordering is i > 0.

Speed up map locating in tracker.c
...
Store the maps as a GArray rather than a GPtrArray to improve
locality; also move maps to front when they are looked up.

Make comm events reuse any existing process.

A comm event doesn't necessarily mean a new process was created. It
may just mean that an existing process changed its command line.

Skip symbols from IRQ stack.
...
There is a bug in the kernel where it includes the stack of the IRQ
that generated the event, so that the stack ends up looking like this:
[ip] [irq stack] [real stack].
As a temporary workaround, this patch filters out the irq stack
symbols.

Show the "-- kernel --" marker in kernel threads
...
The innermost context is normally user mode, so we don't show. For
kernel threads, the innermost context is the kernel, so don't filter
it out.
