/proc/interrupts can have such a structure ...
98: 35 0 2902361 PCI-MSI-X eth1-0
106: 61 11 3841 PCI-MSI-X eth1-1
114: 28 0 61452 PCI-MSI-X eth1-2
122: 24 1586 22 PCI-MSI-X eth1-3
130: 2912 0 337 PCI-MSI-X eth1-4
138: 21 0 28 PCI-MSI-X eth1-5
146: 21 0 56 PCI-MSI-X eth1-6
154: 34 1 1 PCI-MSI-X eth1-7
... and will not count all IRQs for eth1-*. Thus change it to
sum up multiple entries.

Just a minor change to also show the total number of cpus in the
headline.

It's not used anywhere anymore, so remove it.

The refresh interval can only be positive and is stored in an uint64_t,
so use strtoul() to convert it.

When parsing irq numbers on e.g. 24 CPU machines, procfs lines can get
very long, so our static temporary buffer size will fail here with:
Assertion `!(stats->irq_nr == 0)' failed.
So allocate it relative to the CPU number.

I've tested it on a 24 CPU machine, and it does not look so nice if
there's different padding along the lines. This patch fixes it.

There are people with machines containing far more than 32 CPUs. In
their case ifpps didn't work until now because of a limitation to 32
CPUs.
Rework ifpps to support an arbitrary number of CPUs. In order to still
remain within the display space, if more than 10 (TOP_CPUS) CPUs are
available, only the 10 top hitting (in terms of usr and sys time or irqs
respectively) are displayed.

Add the __noreturn attribute to all functions which wont return
but call die() themselves to exit().

Replace "on default" by "by default", make it a bit more clear what the
seed in the -E/--seed option is for and mention exit after display of
information on --version and --help.

We do not assign or use this particular state, so just remove it from
the enum. We continue anyway in the while loop in that case.

Remove various unreachable sections from the switch statements. This

We decided to get rid of the old Git history and start a new one for
several reasons:
*) Allow / enforce only high-quality commits (which was not the case
for many commits in the history), have a policy that is more close
to the one from the Linux kernel. With high quality commits, we
mean code that is logically split into commits and commit messages
that are signed-off and have a proper subject and message body.
We do not allow automatic Github merges anymore, since they are
total bullshit. However, we will either cherry-pick your patches
or pull them manually.
*) The old archive was about ~27MB for no particular good reason.
This basically derived from the bad decision that also some PDF
files where stored there. From this moment onwards, no binary
objects are allowed to be stored in this repository anymore.
The old archive is not wiped away from the Internet. You will still
be able to find it, e.g. on git.cryptoism.org etc.
