Since fdinfo patches were merged to -mm
tree the output format has been slightly
changed. So update our tool accordingly.

A value of signo is in [1, SIGMAX].
Currenly signals are enumirated from 1 to SIGMAX, but SIGMAX
is not included. This patch fixes this mestake.
v2: * save backward compatibility
* set a correct value of SIGMAX = 64. It can not be in a
separate patch, because a format is changed again.

Switching to a new stage is 4-step procedure which
deserves its own helper. Besides, now the information
about how many tasks participage in each stage is
collected in one place.

When finishing a stage we have to report this (decrement the
number of tasks in stage) and wait while stage switch. Write
a helper that does both.

If you have an error in parasite.c and execute make from vim,
without this patch vim opens a new file parasite.c in a root directory.
With this patch vim opens pie/parasite.c.

The SO_BINDTODEVICE getter is changed in the kernel (before
official release) to report not index, but name to be in
harmony with setter.
Fix crtools accordingly.

Otherwise test with -d option get fail (this is because
SIGTRAP get cleared by our parasizte engine).
The proper fix most likely will require kernel patching
or redesign of parasite code. Meanwhile to make test
working we switch to the signal which just known to work.

If we have tree threads, a following situation can occur:
T2: dec task_entries->nr_in_progress
T3: dec task_entries->nr_in_progress
T3: futex(&task_entries->nr_in_progress, WAKE_UP);
T1: unmap task_entries
T2: futex(&task_entries->nr_in_progress, WAKE_UP) -> EFAULT -> BUG_ON()
This patch adds a futex for synchronising threads.
