timers_unix: Fix termination problem of WaitReceiveTaskEnd

The function pthread_kill sends the Signal thread and to the own process.
If you use this construct than the application which calls uses the
canfestival api will terminate at the call of canClose. To avoid that
use pthread_cancel instead of pthread_kill. To use the pthread_cancel call
you need to set the cancel ability in the thread function. That means
you need to call pthread_setcancelstate and pthread_setcanceltype.
For the termination of the thread at any time it is important to set the
cancel type to PTHREAD_CANCEL_ASYNCHRONOUS. 
Kvaser driver for CANfestival, the open source CANopen stack.
(C)2008 Giuseppe Massimo Bertani 


This driver should work with any Kvaser product compatible with Kvaser's CANLIB4.
I tested it with CAN Leaf Professional (USB-CAN adapter) on a Suse10.1 Linux box
and CANLIB 4.72 Beta (Oct 1,2007). 

In order to compile the driver, you should already be able to run the CANlib examples,
and tools, to be sure that CANLIB is able to detect and drive your device.

NOTES ABOUT CANLIB4

Since the "Leaf" device was added recently to CANLIB, I had to download the latest linuxcan4
library sources from http://www.kvaser.com instead of use the CD software shipped with the device.

--------------------------------------------------------------------------------------------------
NOTES ABOUT WINDOWS

Sadly, Kvaser's Win32 CANLIB is not provided with sources, so CANLIB cannot be build with GNU
tools. LIB files for MSVC and BCC are provided with the DLL but the DLL itself is stripped and
I've tried an entire day to compile this driver under Cygwin without success, despite 
Wu Yongwei's hints (http://www.geocities.com/yongweiwu/dllfaq.htm).

This does not mean that it's an impossible task, but probably I left out something important. 
Temporary KO.
