timers_unix.c : remove sigint and sigterm catch
sdo : Allow multiple servers
The sdo transfer struct is not anymore referenced by server's node id but by
client or server number in the OD. Node id is not relevant in SDO transfert.

fixed bug with cross wmingw build

Removed unneccessary overhead introduced with the last fix.

Fixed incorrect struct access in sendPDO() and inserted a missing variable in sendOnePDOEvent(). These errors occured at compile-time when configuring the project with './configure --debug=PDO' or './configure --debug=WAR'.

Fix some side effects of EDS import, while editing afterward

FIXED: - changed make targets from "%o: %c" to "%.o: %.c" (Patch from irc <oleg_osov>)
find . -name 'Make*' | xargs perl -w -i.bak -p -e "s/\%o: \%c/%.o: %.c/g"

FIX: - if a sdo transfer timeout occurres, reset the sdo line even if the callback function does not.

FIXED: - Sdo lines with the internal state SDO_ABORTED_ITERNAL are now closed.

CHANGED: - canSend message parameter is now a const pointer
ADDED : - IXXAT specific can bus watchdog to restart the VCI2 driver if a bus off, data ovverrun or remote queue overrun is detected. The can adapter cannot recover on its own.
