patch from Christian Taedcke <hacking@taedcke.com> : fix-wrong-resetSDOline-for-sdo-timeout.patch
FIXED: - The sdo line must not be closed at the end of SDOTimeoutAlarm() if the same sdo line is closed and reopened for a new transfer inside the callback. (Patch from Jaroslav Fojtik)

CHANGE: SDO block mode added, without CRC support
WARNING : API change in client functions

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.
