the new synch library

Hello all,

I have just committed the first working version of the synch library.

I have not yet implemented the mapping between the simpler config file syntax and the complete petri net specification syntax. That will come
next.

Have a look at the linuxplc.conf file in /lib/util to get an idea of how to configure the petri net.

I have updated the plctest program to allow testing the synch library.
We now have two new options:
plctest -w <synchpt_name> --> will wait
on the specified synchpt.
plctest -l --PLCmodule=<module_name> --> will run an infinite
loop calling plc_loop_beg() and plc_loop_end()

The plc_loop_xxx() functions will synchronize with the synch points specified by the name=value pairs "loopbeg" and "loopend" under the
<module_name> section. If this is left unspecified then it will synch with the null synchpt that always returns without any delays.

Sorry, don't have any more time to explain further. Maybe tomorrow.


Mario.
