Added PWM module for PicoC. Now, the PWM modules
for both Lua and PicoC coexist.
Added CAN module for PicoC. Now, the CAN modules
for both Lua and PicoC coexist.
Added another parameter in can_recv function.
The eLua function 'can.recv' returns 3 values -
canid, length and message. However, in PicoC,
the function returns length. 'data' is sent
via a reference.
