Add CO_..._initCallbackPre() for RPDO and SYNC (#178) 
* Merge two parts of CO_PDO_receive() into single common code

* Add CO_RPDO_initCallbackPre() for received RPDO messages

This optional mechanism allows to immediatelly wake the thread that
processes RPDO, without waiting for its next tick.

* Add CO_SYNC_initCallbackPre() for received SYNC messages

This optional mechanism allows to immediatelly wake the thread that
processes SYNC, without waiting for its next tick.

/**
* @defgroup CO_STACK_CONFIG Stack configuration
* @ingroup CO_driver
*
* Stack configuration macros specify, which parts of the stack will be enabled.
*
* Default values for stack configuration macros are set in CO_driver.h file.
* They can be overridden by CO_driver_target.h file. If specified so, they can
* further be overridden by CO_driver_custom.h file.
*
* Stack configuration macro is specified as bits, where each bit
* enables/disables some part of the configurable CANopenNode object. Flags are
* used for enabling or checking specific bit. Multiple flags can be ORed
* together.
*
* Configuration macros may be in relation with @ref CO_NO_OBJ macros from
* CANopen.h file. Former enables/disables stack functionalities, latter
* enables/disables objects in object dictionary. Note that some objects in
* object dictionary may need some configuration macros to be enabled.

/**
* Enable custom callback after CAN receive
*
* Flag enables optional callback functions, which are part of some CANopenNode
* objects. Callbacks can optionally be registered by application, which
* configures threads in operating system. Callbacks are called after something
* has been preprocessed by higher priority thread and must be further
* processed by lower priority thread. For example when CAN message is received
* and preprocessed, callback should wake up mainline processing function.
* See also @ref CO_process() function.
*
* If callback functions are used, they must be initialized separately, after
* the object initialization.
*
* This flag is common to multiple configuration macros.
