time and timeouts have no consistent type in OSAL

[ghost]

In OSAL, time and timeouts are represented typically by both int32 or uint32. This convention is used in many places. It might make sense to have a consistent type for time. Perhaps even absolute and relative time. There are Wconversion issues with uses of these types.

[skliper]

Looks like some timeouts handle OS_PEND (-1). although inconsistent use of int32/uint32.

Example code snips:

	/** @brief OSAL time */
	typedef struct
	{
	uint32 seconds;
	uint32 microsecs;
	} OS_time_t;
