trace: add generic tracepoints

Browse Source 
This patch creates the following generic tracepoint for
generic tracing when there is no dedicated tracepoint is
available.

- rte_eal_trace_generic_void()
- rte_eal_trace_generic_u64()
- rte_eal_trace_generic_u32()
- rte_eal_trace_generic_u16()
- rte_eal_trace_generic_u8()
- rte_eal_trace_generic_i64()
- rte_eal_trace_generic_i32()
- rte_eal_trace_generic_i16()
- rte_eal_trace_generic_i8()
- rte_eal_trace_generic_int()
- rte_eal_trace_generic_long()
- rte_eal_trace_generic_float()
- rte_eal_trace_generic_double()
- rte_eal_trace_generic_ptr()
- rte_eal_trace_generic_str()

For example, if an application wishes to emit an int datatype,
it can call rte_eal_trace_generic_int(val) to emit the trace.
