This patch allows tracepoint to record a variable number of arugments. An additional function has been added, `spdk_trace_register_description_ext()`, which allows the user to register definitions for tracepoints specifying all the arugments that they accept. Users can also call `spdk_trace_register_description()` to register tpoints with a single argument (or none). Currently, all of the tracepoint arguments need to be passed as uint64_t. The trace record functions use variable arguments and rely on tracepoint description to know the order and the format of the arguments passed. That means that the user needs to take care that they're always in sync. Moreover, this patch extends the tracepoint entry size from 32B to 64B, meaning that there are 40B that can be utilized for passing arguments, which in turn means that there can be up to 5 arguments per tracepoint.
