tracing: Add helpers to create trace remote events
Declaring remote events can be cumbersome let's add a set of macros to
simplify developers life. The declaration of a remote event is very
similar to kernel's events:
REMOTE_EVENT(name, id,
RE_STRUCT(
re_field(u64 foo)
),
RE_PRINTK("foo=%llu", __entry->foo)
)
