[PATCH 0/4] trace: introduce trace event injection

[Cong Wang]

This patchset introduces trace event injection, the first 3 patches
are some trivial prerequisites, the last one implements the trace
event injection. Please check each patch for details.

I have tested them with both valid and invalid input on different
tracepoints, it works as expected.
