[PATCH v4 0/3] Add array printing helpers to ftrace

[Javi Merino]

This series add a helper to the tracing framework to trace arrays.
Patch 1 adds them and patches 2 and 3 update the traceevent library to
parse them.  They've been tested with trace-cmd.

Changes since v3[0]:
  - use %zu to print size_t

Changes since v2:
  - Changed BUG() into a trace_seq_printf()
  - Add BUILD_BUG_ON() to chase mistakes in element sizes on build
  - Add patch 2 to avoid repeating code in patch 3.
  - print a warning in traeevent if the size of the array is not valid
