[PATCH v5 0/3] Add array printing helper to ftrace

[Javi Merino <javi.merino@arm.com>]

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

Changes since v4[0]:
  - Specify the element size in __print_array() as bytes instead of
    bits

Changes since v3:
  - 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
