25aa50e0ca selftests: ftrace: Add a testcase for multiple actions on trigger 
Add a testcase for multiple actions with different
parameters on an event trigger, which has been fixed
by commit 192c283e93bd ("tracing: Add action comparisons
 when testing matching hist triggers").

ef39a01203 selftests: ftrace: Fix trigger extended error testcase 
Previous testcase redirects echo-out into /dev/null
using "&>" as below

echo "trigger-command" >> trigger &> /dev/null

But this means redirecting both stdout and stderr into
/dev/null because it is same as below

echo "trigger-command" >> trigger > /dev/null 2>&1

So ">> trigger" redirects stdout to trigger file, but
next "> /dev/null" redirects stdout to /dev/null again
and the last "2>/&1" redirects stderr to stdout (/dev/null)

This fixes it by "2> /dev/null". And also, since it
must fail, add "!" to echo command.

f06eec4d0f selftests: ftrace: Add inter-event hist triggers testcases 
This adds inter-event hist triggers testcases which covers following:
     - create/remove synthetic event
     - disable histogram for synthetic event
     - extended error support
     - field variable support
     - histogram variables
     - histogram trigger onmatch action
     - histogram trigger onmax action
     - histogram trigger onmatch-onmax action
     - simple expression support
     - combined histogram

    Here is the test result.
    === Ftrace unit tests ===
    [1] event trigger - test extended error support [PASS]
    [2] event trigger - test field variable support [PASS]
    [3] event trigger - test inter-event combined histogram trigger [PASS]
    [4] event trigger - test inter-event histogram trigger onmatch action   [PASS]
    [5] event trigger - test inter-event histogram trigger onmatch-onmax action     [PASS]
    [6] event trigger - test inter-event histogram trigger onmax action     [PASS]
    [7] event trigger - test synthetic event create remove  [PASS]
