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]
