Subject: Tests: use babeltrace2 for all tests
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=c125de8f5c0dc9ba3ada63e9317e468ffb9e335a;p=lttng-tools.git

Tests: use babeltrace2 for all tests

- Change value of `BABELTRACE_BIN` to `babeltrace2`,
- Replace all direct calls to babeltrace with calls to `BABELTRACE_BIN`
  variable,
- Add `bail_out_if_no_babeltrace` bash function to fail the test if
  Babeltrace 2 is needed but not found.
