[lttng-dev] [PATCH lttng-tools 2/4] Tests: Add helper functions for printing status and test banner

[Christian Babeux]

Add three new printing functions:

print_ok: Print the OK status with optional color support.
print_fail: Print the FAIL status with optional color support.
print_test_banner: Print a test banner of the test description.

e.g.:
   	   sometest.sh:
	   TEST_DESC="A really useful test"
   	   [...]
	   source $TESTDIR/utils.sh
	   print_test_banner
	   [...]
	   print_ok
	   print_fail
	   [...]

	   $ ./sometest.sh
	   ----------------------
	    A really useful test
	   ----------------------
	   OK
	   FAIL
