Commit 6fdbce12 attempted to sort the list of tests, but failed
(without quotes, echo merges all the tests into a single line,
so there was nothing to sort).
* tests/schematestutils.sh: Fix thinko in previous patch.
Having a test that depends on file system timestamps and/or inode
allocation order gives non-deterministic output.
* tests/schematestutils.sh: Run test in deterministic order.
* tests/test-lib.sh: "echo -n" is not portable. Use printf instead.
Remove unnecessary uses of "eval-in-subshell" (subshell is sufficient).
Remove uses of tests' -a operator; it is not portable.
Instead, use "test cond && test cond2".
* tests/schematestutils.sh: Replace use of test's -a.
Only print out '.' for each test case, full test output can be
re-enabled with VIR_TEST_VERBOSE=1, or VIR_TEST_DEBUG=XXXX
Sample output now looks like
TEST: statstest
........................................ 40
................................... 75 OK
PASS: statstest
TEST: qparamtest
................................ 32 OK
PASS: qparamtest
TEST:
............ 12 OK
