[LTP] [RFC PATCH 1/1] tst_test.sh: Print tst_{res, brk} into stdout

[Petr Vorel]

This allows printing messages on functions which output is redirected
into variable or used in eval. Also this change unifies the behavior
with C new API, which printed into stderr from the beginning.

Hope this change does not bring any regression.

Legacy API kept printing into stdout (legacy C API also prints to
stdout).

Hi,

some examples:

Before:
/opt/ltp/testcases/bin/tst_net.sh: line 885: 33mTCONF:: command not found
/opt/ltp/testcases/bin/tst_net.sh: eval: line 888: syntax error near unexpected token `('
/opt/ltp/testcases/bin/tst_net.sh: eval: line 888: `tst_rhost_run 1 TCONF: 'rsh' not found tst_rhost_run 1 TINFO: AppArmor enabled, this may affect test results tst_rhost_run 1 TINFO: it can be disabled with TST_DISABLE_APPARMOR=1 (requires super/root) tst_rhost_run 1 TINFO: loaded AppArmor profiles: none Summary: passed 0 failed 0 skipped 1 warnings 1'

With this patch:
tst_rhost_run 1 TCONF: 'rsh' not found
/opt/ltp/testcases/bin/tst_net.sh: line 885: Summary:: command not found
tst_rhost_run 1 TCONF: 'rsh' not found
/opt/ltp/testcases/bin/tst_net.sh: line 888: Summary:: command not found

tst_rhost_run 1 TCONF: 'rsh' not found
tst_rhost_run 1 TINFO: timeout per run is 0h 5m 0s
tst_rhost_run 1 TCONF: 'rsh' not found

Kind regards,
Petr
