lib/tst_test.c: Run test in child process
This commit moves the actuall test to a child process. The parent process now
serves two purposes. It sets up an alarm timer that kills the test on a timeout
and also does the library setup and cleanup which means that the test temporary
directory is removed even if the test crashed in one of the functions exported
in tst_test structure.
The timeout is defined per test run, which is either one execution of
test_all() function or single loop over the test() function. The timeout is
reset after each test run by the test library by sending SIGUSR1 to the parent.
The default timeout is set to 300 seconds and can be overriden by setting
tst_test->timeout variable.
There is also LTP_TIMEOUT_MUL env variable that, if set to float > 1, is used
to multiply the timeout before the start of a test. This is especially intended
for slow machines where the default timeout may not be enough.
