Make the read built-in more compatible with bash:
- Return an exit code of 142 on timeout.
- When the timeout expires before a newline is detected in the
input bash captures the partial input. This behaviour is new
since bash version 4.4. BusyBox shells had the pre-4.4 behaviour
where the input was lost.
Update the tests to suit and fix a couple of compiler errors in
the testsuite.
