Improve test framework

Browse Source 
The execute() and executeOk() functions now set $TFWEXECUTED instead
of $executed.

The execute() and executeOk() functions now make a hard link from the
--stdout-file=PATH and --stderr-file=PATH files to the default files
of 'stdout' and 'stderr' so that post-fork handling can still cat their
contents into the log file.

The fork() function now sets the variables $TFWFORKSTDOUT_<label>
$TFWFORKSTDERR_<label> $TFWFORKPID_<label>.
