Address Andrew's comments
- use TEST_VALUE macro instead of open coded value
- use WIFx macros for child status testing
- kill child/parent on error
Note that it was not clear from an initiall patch
change log -- the difference between fifo_wronly
test case and this one is that we use fork() call
here which allow us to make sure that fifo restoration
code logic will be tested more widely.
Basically the flowchart of the test case:
parent child
------ -----
open RW fifo (slave)
open RO fifo (master)
open WO fifo (master)
dup parent slave to slave1
... waiting c/r to happen ...
... waking up from c/r ...
send bytes to master
send bytes to slave1
finish
... initiating c/r ...
... waking up from c/r ...
read bytes from master
read bytes from slave
PASS :D

Sometime we need sync points in testee program flow,
for this reason task_waiter_ introduced.
The call semantics is the following
Parent Child
------ -----
task_waiter_init
task_waiter_wait4
task_waiter_complete
task_waiter_wait4
task_waiter_complete
...
Thus initially task_waiter_init should be called
to initialize all internals guts needed.
Then one become waitee and calls for task_waiter_wait4,
where lockid should be provided as an argument. Since
it should be unique values the best option might be
gettid().
The same applies to a waiter side -- it should call
for task_waiter_complete and provide a lockid.
