```

Also remove operator bool in Error. The Error should be removed
later because it is not necessary for Paddle. We are now using Enforce
to handle error.

Use CHECK instead of PCHECK, because PCHECK is used for errno.

The implementation of BarrierStat is buggy, and it is not necessary
for Paddle to diagnose which node in cluster is slow.

Fix #2567

__must_check is a macro mark of function return value. It let developer
must check the return value is legal or not.
