sanjay 7e12c00ecf Fix issue 474: a race between the f*_unlocked() STDIO calls in env_posix.cc and concurrent application calls to fflush(NULL). The fix is to avoid using stdio in env_posix.cc but add our own buffering where we need it. Added a test to reproduce the bug. Added a test for Env reads/writes. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=170738066		pirms 7 gadiem
