3c233ca4ea Fix Windows environment issues 
Summary:
Enable directIO on WritableFileImpl::Append
     with offset being current length of the file.
     Enable UniqueID tests on Windows, disable others but
     leeting them to compile. Unique tests are valuable to
     detect failures on different filesystems and upcoming
     ReFS.
     Clear output in WinEnv Getchildren.This is different from
     previous strategy, do not touch output on failure.
     Make sure DBTest.OpenWhenOpen works with windows error message

26adaad438 Split WinEnv into separate classes. (#1128) 
For ease of reuse and customization as a library
  without wrapping.
  WinEnvThreads is a class for replacement.
  WintEnvIO is a class for reuse and behavior override.
  Added private virtual functions for custom override
  of fallocate pread for io classes.
