Andrew Kryczka 59b3ee658f Env function for bulk metadata retrieval
Summary:
Added this new function, which returns filename, size, and modified
timestamp for each file in the provided directory. The default implementation
retrieves the metadata sequentially using existing functions. In the next diff
I'll make HdfsEnv override this function to use libhdfs's bulk get function.

This won't work on windows due to the path separator.

Test Plan:
new unit test

  $ ./env_test --gtest_filter=EnvPosixTest.ConsistentChildrenMetadata

README

This directory contains interfaces and implementations that isolate the
rest of the package from platform details.

Code in the rest of the package includes "port.h" from this directory.
"port.h" in turn includes a platform specific "port_<platform>.h" file
that provides the platform specific implementation.

See port_posix.h for an example of what must be provided in a platform
specific header file.
