Scott Graham 10165ce449 Cross platform low level file IO wrappers
Rename fd_io to file_io, and ReadFD to ReadFile, etc.

file_io.cc is the higher level versions that call the basic ReadFile/WriteFile
and then file_io_posix.cc and file_io_win.cc are the implementations of
those functions.

The Windows path is as yet untested, lacking the ability to link the test binary.
