cmumford c69d33b0ec Added native support for Windows. This change adds a native Windows port (port_windows.h) and a Windows Env (WindowsEnv). Note1: "small" is defined when including <Windows.h> so some parameters were renamed to avoid conflict. Note2: leveldb::Env defines the method: "DeleteFile" which is also a constant defined when including <Windows.h>. The solution was to ensure this macro is defined in env.h which forces the function, when compiled, to be either DeleteFileA or DeleteFileW when building for MBCS or UNICODE respectively. This resolves #519 on GitHub. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=236364778			pirms 5 gadiem

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