Summary:
integrate mman.h to make Evil private to the EFL, as mman.h does not exist on Windows. After a discussion with raster, i include sys/mman.h only on non Windows platform.
One issue, though, is that src/modules/emotion/generic/Emotion_Generic_Plugin.h has inlined functions using mmap()
Test Plan: compilation on Windows
