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

Currently, vector and image support svg format via different rountine.
Our vector loader implemenst on its own drawing mechanism for svg,
but in case of image loader, it depends on rsvg library.
By Comparing both, our vector svg is winner at performance wise.
we can remove rsvg routine later.
For now, these two loader names are conflicted, we should separate their names
with svg and rsvg.
