Felipe Magno de Almeida 4cee5b05c9 evil: Rename EAPI macro to EVIL_API in Evil library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.

EAPI was designed to be able to pass
```__attribute__ ((visibility ("default")))``` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.

MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.

For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.

With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
```

Example 1:
dll1:
```
EAPI void foo(void);

EAPI void bar()
{
  foo();
}
```
dll2:
```
EAPI void foo()
{
  printf ("foo\n");
}
```

This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
```__atttribute__((visibility("default")))```

However, the following:
Example 2:

dll1:

```
EAPI extern int foo;
EAPI void foobar(void);

EAPI void bar()
{
  foo = 5;
  foobar();
}
```

dll2:

```
EAPI int foo = 0;
EAPI void foobar()
{
  printf ("foo %d\n", foo);
}
```

This will work on mingw but will not work for MSVC. And that's why
EAPI is the only solution that worked for MSVC.

Vincent Torri 01b987df59 make mman.h private
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

Vincent Torri 7782e2388c Evil: fix infinite recursive loop in previous addition of setlocale() in Evil
Summary:
setlocale() called itself because it was defined as a #define
so remove this #define from evil_locale.h and move it in another header file
To avoid future problem, move similar defines to this header file
Also clean all the header file mess in Evil
