evil: Rename EAPI macro to EVIL_API in Evil library
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.

so evas cpu used to be the thing then eina cpu came and did the same
and evas cpu optionalyl could lsit on top... just move it all to eina
cpu so one central place does this and evas_cpu is purely a compat
wrapper.
Summary:
the previous patch which improved this code for x86 archs broke compiling
for non-x86 and, coincidentally, for windows builds on x86 due to some
unusual #ifdef blocks
this attempts to restore handling on non-x86 and adds additional #ifdefs for
functions which did not build on windows due to removed code

Summary:
To determine if a system supports SIMD instructions, the cpuid facility
should be used. However, for 15+ years EFL has been trapping SIGILL,
then attempting to execute these intstructions.
Continuing after SIGILL is explicitly undefined behaviour and can never
safely be relied upon - it is possible the CPU will respond to the
unknown instruction in an upredictable way and the program will not
continue correctly. Even if it hasn't caused problems before, there's
no reason to believe a processor released in the future won't behave
differently.
Lately we've had a couple of bug tickets where SIGILL appears to cause
problems at a system level as well, but there seems little point in
chasing those problems down as we shouldn't even be doing this in the
first place.
ref T6711
ref T6989
We still rely on SIGILL in a few configurations where eina_cpu doesn't
know how to query features properly (powerpc, sparc, and non linux
ARM configurations). Hopefully someone with expertise on those
platforms can follow up and we can remove this entirely.
Note: MMX2 appears to not really be a thing, and is instead provided by
both 3DNow! and SSE. We already conflate it with SSE in other parts of
evas, so I've just used SSE here to test for its presence.
Depends on D6313

Summary:
Add new define, BUILD_NEON_INTRINSICS to control whether NEON inline code or
NEON intrinsics should be built.
GCC NEON intrinsics can be built both for armv7 and armv8. However NEON inline
code can be built only for armv7.

Evas_Common.h should be used for the public header, and rather rename
evas_common.h internal header to another name.
Sa:
Evas_Common_Header.h -> Evas_Common.h
evas_common.h -> evas_common_private.h
Shouldn't have both Evas_Common.h and evas_common.h because of case
insensitive filesystems.
I've tested make -j 3 install and it works nicely
I've tested expedite with software and opengl xlib,
and it works. Not tested other engines, so please
report any problems (engines or other) on the ML.
TODO: examples and tests, I'll add them later
ISSUE: Eina_Unicode size check. It indirectly depends on
eina_config.h, which is created at the end of the
configure script. So its size is always 0. I don't
know how that size is used, so I can't do a lot,
for now.
