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.

Summary:
there is not any way to determine that this function has failed other
than to check this pointer, so ensure that it always has a value which
is meaningful in failure cases

Summary:
This fixes compilation on Windows
More precisely edje_cc could not compile emotion edc files, so it was a runtime problem
because of msvcr100 link.
Add more tests than before
Test Plan: compilation

This reverts commit bef1c5cc43.
The commit breaks the build on macos. I gave it soem time to get fixed
up quickly, but its late Friday night in Korea now and this is unlikely
to get fixed until Monday. Revert here until fixed.
./src/lib/eina/eina_private.h:158:1: error: unknown type name 'locale_t'

strtod's behavior is changed by system locale.
http://man7.org/linux/man-pages/man3/strtod.3.htmlhttps://en.wikipedia.org/wiki/Decimal_separator
Because of this, strtod(0.5) returns 0.0 in some locales.
When a given value string is locale-independent, strtod has to be
replaced to eina_convert_strtod_c function.
Internally, it calls strtod_l function with "C" locale.

The current implementation of eina_convert_itoa cannot convert INT_MIN.
When the input number is negative, the function negates it and this is
an undefined behavior for INT_MIN since -INT_MIN cannot be represented
in a signed int.
