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:
These macros allow you to define module informations like
author/description/version/license
e.g.
// Use "Name <email id>" or just "Name"
EINA_MODULE_AUTHOR("Enlightenment Community");
// Mention license
EINA_MODULE_LICENSE("GPL v2");
// What your module does
EINA_MODULE_DESCRIPTION("This is what this module does");
// Module version
EINA_MODULE_VERSION("0.1");
Now eina_modinfo can show these informations to users
$ eina_modinfo module.so
version: 0.1

Summary:
I got an issue from emotion_basic_example, because my machine has following directories.
/usr/local/lib/emotion/modules/
├── gstreamer
│ ├── linux-gnu-i686-1.7.99
│ ├── linux-gnu-i686-1.8.0
│ └── linux-gnu-i686-1.8.99
└── gstreamer1
├── linux-gnu-i686-1.8.99
└── v-1.10
The defined MODULE_ARCH is v-1.10, and the _emotion_modules which is returned by eina_module_arch_list_get(); has two items.
Because eina_module_new(); creates Eina_Module, even though the "/usr/local/lib/emotion/modules/gstreamer/v-1.10/module.so"
does not exist.
Test Plan: Create directory without MODULE_ARCH, run emotion_basic_example, and check whether it works properly or not.
