Felipe Magno de Almeida a331384eed modules: Rename EAPI macro to MODAPI for modules
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.

=  The Rationale =

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 3ade45cbc8 Fix EAPI definition by defining EFL_BUILD for each built DLL
Summary: EAPI must be defined to dllexport when building DLL, and to dllimport when using these DLL. To achieve this, define EFL_BUILD for each library and module, and set DLL_EXPORT unconditionally. Static library are and will be not supported

Test Plan: compilation

Marcel Hollerbach 44a33c2dad meson: support unified suffixes for modules
A long story in a few words: sometimes on macos modules will be compiled
into .dylib, sometimes, into .so suffix. We did not set the suffix
everywhere in our meson build instructions, hence our suffixes have been
differently, which resulted in random load fails on different maschines.

With this commit, we ensure that we suffix all modules the same way.

Marcel Hollerbach 46d464e5bf here comes meson
a new shiny buildtool that currently completes in the total of ~ 4 min..
1 min. conf time
2:30 min. build time
Where autotools takes:
1:50 min. conf time
3:40 min. build time.

meson was taken because it went quite good for enlightenment, and is a traction gaining system that is also used by other mayor projects. Additionally, the DSL that is defined my meson makes the configuration of the builds a lot easier to read.

Further informations can be gathered from the README.meson

Right now, bindings & windows support are missing.

It is highly recommented to use meson 0.48 due to optimizations in meson
that reduced the time the meson call would need.

Jean-Philippe Andre 5d1e959f92 elm: Fix modules due to a missing EAPI
I recently added an undef EAPI which wasn't in fact the best idea ever.
The EAPI needs to remain defined as is for elementary modules and
edje_externals.

Amitesh Singh d88f08f7e9 eina: module - Add macros for adding module informations
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
 description:   Entry test
 license: GPLv2
