Felipe Magno de Almeida 1304d95717 eldbus: Rename EAPI macro to ELDBUS_API in Eldbus library
Summary:
=  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.

Felipe Magno de Almeida 835b8756ec Fixes ABI breakage in Eldbus for use with C++ Eldbus
Summary:
This fixes the breakage when Eldbus_Service_Interface_Desc added a
wrongfully methods2 field to a class that is allocated by the user.

This patch adds the respective eldbus_service_interface_register2 and
eldbus_service_interface_fallback_register2 for registration of
Eldbus_Service_Interface_Desc2 which is now versioned. So future the
functions can be backwards compatible and the struct be forward
compatible and leaves the Eldbus_Service_Interface_Desc and
eldbus_service_interface_register and
eldbus_service_interface_fallback_register intact as it was in EFL
1.10.

This fixes T1408

Felipe Magno de Almeida 1baf9e4825 eldbus: Fixes ABI break in Eldbus_Method with appended void* data
Summary:
Removed the void* data variable from Eldbus_Method and created another
struct that has the void* data and added an array of Eldbus_Method2 in
the descriptor for the Eldbus_Service_Interface_Desc and making the
appropriate modifications in the implementation to use both
descriptions.

Felipe Magno de Almeida 30df128be5 eldbus-cxx: Implementation of eldbus C++ API
Summary:
Applications can:

  void method_callback(void* data, const Eldbus_Service_Interface* iface,
                       const Eldbus_Message* message);
  struct { ... } data_struct;

  Eldbus_Method methods[] =
   {
     "method1", ELDBUS_ARGS("b", "bool"), ELDBUS_ARGS("b", "bool"), ELDBUS_METHOD_FLAG_HAS_DATA
     , (Eldbus_Method_Cb)&method_callback, &data_struct
   };

   And method_callback will be called with data parameter pointing to data_struct global object.

Also, Eldbus-cxx supports registering an interface passing a lambda or
function object as method. For example:

  edb::service_interface iface = edb::service_interface_register
    (c, path, interface
     , es::method("SendStringAndBool"
                  , [expected_string, expected_bool] (std::string const& n, bool b
                                                      , bool* out)
                  {
                    std::cout << "Running SendStringAndBool" << std::endl;
                    ck_assert(n == expected_string);
                    ck_assert(b == expected_bool);
                    *out = b;
                    return n;
                  }
                  , es::ins<std::string, bool>("string", "bool")
                  , es::outs<std::string, bool>("string", "bool")
                  )
    );

When a request for "SendStringAndBool" with the proper signature is
called, executes the lambda and replies with the return value and
its bool* out parameter value.
