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:
with autotools, EFL_BUILD was passed to the preprocessor for libraries and binaries, which was wrong. Only libraries must have EFL_BUILD defined. See T7797 for an explanation
This also fix EAPI in Ecore_Getopt.g and Efl_UI.h
Also note that all the wayland and drm Makefile's have not been touched

Summary: There are some typos and calogique statements in doxygen
of Ecore_Getopt and Ecore_Legacy so I had fixed typos and cacologique statements.

Some parts of the API documentation where not compiled at all by doxygen
because of missing '@{' and '@}' tags. This commit adds the missing tags
in Ecore_Getopt.h, Ecore_Con_Eet.h, and Ecore_IMF.h headers.
positional arguments must appear at the end of the description array
(after the last option) and should have a metavar set and not have
shortname or longname. Simple, elegant and fit :-)
There is a new function to parse the positional arguments,
ecore_getopt_parse_positional() because we may want to not try to
parse them in the case of a quit-option such as --help, --license,
--copyright, --version or some user-defined action. This avoids us
producing errors of missing positional arguments when printing help
and adds some flexibility as well.
This should make Tasn happy :-)
do not include Ecore_Input.h just to get Ecore_Window and Ecore_Getopt
to get handful typedefs.
NOTE: why do we have the #ifdefs around these predefs? At least GCC does not warn if we typedef twice the same thing (if they are identical)

Thanks to PrinceAMD (Deon Thomas) for bugging me to implement this,
then test and add a fix, now we can implement something similar to
"xterm -e" in terminology.
ECORE_GETOPT_ACTION_BREAK will allow generic options to behave the
same as GNU's --, breaking out of argument parsing logic.
