Summary:
Benchmark executables do not need to export and import symbols because
they are not loaded by other executables. Removing is important because
EAPI will be removed in some later commit and would break benchmark
executables.
= The Rationale =
This patch is 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
LIBAPI is the only solution that works for MSVC.

Get your seatbelt fastend! It is happening! AUTOTOOLS IS GONE NOW!
All praise to meson!
This time the final version, ci has been adjusted, and now does not try
anymore to build a removed buildsystem. However, the scripts in there
need cleaning up.

Some user code may want to track an object ownership in regard to whether it is
kept by just one owner or shared between many owners.
This is specially true for code provided by bindings to other programming
languages, where different kinds of resource management may take place.
The event `ownership,unique` is triggered whenever the object refcount goes
from two to one, as a signal that it has just one owner from now on.
The event `ownership,shared` is triggered whenever the object refcount goes
from one to two, as a signal that it has multiple owners from now on.
It will not trigger when further increasing the refcount to any value beyond
two.
We also add benchmarks for sharing (i.e. increasing the refcount) and them
unsharing objects, in order to evaluate the performance impact of this patch.

As in the previous commit explained, we want to get rid of class
functions in eo, and make them just c functions right away.
This commit removes the class parameter from the eo_class_function_set
call, and adjusts the tests to not depend on class functions anymore.
Class functions are now not tested anymore, tests that used them as a
way to test *things* are adjusted to test them now with object
functions, tests that just tested the working of class functions are
dropped.
This fixes T7675.

a new shiny buildtool that currently completes in the total of ~ 4 min..

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.

This change lets us remove a field from the structure that leads to
around 20KiB more of saving in private dirty pages in elementary.
This also looks a bit better and feels a bit cleaner.
Breaks API and ABI.
Before this commit, function overrides were explicit. That is, you'd
have to explicitly state you were overriding a function instead of
creating a new one. This made the code a tad more complex, and was also
a bit more annoying to use. This commit removes this extra piece of
information.
This means we now store much less information per function, that will
let us further optimise out structures in the future.
Efl.Object.event_callback_call no longer calls legacy smart callbacks;
calling only event callbacks registered with the given event description
pointer.
Create the method Efl.Object.event_callback_legacy_call to inherit the old
behavior from Efl.Object.event_callback_call, calling both Efl.Object events
and legacy smart callbacks.
Update all other files accordingly in order to still supply legacy
callbacks while they are necessary.
This was never used and there is no plan to ever use it. I'm going to
soon add a different mechanism with which it will be possible to provide
them again to Eo if ever needed without breaking ABI. Though it's
unlikely it will ever be.

I just ran my script (email to follow) to migrate all of the EFL
automatically. This commit is *only* the automatic conversion, so it can
be easily reverted and re-run.
This reverts commit 1714fe93f4.
We actually want this type, it makes things clearer.

Tests are disabled by default, but they should be mandatory for
distcheck. So should be examples, we should have them to at least
compile.
As there is no way to force "make distcheck" to run "make examples",
I've created --enable-always-build-examples to make examples regular
noinst_PROGRAMS, being always compiled. distcheck will use that
option.

- remove EFL_LIBS and EFL_CFLAGS, use per-lib values that inherit
from EFL (general)
- add NAME_LDFLAGS and EFL_LDFLAGS for linker flags.
- LDADD (binaries) now use NAME_LDFLAGS instead of NAME_LIBS, as they
link to libname.la and that will pull in the libtool dependencies
