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.

i saw a segv on freeing em->msg as it was a junk ptr... i dont know
for sure it msg was properly initted but as em is recycled from trash
be sure and zero it when digging out of trash because em->msg was not
a valid ptr (and i wasnt using valgrind at the time to know for sure
and cant find this with valgrind now).
@fix
613e1715be (and friends) added a bit a
biug where messages in the queue were not skipped as they were before
causing a segv witha null lookup. this fixes that. eclipse about
dialog showed this bug up. no longer happens now.
more optimizations for edje messages to avoid excess alloc and frees
if we have some trash around... since messages already have list
nodes, re-use the main list node for storing trash and not eina trash
as this avoids extra allocs for trash nodes.
so to process a single obj we added a lot of mesgs to the message
queueue only then to wak most and SKIP most msgs again and again -
when this adds up to 1000's of messages and 10k+ then literally moving
a window in e hangs for multiple seconds and we walk such lists in On2
like complexity. this gets it down to O(1) along with some other minor
optimizations of not adding to tmp list only then to add them to the
nex queue/list.
there is more i can optimize here as well now we track messages for an
edje in th edje. that's next.
using regular lists means we double our indirect ptr jumps and
fragment ram more - this is step one in improving performance of
message handling in some nasty corner cases i have found. first this
so it can be identified as an issue on its own if it is one. i've
tested it and it seems ok. so this si stage 1.
Original patch by Jinwoo Shin:
If edje has multiple levels of child group,
edje_object_message_signal_process cannot process message on
child group. To cover that, it needs to add new API which
traverses its hierarchy and process messages.

Since this uses generic_value (aka Eina_Value), there is an
implicit type detection and conversion. I did not attempt to
cover all types (namely string+int and string+float and even
less sets of those) as I believe they aren't really used. Or
they most likely could be replaced by multiple messages rather
than a single message.
Note: should we pass ptr(generic_value) instead of generic_value?
The API looks a little odd in C when passing by value.
@feature
It is used to receive messages with a payload from embryo to C.
This API has a function pointer, which means it would have to be
manually bound, or transformed (eg. eo event).
Also, prepare the change for message_send to use Eina_Value and
no explicit type.
This feature seems rarely used.
But note that handler_set is in fact used in terminology, rage and
luncher. So, if the need arises, it will have to be transformed in
a proper EO way.
thjis was deprecated even before efl 1.0 by never removed. lua
replaced it for script_only objects and you havent been able to
compile an edje file with script_only enabled since 1.0, so no point
having the code here.
this cleans up that code and cruft.
this is still in progress, mostly the multisense stuff is pending.
it seems that when we merge ecore_audio in edje the libremix and
similar are gone, at least from Edje, and will be in ecore_audio
itself (or pulseaudio).
Changes:
* __UNUSED__ to EINA_UNUSED
* binaries (epp, embryo_cc, edje_cc) now consider EFL_RUN_IN_TREE and
will assume the binaries are still not installed, running from
build tree location (needs more testing, maybe doesn't work with
srcdir != builddir, still doesn't solve cross compile builds)
