These are deprecated and will be killed in short time, stop using them!
Recommendations:
* ecore-txt: use eina_str_convert, drop in replacement, just sed.
* ecore-config: convert your code to use eet + Eet_Data_Descriptors
directly, it is simpler and faster, but requires you to change your
code. Consider using eet_data_descriptor_file_new() and
eet_eina_file_data_descriptor_class_set() or
EET_EINA_FILE_DATA_DESCRIPTOR_CLASS_SET(). Then describe your type
with EET_DATA_DESCRIPTOR_ADD_*().

this will have compilers to completely compile out log statements
using levels greater than the given number.
this is defined in config.h, thus C files should include this before
including Eina.h, as should be the case for all files (IOW: if it does
not work for some file, that file already have a bug).

If an fd_handler created a recursive main loop (just called
ecore_main_loop_begin()), then this recursive main loop should
continue to process fd_handlers from there and on, thus
fd_handler_current (and win32_handler_current) was added. When going
back from recursion, the current iterator should be updated properly.
This patch also fixes the deletion of fd_handler from recursive main
loops by reference counting them. This way, the node will not be
free()d inside inner loop cleanups and then crash when going back to
outer loop.
PS: win32 code is untested (or even compiled).

Add reference counting to events, event filters and event handlers so
they can recurse main loops.
Note that the required "continuation" when entering main loops is not
there, thus recursion will restart and this will fail badly in lots of
cases. This should be fixed in future commits.

recursive main loops.
Unlike idlers, timers seems to work reasonably well with main loops, I
*think* they might fail since it used a boolean to flag running as
opposed to a reference count with incremental increments/decrements. I
could not write a test case to demonstrate so.
The now code should be simpler, particularly the
_ecore_timer_call(). It will also consider the previous position when
entering recursive main loops, preserving the order.
Deletion of timers are delegated to ecore_main.c, that was already
calling _ecore_timer_cleanup() after timers were executed.

If an idle_exiter created a recursive main loop (just called
ecore_main_loop_begin()), then this recursive main loop should
continue to process idle_exiters from there and on, thus
idle_exiter_current was added. When going back from recursion, the
current iterator should be updated properly.
This patch also fixes the deletion of idle_exiters from recursive
main loops by reference counting them. This way, the node will not be
