efl: stupid micro optimization. 

This single test accounted for 1% of my terminology benchmark.
I am considering moving evas_string_char_next_get and
eina_unicode_utf8_get_next to become inline as their function
entry/exit point account for 3% of the same benchmark.

The biggest win would be to get rid of the memcpy _termpty_text_copy
that account for 16%.

In the micro optimization part, we also still do to much malloc
in font_draw_prepare as we don't recycle the array there and account
for 3% of the benchmark in malloc/free there. In the same ballpark
_text_save_top account for 2% of the time in malloc/free.

In that same benchmark, evas_object_textgrid_render account for 5%
where 4% of its time is spend in evas_common_font_draw_prepare. At this
point I am not sure that rewriting textgrid is gona help us at all. We
will win almost as much by just inlining the get_next things in evas
and eina for a minute of development time.
