 	use Eina_Spinlock in Eina_Log, replace Eina_Lock by Eina_Spinlock in Eina_Stringshare,
 	Eina_Chained_Mempool.
 	* Eet: replace Eina_Lock by Eina_Spinlock in Eet_Dictionnary.

      - Add neon assembly for upscaling and map routines
      - Use mmap/munmap for image data allocation on system that have mmap.
      - Add iterator for walking child of smart objects, table and a box.
+     - Use Eina_Spinlock for Evas_ScaleCache, Evas_Async_Events and Image_Entry.
     * Ecore_Con:
      - Rebase dns.c against upstream
      - URL support now dynamically loads libcurl at runtime via eina_module.
