* eet: fix bad allocation case triggered by edje new file format. 

Bad news, I also discovered in the same time that we introduced an
	API/ABI breakage in 1.3.0. This patch does prevent it from coming
	again, sadly, it imply an ABI break that I didn't find a proper
	way to work around. So recompile eet and all the program that use
	it after that commit.

* Add EET_DATA_DESCRIPTOR_ADD_HASH_STRING.
2010-08-06 Cedric BAIL
* Break eet_eina_* function helper to provide a clean API/ABI to
prevent futur break. This should prevent the ABI break that was
introduced with release 1.3.0.
* Add a specific allocator for array. This should fix wrong allocation
case discovered with recent edje file format change.
