Eo: pointers indirection mechanism for objects and classes Summary: This feature replaces Eo pointers with ids to prevent bad usage or reuse of these pointers. It doesn't change API. The mechanism uses tables storing the real pointers to the objects. See the src/lib/eo/eo_ptr_indirection.c file for more details on the mechanism.

eo: a little more inlining, give me a 10% speed improvement.

eo ptr ind: speed up by caching last used table - keep a reference to the last used table and it's indexes - use this table prior to normal search through table arrays

/* Current table used for following allocations */

eo ptr ind: empty tables are freed except 1 kept as spare - this reduces unused memory usage - the spare table avoids the free/alloc corner case

/* Next generation to use when assigning a new entry to a Eo pointer */
eo ptr ind: set generation counter range to [1;max-1] - so we never generate an Eo Id equal to 0, thus don't need to skip the first top table index anymore

Generation_Counter _eo_generation_counter = 0;
Eo: Add internal function call on pointer errors Useful for GDB: break on this function when things go wrong. Similar to eina_safety. I guess we could set some Eina_Error and maybe even have error callbacks for easier application debugging. Later.
