7d84029 Flush/update CAPI handles better. Fixes #455. Previous to this, we were flushing all cached handles whenever a capi
function exited. We had a bug where we should have been updating all
capi handles when a capi function was entered. We now do 2 sets of
logic. The first is a faster, more simple logic of updating/flushing
handles seen by the current NativeFrame. This includes non-local handles
passed to R*(). This should deal with all reasonable extensions fine.

We also introduce -Xcapi.global_flush which when on will cause all
cached handles to be flushed/update on capi call boundaries.

b5f4157 C-API specs from kubo (#459). 
9a8f219 Temporary fix for perf regression in Array#include?. 
65c5e4d Replaced IdentityMap. Notes:

* Moved IdentityMap from Array to Rubinius.
* IdentityMap now supports re-mapping (#redistribute) when the entries
  exceed a certain threshhold. This happens automatically. The size is
  never reduced, however, because this is not a realistic need for the
  current use. Should this become necessary, it would be fairly simple
  to add to the #delete method as #redistribute could grow or shrink
  without any modification.
* The basic structure is a hybrid table of direct entries and rows mixed.
  On collision, the entry in the main table is promoted to a row and the
  colliding entry is added there.
* Deleting merely sets the entry for the item's hash value to nil. Under
  highly mutable loads (ie many inserts and deletes), this could lead to
  significant fragmentation. There are several ways this could be handled
  but, again, that is not in the current use cases.
* There is a slightly higher cost for small structures due to this being
  actually mutable rather than fixed. However, there is significantly
  greater performance as the load grows due to not having the spill array.
  Overall, this structure is much more robust.
