IndexedDB: Support auto-increment keys

Let's cache the last autonumber.  It's even OK if we leak some numbers as long as it always increases.

Also, I believe that the expected behavior is that if you have a keypath and autoIncrement value, the latter should get inserted into the former...even if it already exists.  I don't remember in detail and maybe this should be brought up on list and/or changed.  Also, such behavior can be punted to a later patch if non-trivial...but we should catch the error and raise an exception if so.

Done.

You're right, I was reading an old version of the spec. And injecting the auto incremented value into an object is non-trivial, so I'm punting on that.

Re-writing the big if-else block at the start of IDBObjectStoreBackendImpl::putInternal to hopefully make it a bit clearer.

"Not yet supported"?
