More cleanups. Stop using __ identifiers for internal stuff now that it's properly marked private and we don't have to worry about conflicts.

libobjc2: Add a pile of NULL checks. In general, any public function should be able to handle NULL for any object/class/selector/pointer to opaque structure without blowing up.

In some irritating circumstances, the load order can cause a +load message to trigger other code, which sends messages with selectors that have not been mapped yet.
...
The runtime was handling the message lookup correctly in this case, but only as a side-effect of the fallback code from when type-dependent dispatch is not possible. This resulted in a confusing warning message, telling you that you were calling a method with an incorrect signature, when the two signatures that it printed were the same.
This case is now handled correctly, so the warning disappears (unless you really are calling a method with the wrong signature and have TDD enabled).

Allowed hash tables to dynamically resize. This uses toydispatch to free the old version of the table after copying all of the data into the new one, after waiting enough time to allow all potential readers to finish. There are theoretical cases when this can fail, but hopefully no practical ones. The theoretical cases can be removed by making the garbage thread run at a lower priority than all of the other threads in the system.
...
The protocols table and the class table will now grow as required. Protocols are now added to the protocols table as they are created, so you should get something sensible and introspectable back when you look up a protocol by name.

Added hopscotch table implementation and rewrote the class table to use it. This is done so that the class table and protocol tables can share the same code (currently there is no protocol table).
...
Note that concurrent resizing has not yet been implemented. That means that there is a hard limit on the number of classes that can be loaded. This is currently set to quite a small number for testing, to stress the hash table. If you're experiencing problems as a result, then please let me know and I will increase it.
