4cd301bd92 Add pad unregistration
== DETAILS

I think this will fix the problem with duplicate pads--pads weren't properly
de-initializing and registering as disconnected. When a pad is disconnected,
the slot should properly release now.

97e09d179f Fix deadlocks when device is unplugged
== DETAILS
TIL that it's bad to call synchronization code from callbacks.

To avoid that, I made the following changes:

- Implemented an atomic swap (see previous commit) to avoid explicit
  locking when working with the event list
- ensure locks are only acquired in either the main thread or the
  I/O polling thread
- use an explicit polling loop; we still use async reads, but the
  read doesn't immediately re-invoke itself.
- remove the sleep in the polling thread.
- remove unnecessary locking in the thread cleanup call--verified that
  the list can't be modified while it is being executed.

== TESTING
I tested locally, and was able to disconnect/reconnect USB devices several times without the worker thread getting deadlocked.

af08e5015a More work on Dual Shock 3 driver
== DETAILS

- update to not try starting the read loop until after the device
  is successfully initialized
- add new HID wrapper macros needed by ds3 driver
- add some debug logging to help with troubleshooting
- add button map for DS3

== TESTING
Tested with local build. DS3 init is not working.

9bc5a15c2d Enable pads to register in any order
== DETAILS

Whereas the last commit had a hack (that disabled the wiimote
driver in the process), this has.. well, a *different* hack that
allows pads to register in any order.

Note that due to the initialization routines, the gamepad will still
likely always get slot 0. Not sure if this can be overridden via config
or not.

== TESTING

Tested locally with GC adapter

2cf89feb86 Code clean-up
== DETAILS

Now that I have a working implementation, it's time to tidy up a bit:

- there was no need for the HID subsystem's object data to have a reference
  to the global hid state (since it's global), so removed it.
- refactored the users of that member to use the global state, defining
  reusable macros.
- reorganized the information in *.h files
- removing the hid state also made the constructor changes to the hid driver
  unneeded, so I reverted those changes.

== TESTING
Confirmed clean build. Haven't tested the build yet to make sure everything
still works, though.

39e4167df6 Start work on DualShock 3 driver
== DETAILS

The WiiU GC adapter is working!

Next up: DualShock 3

I have the skeleton of the driver started, need to work out the
activation packet.

== TESTING

The DS3 driver is broke as hell right now.

1eea48d0c8 Fix crash on exit bug
== DETAILS

Turns out freeing memory that's already been freed is.. bad.

Fix two double-free instances; one due to over-freeing and the other
due to wrong order-of-operations causing a double free.

Also updated logging a little.

== TESTING

The GC adapter still clobbers slot 0, but the "emergency exit" sequence
works to quit RA cleanly.

0100d58ffb WIP: evolve driver implementation
== DETAILS

I've created the concept of a hid_driver_instance_t which is basically
a central place to store the hid pad driver, hid subsystem driver,
the pad list, and the instance data for the above in a central location.

The HID pad device drivers can use it to perform HID operations in a
generic manner.

This is more-or-less a pause point so I can catch up with upstream.

== TESTING

Haven't tested this yet. Compiles without warnings though!
