6ab91a422e Small cleanup to adapt to upstream code changes
retro_bits_t turned into input_bits_t and there were parts of my
code that needed to update.

== TESTING
No idea if upstream changes broke anything, but it compiles cleanly
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.

4433cbebc6 Get digital inputs for Sony DualShock 3 working
== DETAILS

- fix the bitshift math
- read the right bytes out of the ds3 data packet
- remove verbose logging in critical path
- stop caring about errors in the hid read loop -- seems to just
  be benign "device not ready" -- or at least, that's what I'm assuming
  given that the read eventually succeeds.

== TESTING
Played Mario 3 with the DS3 with no issues.

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.

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.

180d6a28bf Fix up HID device driver initialization
== DETAILS
Turns out the cause of the crash was a bad cast, resulting in a
function call to nowhere.

Also, I think the DSI exception handler only works on the primary core;
when this was happening in the background thread, I got a black
screen error instead.

Next up: finishing up the GCA driver.

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!

41ce8853d7 Add name for hid device; implement detect
== DETAILS

- detect() methods in device_* files now check for VID/PID
  instead of just returning false
- add "name" field on hid device, mainly for logging purposes

== TESTING
Verified my WiiU GC adapter detected properly
