Jacob Alexander 358d480ea9 Major USB update, fixes most (if not all) known issues
USB - General
- Refactored descriptors
- Enabled/Disable USB endpoints
- Added debug flags for special features
- Code cleanup
- Interface count calculation based off of enabled endpoints
- Delayed wTotalLength calculation to simplify descriptor offsets
- Re-ordered endpoints and interfaces
- Added more debug output
- Added usbInitTime to show how long keyboard initialization took
  (Useful when debugging bad init sequences)
- Added function for usb_resume() which takes care of the resume sequence
  * Resume is now only called if packets are starting to timeout

USB - Special Options
- Added enableDeviceRestartOnUSBTimeout
  * A last resort hammer for bad USB Chipsets/OSs, don't use if you can help it
  * Disabled
- Added enableUSBResume
  * Enables host resume wake-up signalling, required to wake a computer from sleep
  * Enabled
- Added enableUSBLowPowerNegotiation
  * Enables power negotiation hack
  * Required to use firmware with an IPad and other hard-limit low-power USB hosts
  * Hasn't been tested with the recent changes
  * Disabled
- Added enableUSBSuspend
  * Enables power down events on host USB bus suspend
  * Enabled

USB - Keyboard
- Attempted to cleanup HID SET_REPORT
  * Works much better
  * Still has an issue under Linux which generates *a lot* of NAKs (initializes quickly regardless)
    + Not present on other keyboards
    + SETUP -> OUT -> IN : This sequence is the problem
    + Specifically during the OUT phase
- Enabled

USB - CDC Virtual Serial Port
- Code cleanup
- Added convenience struct USBCDCLineCoding for easier debugging
- Attempted to cleanup CDC_SET_LING_CODING
  * Works much better
  * Still has an issue under Linux which generates *a lot* of NAKs (initializes quickly regardless)
    + SETUP -> OUT -> IN : This sequence is the problem
    + Specifically during the OUT phase
    + Likely the same issues as HID SET_REPORT
- Enabled

USB - Mouse
- Enabled

USB - Joystick
- Disabled

USB - RawIO
- Initial code, API not used yet
- Disabled

DFU
- Updated load script, now faster
