189899180f usb: Change API and refactor tests 
This commit updates the USB Host Library API in the following wasy:
- usb_host_client_handle_t and usb_device_handle_t made into struct pointers
  to generate compiler warnings about conflicting handle types
- usb_host_client_config_t changed to future proof API for Synchronous Clients
- Added usb_host_lib_unblock()
- Added usb_host_device_addr_list_fill()
- Return of usb_host_device_free_all() updated to indicate whether there
  are still devices yet to be freed.
- Blockg APIs are now marked explicitly
- Fixed a bug in usb_host_transfer_submit_control() when checking the bEndpointAddress
  of a control transfer.

Tests are also refactored to move some common macros into shared headers

accbaee57c Add USB Host Library 
This commit adds the preliminary version of the USB Host Library. This commit contains:

- USBH (USB Host Driver)
- Hub Driver that only supports a single device and device enumeration
- USB Host Library (asychronous API)
- Test cases for USB Host Library asychronous API

The following changes were made to the existing HCD:
- Removed HCD_PIPE_STATE_INVALID. Pipes are no longer invalidated
- Changed pipe commands to halt, flush, and clear. Pipes need to be manually
  halted, flush, and cleared.
- Halting and flushing a pipe will execute the pipe callback if it causes a
  HCD_PIPE_EVENT_URB_DONE event
