This commit fixes how the USBH handling of a sudden device disconnection,
more specifically handling of device gone.
- Previously the USBH would only halt, flush, and dequeue the device's
default EP, then send a device gone event to the Host Library layer.
- Now the USBH will also halt and flush all non-default EPs, allowing
all of the URBs to be dequeud.
- Some internal object members are now protected by a mutex instead of
a spinlock.

This commit fixes how the USB Host HCD handles sudden disconnections.
Bugs:
- HW channels remain active when the port suddenly disconnects, and
previously the channel would be disabled by setting the disabled bit,
then waiting for a disabled interrupt. However, ISOC channels do not
generate the disabled interrupt when the port is invalid, thus leading
to tasks getting indefinitely blocked in hcd_pipe_command().
Fix:
On a sudden disconnection, forcibly treat all channels as halted even
if their HCCHAR.ChEna bit is still set. We do a soft reset after a port
error anyways, so the channels will eventually be reset.

- This commit adds the API documentation for the USB Host Library.
- Warnings about the beta API are also added.
- usb_host_misc.h renamed to usb_helpers.h
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
This commit moves the mock classes used for HCD unit tests into
a common header so that other layers of the USB Host stack can
also utilzie them for their own unit tests.
This commit fixes the following bugs with the HCD and USB Host HAL
- Make the setting to periodic frame list and scheduling to occur after
a reset command
- All port errors states should put the port into the HCD_PORT_STATE_RECOVERY
state.
- Fixed incorrect return type of hcd_port_command() function
This commit changes the IRP (I/O Request Packet) structure to
the URB (USB Request Block) in order to represent USB transfers
in the host stack. The new URB strcuture:
- Add extra safety with const fields
- Allows each layer of the stack to add their own overhead variables
The HCD layer API and tests have been updated to use this new URB structure
This commit adds support for interrupt and isochronous pipes to the HCD:
- HCD now internally uses double buffering
- Added test cases for interrupt and isochronous transfers
- Reorganized test cases for each transfer type
- Updated API comments and maintainer's notes
Some minor bugs were also fixed
This commit updates the HCD so that transfer requests are no longer used.
The USB IRP object is updated so that the it can be directly passed to the HCD
to start a transfer. HCD API, tests, and documentation updated accordingly.
This commit separates out the common USB types used throughout most of the stack into its
own header file inside the USB component. The types used in the USB HAL are now exclusive
to the HAL.
