Host edpt xfer #1403

hathach · 2022-03-19T10:35:32Z

Describe the PR

More major changes for host stack transfer, include support for generic endpoint transfer.
tuh_control_xfer(), tuh_edpt_xfer() and callback follow similar API with 1 unique tuh_xfer_t following the libusb convention https://libusb.sourceforge.io/api-1.0/group__libusb__syncio.html
- required CFG_TUH_API_EDPT_XFER=1 since it requires 8 more bytes per endpoint
- does not requires to alloc or keep the xfer struct memory lasting for transfer to complete (usbh will keep a copy of required fields).
- to save sram, not all xfer struct is available for use in callback
- timeout not supported yet (maybe later).
