The functions that implement usb_request_handlers are already using an
int32_t for transfer_len, so lets make the typedef match. This address
a potential issue in the future when the typedef of int32_t changes (or
when building with newlib).

USB class drivers may need to offload some work from
upcall interrupt context to a background fiber. This
requires some way to defer taking more data from host
till the offloaded work completes. Two APIs are added to
achieve this.
Further USB class drivers sometimes need to set STALL condition
on end-points to signal errors to host.These too are
added.
