* Fix ChibiOS control OUT buffer sizing. Some ChibiOS low level drivers (STM32 USBv1, WB32, Kinetis) write a whole control packet into the EP0 OUT buffer rather than only the requested length, so the buffer must hold a full packet. SET_REPORT and SET_LINE_CODING now share one packet-sized buffer, and line coding is copied out on transfer completion so a short data stage cannot leave it partly overwritten. * Use exact size. * Recover some RAM on failing builds.
