* USB-UART: new gui * Furi: use furi_console for logging instead of printf. * CDC: calling open/close callbacks on interface change * fix vcp_tx block on disconnect * USB mode set by struct pointer * FuriHal: proper event sequence on vcp reconnect * disable debug prints * HAL: add context to UART IRQ's * Context usage in UART IRQ and CDC callbacks * USB-UART: geting rid of baudrate limitations * FuriHal: remove struct pollutant in usb api.
