leon, cons: drvmgr cons interface uses new TERMIOS
LEON driver manager console driver interface (cons) and the APBUART cons driver (apbuart_cons) have been updated for recent TERMIOS interface changes. The legacy callback API is not used anymore and deprecated functions are eliminated. This new implementation is based on RTEMS BSP and Device Driver Development Guide, chapter named "Console Driver". - Functions marked as deprecated (rtems_termios_open() and rtems_termios_close()) have been updated with the present-day versions. - The legacy "callback" interface is replaced with the "handler" interface. - Implementation is inspired by the documentation example, the non-driver manager driver for APBUART (apbuart_termios). - Polled, interrupt and task mode is supported.
