Overhaul UART API

MGMT is the default UART, and no one should have to explicitly refer to
the UART unless they need USER (hsm.c:hal_serial_send_char).

The default UART is now exposed in the header file, so that the
default-using functions can be macros, which saves a few bytes in code
space, and a few microseconds in function call overhead.
