Revise signal mapping function in GDB interface for RX sim.
sim/rx/gdb-if.c had a function named `rx_signal_to_host'. This function mapped signal numbers used by the BSP to host signal numbers which, at one time a while back, were used by GDB as target signal numbers. This change updates the signal numbers returned to be those names prefixed with "GDB_SIGNAL_" as defined in include/gdb/signals.h. It also changes the name of the function somewhat to better match what the function currently does. I noticed that this function is not static - and there's no reason for it not to be - so I made it static too. * gdb-if.c (rx_signal_to_host): Rename to `rx_signal_to_gdb_signal'. Make static. Update all callers to use new name. Use signal names from include/gdb/signals.h.
