use xsnprintf instead of snprintf.
snprintf is not available on LynxOS, so I changed the calls to snprintf to calls to xsnprintf, which should be strictly equivalent. gdb/gdbserver/ChangeLog: * utils.c (xsnprintf): Make non-static. * server.h: Add xsnprintf declaration. * linux-low.c, nto-low.c, target.c, thread-db.c, tracepoint.c: replace calls to snprintf by calls to xsnprintf throughout.
