* remote.c: Add arg names to prototypes, in a modest effort at
clarification. Also add prototypes for some new functions.
* (remote_wait): Better error reporting for 'T' responses.
* ser-go32.c (strncasecmp): Make str1 & str2 be const.
* (dos_async_init): Make usage message reflect requested port #.
* ser-tcp.c (tcp_open): Terminate hostname properly to prevent
random hostname lookup failures. Add nicer message for unknown
host error. (wait_for): Wake up in case of exceptions. Also,
restart select() if we got EINTR.
* ser-unix.c (wait_for): Restart select() if we got EINTR.
* serial.c: (serial_close): Clean up code.
