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.
* defs.h (memcmp): Add decl for memcmp to #ifndef MEM_FNS_DECLARED.
* findvar.c (write_register): See if we are writing back the same
value that's already in the register. If so, don't bother.
* remote.c (putpkt, getpkt): Improve handling of communication
problems.
* ser-go32.c: Prototype it to death. Update serial_ops and add
dummy routines where appropriate.
* ser-tcp.c: New module to implement serial I/O via TCP
connections.
* ser-unix.c: Clean up getting/setting of tty state. Get rid of
SERIAL_RESTORE, add SERIAL_{GET|SET}_TTY_STATE interfaces.
* serial.c: Add start of support for connect command.
(serial_open): Distinguish between tcp and local devices.
* serial.h (struct serial_ops): Get rid of restore, add
get_tty_state and set_tty_state. Define protoypes and macros for
this mess.
* gdbserver/remote-utils.c: Add tcp support. (readchar): Do
some real buffering. Handle error conditions gracefully.
* gdbserver/remote-inflow-sparc.c: Update to remote-inflow.c
(Lynx), remove lots of cruft.
