(net_close, net_read_prim, net_write_prim): Make global. (net_open): Likewise. Pass an exception set to select. Whitespace fix. Document why we can not use gdb_select. (_initialize_ser_tcp) [USE_WIN32API]: Do not register TCP support here. * ser-tcp.h: New file. * inflow.c (gdb_has_a_terminal): Don't initialize stdin_serial here. (handle_sigio): Use gdb_select. (initialize_stdin_serial): New function. * terminal.h (initialize_stdin_serial): New prototype. * top.c (gdb_init): Call initialize_stdin_serial. * mingw-hdep.c (gdb_select): New function, moved from gdb_select in event-loop.c. Add exception condition support. Use serial_for_fd and serial_wait_handle. Fix timeout handling. * posix-hdep.c: Include "gdb_select.h". (gdb_select): New function. * remote-st.c (connect_command): Use gdb_select. * ser-unix.c: Include "gdb_select.h". (hardwire_send_break, wait_for): Use gdb_select.
