Pass stderr of program run with "target remote |"
via gdb_stderr. * serial.c (serial_open): Set error_fd to -1. * serial.h (struct serial): New field error_fd. (struct serial_opts): New field avail. * ser-pipe.c (pipe_open): Create another pair of sockets. Pass stderr to gdb. * ser-mingw.c (pipe_windows_open): Pass PEX_STDERR_TO_PIPE to pex_run. Initialize sd->error_fd. (pipe_avail): New. (_initialize_ser_windows): Hook pipe_avail. * ser-base.c (generic_readchar): Check if there's anything in stderr channel and route that to gdb_stderr.
