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.
