[RFA] cli-out.c new function

[Elena Zannoni <ezannoni@redhat.com>]

This function sets the stream of the uiout file to the given
parameter.  It is used in the interpreter work. Maybe Keith or JimI
can explain this a bit better, but switching interpreters can change
the gdb_sdout.


  /* gdb_stdout could change between the time cli_uiout was initialized
     and now. Since we're probably using a different interpreter which has
     a new ui_file for gdb_stdout, use that one instead of the default.

     It is important that it gets reset everytime, since the user could
     set gdb to use a different interpreter. */
  old_stream = cli_out_set_stream (cli_uiout, gdb_stdout);
