Earlier RHIDE provided it's own copy of fputc_unfiltered() (which is 
ugly hack of course). Now I changed it to use mem_fileopen() for both 
gdb_stdout and gdb_stderr.

One nuisance:

to get actual positon in ui_file opened with mem_fileopen currently 
only possibility is to retrieve entire buffer with ui_file_xstrdup()
(RHIDE needs to get such position currently). I think it would be nice 
to add something like

	ui_file_xstrlen()

to get length of buffer only (really it's current pointer) like (untested):

long ui_file_xstrlen (struct ui_file *file)
{
  if (file->magic==&mem_file_magic)
    {
       struct mem_file * mem = file->to_data;
       if (mem->magic==&mem_file_magic)
         return mem->length_buffer;
    }
  return 0;
}
