    Remove dead code and "current" field from MI thread output doc
    
    The MI documentation says that -thread-info output contains a "current"
    field in the current thread tuple, with the value "*".  Current GDB
    master does not do this, and I couldn't find any GDB version that did.
    I suspect that it was never the case.
    
    The code that would correspond to this in print_thread_info_1 is
    essentially dead code.  The calls to uiout->text end up in
    mi_out::do_text, which is empty.
    
    This patch removes the documentation bit and the dead code.  This
    "current" field is not necessary, since -thread-info outputs a
    "current-thread-id" field.
    
    gdb/ChangeLog:
    
    	* thread.c (print_thread_info_1): Remove dead code.
    
    gdb/doc/ChangeLog:
    
    	* gdb.texinfo (GDB/MI Thread Commands): Remove "current" field
    	from -thread-info output.
