[PATCH 3/3] Introduce bfd_print_error function

[Nick Clifton]

Hi Tom,

> gdb likes to control its own output; for example, this is important
> for gdb's pager, and for logging.  While BFD provides a way to
> intercept error output, via bfd_set_error_handler, it turns out to be
> difficult for this function to truly generate the desired output in a
> gdb-friendly way -- the error handler is expected to implement some
> BFD printf format extensions.
> 
> This patch introduces a new function that an error handler can use to
> format the text.  This way, gdb can set the error handler and arrange
> for the output to be displayed as it likes.
