Document and extend readline-bindable functions 

This adds readline-bindable function names to a few gdb functions that
already had key bindings.  This lets users change the bindings.

This also removes the gdb-command function.  Due to how this function
is implemented, it doesn't make sense to allow binding it.

Finally, this updates the documentation to reflect these changes.
