[RFA] fix session breakpoints

["Martin M. Hunt" <hunt@redhat.com>]

I often use Insight to debug itself. After a few hundred times, things get a 
bit slow as Insight sets a few hundred breakpoints on info_command and internal_error.
So here's a simple patch.  It not only stops these breakpoints from accumulating but 
will also eliminate them from .gdbtkinit.

	* library/session.tcl (SESSION_serialize_bps): Ignore
	breakpoints set on internal_error and info_command because
	these are set by .gdbinit and will be recreated by it.
