	Merging debugger enhancements previously in separate
	`guile-debugger' package ...
	
	* debugger.scm: Factored out into the following constituent parts

	(*not-yet-introduced*): New (avoids repeatedly introducing the
	debugger when entering it from breakpoints).
	(debug-stack): New.
	(debug): Rewrite to use more general `debug-stack'.

	* debugger/commands.scm, debugger/command-loop.scm,
	debugger/state.scm, debugger/utils.scm: New files containing bits
	of old (ice-9 debugger), plus some rewriting and enhancements for
	breakpoint support ...

	* debugger/state.scm (state-rtd): Add flags field.
	(make-state): Extend to optionally take flags.
	(state-flags): New, accessor for flags field.
	(set-state-index!, set-stack-index!): New.
	(write-state-short): Rewritten to print out the current source
	location in a way that is more easily trackable by Emacs.
	
	* debugger/commands.scm (assert-continuable, continue, finish,
	trace-finish, step, next): New debugger commands for continuing
	execution from a breakpoint.

	* debugger/behaviour.scm, debugger/breakpoints.scm,
	debugger/breakpoints/procedural.scm,

	* boot-9.scm (top-repl): Use 2 as the limit when saving the stack.
