    560235 Support "jump to"
    
    	* src/common/nmv-loc.h: New location type declarations.
    	* src/common/Makefile.am: Add it to build system.
    	* src/dbgengine/nmv-i-debugger.h (IDebugger::DefaultSlot)
    	(IDebugger::BreakpointsSlot, IDebugger::LocSlot): New slot
    	typedefs.
    	(IDebugger::jump_to_position): New entry point.
    	(IDebugger::set_breakpoint, IDebugger::enable_breakpoint): New
    	overloads taking callback slots.
    	* src/dbgengine/nmv-gdb-engine.h (GDBEngine::jump_to_position)
    	(GDBEngine::set_breakpoint, GDBEngine::enable_breakpoint): Declare
    	these functions.
    	* src/dbgengine/nmv-gdb-engine.cc (location_to_string): New
    	function overloads to generate a GDB location string for each type
    	of location.
    	(OnBreakpointHandler::do_handle): Support callback slots for
    	commands 'set-breakpoint', '-break-enable' and 'jump-to-position'.
    	(GDBEngine::jump_to_position): Define new function.
    	(GDBEngine::set_breakpoint): Add new overload that takes a
    	callback slot and an instance of location type.
    	(GDBEngine::enable_breakpoint): Likewise.  Rewrite the other
    	overload in terms of this one.
    	(null_disass_slot): Move this to nmv-debugger-utils.cc
    	* src/dbgengine/nmv-debugger-utils.h ((null_default_slot,
    	null_disass_slot, null_breakpoints_slot): Declare new functions.
    	* src/dbgengine/nmv-debugger-utils.cc (null_default_slot)
    	(null_disass_slot, null_breakpoints_slot): Define new functions.
    	* src/persp/dbgperspective/nmv-dbg-perspective.cc
    	(DBGPerspective::on_jump_to_current_location_action)
    	(DBGPerspective::on_jump_and_break_to_current_location_action)
    	(DBGPerspective::on_break_before_jump)
    	(DBGPerspective::do_jump_to_current_location)
    	(DBGPerspective::do_jump_and_break_to_current_location)
    	(DBGPerspective::jump_to_location): New functions.
    	(DBGPerspective::on_debugger_breakpoints_set_signal): Minor style
    	cleanup.
    	(DBGPerspective::init_actions): Add
    	JumpToCurrentLocationMenuItemAction and
    	JumpAndBreakToCurrentLocationMenuItemAction actions.
    	(DBGPerspective::get_contextual_menu): Add two new menu items for
    	actions JumpToCurrentLocationMenuItemAction and
    	JumpAndBreakToCurrentLocationMenuItemAction.
