White space and style fixes

	* src/dbgengine/nmv-gdb-engine.cc (GDBEngine::Priv::list_frame):
	Remove useless white spaces.
	(OnDetachHandler::do_handle): Do not name the unused "a_in" parm.
	Thus remove the dummy if().
	* src/persp/dbgperspective/nmv-dbg-perspective.cc
	(DBGPerspective::on_debugger_inferior_re_run_signal): Remove
	useless white spaces.
	(DBGPerspective::on_debugger_detached_from_target_signal): Add a
	';' after  NEMIVER_TRY.
698371 Run command is available even after detaching

	* src/dbgengine/nmv-gdb-engine.h (GDBengine::reset_command_queue):
	New entry point.
	* src/dbgengine/nmv-gdb-engine.cc
	(GDBEngine::reset_command_queue): Implement this new entry point.
	(GDBEngine::load_program): Use this new reset_command_queue entry
	point.
	(GDBEngine::detach_from_target): Normally, the inferior must be
	stopped before accepting commands; soo to accept the "detach"
	command, the target must be stopped too.  Thus, if the target is
	not stopped, let's stop it first by sending it a SIGINT signal,
	end schedule the detach command to be sent to GDB right after
	that.
	(OnDetachHandler::do_handle): Reset command queue upon detach.
	* src/persp/dbgperspective/nmv-dbg-perspective.cc
	(DBGPerspective::init_actions): Remove the
	s_target_not_started_action_entries.  Move the RunMenuItemAction
	into the s_debugger_ready_action_entries object. Remove
	m_priv->target_not_started_action_group.
	(DBGPerspective::on_engine_died_signal)
	(DBGPerspective::update_action_group_sensitivity): Adjust for
	removing the target_not_started_action_group action group.
	(DBGPerspective::on_debugger_detached_from_target_signal): Closed
	opened file only upon detach from target.  Adjust for removing the
	target_not_started_action_group action group.
