>Description:
	- sme_register_sensorname doesn't need to handle EMPTY case specially.

	- sme_make_dictionary should fully set up a dictionary before
	 adding it to the array.  (instead of leaving a partial dictionary
	 on errors.)
	 same for sysmon_envsys_createplist and its array.

	- ENVSYS_FDUPDESC seems broken for compat ioctls.

	- what global mutexes like sme_mtx protect is not clear.

	- 'obj' argument of sme_sensor_upstring (and similar functions)
	 is useless.

	- '--sme->sme_nsensors' in sme_update_dictionary seems quite dubious.

	- sysmon_envsys_createplist seems to ignore most errors
	 unless it was for the last sensor in sme_sensor_data[].
	 i don't understand why the last one is special.

>How-To-Repeat:
	code inspection.
