Log Message:
Add a new sensor type to sysmon_envsys(9): ENVSYS_GSTRING.

ENVSYS_GSTRING (aka Generic String) uses the genstr member in
the envsys_data_t struct to add a generic string that envstat(8)
will show as value or state.

It's like the ENVSYS_DRIVER, but doesn't use value_cur. Below
is the dictionary created on these sensors:

<dict>
	<key>description</key>
	<string>acpibat0 charge state</string>
	<key>generic-state-string</key>
	<string>NORMAL</string>
	<key>monitoring-supported</key>
	<false/>
	<key>state</key>
	<string>valid</string>
	<key>type</key>
	<string>Generic string</string>
</dict>

Note that it's limited to 32 chars, but we can grow it if needed.

envstat(8) will print ENVSYS_GSTRING sensors as:

$ envstat -dacpibat0 -s"acpibat0 charge state"
  acpibat0 charge state:     NORMAL
$
