> 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:
