acpi: implement -ctV, fix recursion, plug a small leak
* acpi_callback had blindly assumed that a path of 26 chars or more was the right depth; rely on depth from dirtree root * acpi -c shows cooling device state some backlights are set up so that they will report dimmer as higher, but that's a hardware issue that can't be sanely worked around. * acpi -t shows temperatures this implementation will pick up fan, battery temperatures, etc. (but currently not hwmon-type temperatures, or hdd temps; acpi 1.7 does not measure these either) we handle milli-C (typical) and deci-C (I've seen this on Qualcomm batteries, and not yet anywhere else) we do *not* handle deci-K yet * acpi -V shows all sensors * without saving the result of dirtree_path() to free later, we had a slow leak. all callbacks call this once, so save it in GLOBALS() acpi -t happens to need this anyhow, though using openat()/readall() instead of readfile() would work.
