(Part 1: API) * Support for detachable sensors. * Cleaned up the API for simplicity and efficiency. * Ability to send capacity/critical/warning events to powerd(8). * Adapted all the code to the new locking order. * Compatibility with the old envsys API: the ENVSYS_GTREINFO and ENVSYS_GTREDATA ioctl(2)s are supported. * Added support for a 'dictionary based communication channel' between sysmon_power(9) and powerd(8), that means there is no 32 bytes event size restriction anymore. * Binary compatibility with old envstat(8) and powerd(8) via COMPAT_40. * All drivers with the n^2 gtredata bug were fixed, PR kern/36226. Tested by: blymn: smsc(4). bouyer: ipmi(4), mfi(4). kefren: ug(4). njoly: viaenv(4), adt7463.c. riz: owtemp(4). xtraeme: acpiacad(4), acpibat(4), acpitz(4), aiboost(4), it(4), lm(4).
