* Project: fix release build, replace asserts with checks. * FuriHal: i2c refactoring, new bus access model, flexible bus gpio configuration. * FuriHal: set i2c pins to high on detach. * FuriHal: more i2c bus events, put bus under reset when not used, move bus enable/disable routine to bus handler. * FuriHal: fix i2c deadlock in power api, add external i2c handle.
