mainloop: add uniqueness to busname There can be multiple daemon instances that have the same devpath which leads to a collision which errors silently. This adds uniqueness to the path, which was no longer human-readable to avoid this collision situation. Tested: Ran on quanta-q71l with unique devices and two instances pointing to the same device and it correctly set them up with unique but deterministic bus names.

Exposes generic hwmon entries as DBus objects.
To build this package, do the following steps:
1. ./bootstrap.sh
2. ./configure ${CONFIGURE_FLAGS}
3. make
To clean the repository run `./bootstrap.sh clean`.
To enable the use of Linux features like cgroups prioritization and udev/systemd control, one instance of phosphor-hwmon is intended to be run per hwmon sysfs class instance. This requires an algorithm for selecting a stable, well-known D-Bus busname. The algorithm is <PREFIX>-<ID>.Hwmon<N> where PREFIX is an autoconf configurable prefix (BUSNAME_PREFIX, xyz.openbmc_project by default), ID is a std::hash of the /sys/devices path backing the hwmon class instance, and N is the implemented phosphor-hwmon D-Bus API version.
