Tested:
    Sensor objects are created and stored for each sensor

Exposes generic hwmon entries as DBus objects.

To Build

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`.

D-Bus bus names

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.
