sensor: to enable testing receive hwmonio interface pointer

The sensor objects all share a reference to the mainloop's ioAccess
object.  To enable testing, the sensor object needs to expect the base
pointer to this object.

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.
