Make hwmon work with double or int64 interface

Deduce type based on interface using decltype
and if it is double apply scale to the value.

Tested-by: Noticed that on dbus using busctl and debug
server that doubles were produced and scaled.

Also verifed that hwmon still produced int64_t values when
building with current phosphor-dbus-interfaces.

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.
