Add function to handle a new input history record

This function will take a raw input power history
record and add it to the record manager cache.

The record manager will parse the raw record, validate
its sequence ID, and place it in the front of its
internal queue. It prunes its queue if it needs to
or clears it out if the sequence ID is out of order.

Add function to convert from linear format

The average and maximum power values are returned from the
power supply in Watts specified in linear format. The values

Add function to convert from linear format

The average and maximum power values are returned from the
power supply in Watts specified in linear format. The values
must be converted from linear format to be useful. The value
will be converted to an integer, keeping the units as Watts.

Linear format is a 16 bit value made up of 5 bits of exponent
followed by 11 bits of mantissa, where the value is:
X = mantissa * 2^exponent

These values are specified as two's complement, and technically
may be negative, though there isn't really a reason for a power
supply to specify negative power values. The code will support
them anyway for completeness, and to be helpful to future code
that may need to for sure.

Add history::RecordManager class

This class will manage the records for the input power
history that has to be maintained on D-Bus. This includes
the average power and maximum power over 30 second intervals.

The actual power values come from the power supply, and the
PowerSupply class will pass that data to this class every time
it is read, which is faster than the data actually changes since
it only changes every 30s. This class will only save new data
when it has changed.

If there is new data available, this class will let the caller
know that it should then ask for the D-Bus property values for
the maximum and average power values, which are each arrays with
entries made up of timestamps along with the values.

This commit just includes some base functionality. The rest will
come in future commits.
