Function calculate_energy_model (no longer) uses the program
options structure. It may have been used earlier for the
verbosity control in some messages, but that system has been
reworked. Remove the unused paramter.

Many of the source files were missing copyright headers. Headers have been
added to all .c and .h files and existing headers were updates with
contributor information.
The version number was bumped up to 0.5 due to having many new features
since last version number update.

Pre-patch the topology is rooted to a global variable g_cpu_topo_list.
This prevents loading multiple traces for comparison. This patch
makes the allocation dynamic. The root pointer is stored within
struct cpuidle_datas, allowing the idlestat_load() to retain its
prototype, but most of the functions defined in topology.c have
a new parameter for passing the topology root pointer.

This is a port of Patrick Bellasi's energy model improvements
to the current idlestat tip. These are taken from
his idlestat tree which is located at
git@github.com:scheduler-tools/idlestat.git
The commits used are listed below. They were squashed, ported
and some cleanup was performed.
Some very TC2-specific code (hwmon) was removed -- it may
be possible in the future to generalize this to make it useful
to all platforms.

energy_model: fix scaling of wakeup energy components
This should fix the scaling of wakeup energy components to match the
energy model parameters.
Basically, since the scheduler model is normalized to a wake-up rate of
1000 wake-ups per second, the correct conversion is:
idlestate_wakeup_energy = sched_wakeup_energy * 47742 / (1000 * 1024)
Where:
- 47742: Removes wake-up tracking pre-scaling
- 1024: Removes << 10
- 1000: Single wake-up instead of 1000/s

energy_model: switch to tabular output
Use by default a tabular output for the computed energy components.
This is expected to improve readability and debugging of the energy

If the energy model file doesn't exist, instead
make an energy model template file (taking the
topology and C and P-state names/values into account).
This file is similar to an energy model file, except that
all of the energy costs are to be filled in (and are shown
as "?").
