Please backport powerstat 0.02.03-1 (universe) from wily

[Colin Ian King]

Please backport powerstat 0.02.03-1 (universe) from wily to vivid.

Reason for the backport:
========================

powerstat is used in ubuntu-touch for measuring power and system
activity regressions and is hence a useful QA/CI tool for regular phone
image testing. Over the past months I have added more useful features
into powerstat to measure temperature thermal zones, CPU frequencies,
improved histogram reports as well as improved child/thread detection
and C state measuring. All in all, this is an improved tool and is
very useful for power regression checking.

Changes in updated powerstat:
  * Handle read errors from reading comm and/or cmdline files
  * manual: improve the -z option
  * Add -a (all) option
  * When using -z, set sample delay to zero if not specified
  * ensure we don't get buffer overflow on comm and cmdline reads
  * Add thread/child detection, add better proc name fetching
  * Fix power formatting when E estimate is being displayed
  * Check for insane temperatures, set to zero if out of range
  * Re-enable -z option
  * Add thermal zone temperature monitoring
  * Add CPU frequencies to histogram mode
  * Update date on manual
  * Don't divide by floating point zero, clarify CPU freq average calculation
  * Add check to ensure we don't free scandir list when no entries found
  * Fix a couple of warnings found on ARM builds
  * Add the -n no headings option
  * Add in a new -f CPU frequency option
  * Ensure we scan a buffer correctly
  * Add -c "C-state" option
  * Make statistics #defines into a stat_type enumeration
  * Specify integer types with stdint int types
  * Clean up comments, add more comments where necessary
  * pass tv into double_to_timeval rather than returning a timeval struct
  * Remove "Battery" from message since we can measure using RAPL
  * Remove signal handling for SIGILL, SIGABRT
  * Fix typo and update date in man page
  * Add CPU consumption stats to -H mode
  * Fix up style warnings from cppcheck
  * Fix up default start delay duration for RAPL
  * Update date in manual
  * Add more precision to RAPL domain stats
  * Remove rapl_rates, stash per domain stats directly
  * Add -H histogram option
  * Only accumulate RAPL package power for total Watts in -R mode
  * Move fclose to fix a resource leak
  * Allow all RAPL power domains to be printed
  * Prevent RAPL wrap around the correct way
  * Handle -ve values from RAPL
  * Cater for systems (such as VMs) that have RAPL interface but no domains
  * Add -R RAPL power measurement option

Testing:
========
Mark off items in the checklist [X] as you test them, but please leave the checklist so that backporters can quickly evaluate the state of testing.

You can test-build the backport in your PPA with backportpackage:
$ backportpackage -u ppa:<lp username>/<ppa name> -s wily -d vivid powerstat

* vivid:
[X] Package builds without modification
[X] powerstat installs cleanly and runs
[ ] powerstat-dbgsym installs cleanly and runs

Reverse dependencies:
=====================
The following reverse-dependencies need to be tested against the new version of powerstat. For reverse-build-dependencies (-Indep), please test that the package still builds against the new powerstat. For reverse-dependencies, please test that the version of the package currently in the release still works with the new powerstat installed. Reverse- Recommends, Suggests, and Enhances don't need to be tested, and are listed for completeness-sake.
