Please backport eventstat 0.02.00-1 (universe) from wily

[Colin Ian King]

Please backport eventstat 0.02.00-1 (universe) from wily to vivid.

Reason for the backport:
========================
eventstat is used in ubuntu-touch for finding wakeup event power
regressions and will be a key QA/CI tool for regular phone
image testing. In order to make it useful to the QA process I have
optimised eventstat to use less CPU and memory resources and also
added a new -w option to timestamp events to help QA correlate
events with other logs gathered during testing.

Key features added and fixed since 0.01.35:

    Re-order man page options into alphabetical order
    Add -w "whence" timestamp row
    Add time column to CSV output
    Fix resource leak on file descriptor on error exit path
    Add auto-purge of old state timer stats to stop memory growth
    Speed up reading and parsing of the timer stat data
    Add some performance optimisations, better hashing and heap management
    Make hash ident a few bytes smaller for marginal compare speedup
    Replace hash function with one that is 3.3x faster
    Fix hash chain growth by comparing with ident rather than an NULL field
    Free cmdline on mask check continue path
    Remove SIGSEGV from trapped signals list
    Fix memory leak on cmdline, found by CoverityScan
    Improve kernel thread detection and hash on unmodified task name (LP: #1467932)
    Remove overzealous signal handlers for SIGBUS, SIGABRT, SIGILL

eventstat is a standalone binary and has no other dependancies. Built and tested
using backportpackage -u ppa:colin-king/backports -s wily -d vivid eventstat

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 eventstat

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

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