Ubuntu 14 tweak to /proc/timer_stats file code

Ubuntu 14 includes an extra line in /proc/timer_stats which was
ignored by the handler.  This update adds a new field to pick up
the "collections" setting, includes new JSON/CSV verification
files, and adds code to the recreator to conditionally generate the
new line if was presented in the source data file.
Add script to run all available "regentest" code

There's also a tweak to "recreate-proc-file" that makes it a bit
smarter in how it handles requests to regenerate /proc files that
are symlinks.  Those aren't handled by recreators so they just get
an error messsage.  But prior to this update the error message
given was inaccurate.
