Hi

These are some changes I have accumulated in the last
weeks. Mostly improving the tool's user experience.

 - On timerlat top, remove an extra \n that was breaking
   the output.

 - Replace \t with '       ' on the auto analysis, fixing some
   copy & paste.

 - On timerlat top, do not print TTY formatting characters when
   the output is not sent to a terminal, because they break the
   output.

 - on timerlat top and hist, add a summary with the overall results.
   For instance, the minimum value for all CPUs, the overall average
   and the maximum value from all CPUs.

 - Add a --warm-up <seconds> option, allowing the workload to run for
   <seconds> before starting to collect results.

 - Add a --trace-buffer-size option, allowing the user to set the
   tracing buffer size. This is mainly useful for reducing the trace
   file.

 - Make the user-space threads the default choice, also adding the
   a -k option, allowing the user to switch to kerne-threads.
