Jin Yao 284c4e18f5 perf time-utils: Refactor time range parsing code 
Jiri points out that we don't need any time checking and time string
parsing if the --time option is not set. That makes sense.

This patch refactors the time range parsing code, move the duplicated
code from perf report and perf script to time_utils and check if --time
option is set before parsing the time string. This patch is no logic
change expected. So the usage of --time is same as before.

For example:

Select the first and second 10% time slices:
  perf report --time 10%/1,10%/2
  perf script --time 10%/1,10%/2

Select the slices from 0% to 10% and from 30% to 40%:
  perf report --time 0%-10%,30%-40%
  perf script --time 0%-10%,30%-40%

Select the time slices from timestamp 3971 to 3973
  perf report --time 3971,3973
  perf script --time 3971,3973

Committer testing:

Using the above examples, check before and after to see if it remains
the same:

  $ perf record -F 10000 -- find . -name "*.[ch]" -exec cat {} + > /dev/null
  [ perf record: Woken up 3 times to write data ]
  [ perf record: Captured and wrote 1.626 MB perf.data (42392 samples) ]
  $
  $ perf report --time 10%/1,10%/2 > /tmp/report.before.1
  $ perf script --time 10%/1,10%/2 > /tmp/script.before.1
  $ perf report --time 0%-10%,30%-40% > /tmp/report.before.2
  $ perf script --time 0%-10%,30%-40% > /tmp/script.before.2
  $ perf report --time 180457.375844,180457.377717 > /tmp/report.before.3
  $ perf script --time 180457.375844,180457.377717 > /tmp/script.before.3

For example, the 3rd test produces this slice:

  $ cat /tmp/script.before.3
        cat  3147 180457.375844:   2143 cycles:uppp:      7f79362590d9 cfree@GLIBC_2.2.5+0x9 (/usr/lib64/libc-2.28.so)

Install 'coreutils-debuginfo' to see cat's guts (symbols), but then, the
above chunk translates into this 'perf report' output:

Now lets see after applying this patch, nothing should change:

  $ perf report --time 10%/1,10%/2 > /tmp/report.after.1
  $ perf script --time 10%/1,10%/2 > /tmp/script.after.1

Cool, just the 'perf report' tips changed, QED.
