It's follow-up patches to improve the perf time slice feature
(perf report/script --time xxx)

1. Improve the error message
    perf report: Improve error msg when no first/last sample time found
    perf script: Improve error msg when no first/last sample time found

2. Fix an issue that illegal percent was accepted previously (e.g. 1abc%)
    perf util: Improve error checking for time percent input

3. Omit the slice index if possible. For example,
    perf report --stdio --time 10%/1 is equivalent to
    perf report --stdio --time 10%

    perf util: Support no index time percent slice

4. Add indication of time slices in perf report header.
    perf report: Add an indication of what time slices are used
>>> 5. Remove the time slices number limitation in perf report/script
    perf util: Allocate time slices buffer according to number of comma
    perf report: Remove the time slices number limitation
    perf script: Remove the time slices number limitation

from quick look it looks ok
