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
