perf parse-events: Improve error message for bad numbers
Use the error handler from the parse_state to give a more informative
error message.
Before:
$ perf stat -e 'cycles/period=99999999999999999999/' true
event syntax error: 'cycles/period=99999999999999999999/'
\___ parser error
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event> event selector. use 'perf list' to list available events
After:
$ perf stat -e 'cycles/period=99999999999999999999/' true
event syntax error: 'cycles/period=99999999999999999999/'
\___ parser error
event syntax error: '..les/period=99999999999999999999/'
\___ Bad base 10 number "99999999999999999999"
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event> event selector. use 'perf list' to list available events
