libbeauty: Introduce strarray__strtoul_flags()

Browse source

Counterpart of strarray__scnprintf_flags(), i.e. from a expression like:

   # perf trace -e syscalls:sys_enter_mmap --filter="flags==PRIVATE|FIXED|DENYWRITE"

I.e. that "flags==PRIVATE|FIXED|DENYWRITE", turn that into

   # perf trace -e syscalls:sys_enter_mmap --filter=0x812
