The perf annotate browser on TUI can identify a jump target for a selected instruction. It assumes that the jump target is within the function but it's not the case of PLT symbols which have offset out of the function as a target. Since it caused a segmentation fault, do not try to follow jump target on the PLT symbols.

That given two hists will find the hist_entries (buckets) in the second hists that are for the same bucket in the first and link them, then it will look for all buckets in the second that don't have a counterpart in the first and will create a dummy counterpart that will then be linked to the entry in the second. For multiple events this will be done pairing the leader with all the other events in the group, so that in the end the leader will have all the buckets in all the hists in a group, dummy or not while the other hists will be left untouched.

We want to match more than two hists, so that we can match more than two perf.data files and moreover, match hist_entries (buckets) in multiple events in a group. So the "baseline"/"leader" will instead of a ->pair pointer, use a list_head, that will link to the pairs and hists__match use it.

Arnaldo reported that annotation during perf top resulted in a segfault. It was because the env->arch was NULL and we don't set it for a live session. In fact, no need to look up objdump in this case since we can use system's default (native) objdump.

Currently various hist browser functions receive 3 arguments for refreshing histogram but only used from a few places. Also it's only for perf top command so that it can be NULL for other (and probably most) cases. Pack them into a struct in order to reduce number of those unused arguments. This is a mechanical change and does not intend a functional change.

David reported that perf report for i686 target data on x86_64 host failed to work because it tried to find out cross-compiled objdump. However objdump for x86_64 is compatible to i686 so that it doesn't need to do it at all. To prevent similar artifacts, normalize arch name when comparing host and file architectures.
