Currently we don't properly display hist data with symbol_conf.field_sep
separator. We need to display either space or separator.

When loading symbols in a data mapping, ABS symbols (which has a value
of SHN_ABS in its st_shndx) failed at elf_getscn(). And it marks the
loading as a failure so already loaded symbols cannot be fixed up.
I'm not sure what should be done. Just ignore them for now. :)

When mmaping multiple events we need to find the right evsel that
matches an event in the ring buffer.
For that we need to set the PERF_FORMAT_ID bit in
perf_event_attr.read_format so that when we read the event fds we get
that id to then hash it and be able later

Current hists__match/link() link a leader to its pair, so if multiple
pairs were linked, the leader will lose pointer to previous pairs since

We use evsel->sample_size to detect underflows in
perf_evsel__parse_sample, but we were failing to update it after
perf_evsel__init(), i.e. when we decide, after creating an evsel, that
we want some extra field bit set.
Fix it by introducing methods to set a bit
From: Namhyung Kim
Fix a misplaced underscore. In this case, 'hist_entry' is the name of
data structure and we usually put double underscores between data
structure and actual function name.
