This series contains the remaining 6 unmerged patches from our UI, hists,
and annotate fix series. Upstream maintainer Namhyung Kim applied patches
1-6 (except patch 4) from the v6 series into perf-tools-next.

This v7 series includes:
  - Fix stack use-after-return for symbol_filter_str by duplicating with
    strdup() and freeing during evsel destruction in hists_evsel__exit().
  - Guard against NULL hist_entry in add_script_opt() when trace is empty.
  - Populate map_symbol thread in report UI with proper reference counting
    (map_symbol__copy, thread__get) and memset zeroing in
    free_popup_actions().
  - Fix dso_filter reference leak and exit zoom cleanup.
  - Robust cross-platform disassembly fallback when annotating without a
    thread.
  - Remove duplicated thread member from struct popup_action (placed at the
    end of the series per reviewer feedback).

v7 Changes:
  - Rebased onto latest perf-tools-next (after patches 1-3, 5-6 were
    merged).
  - Move symbol_filter_str teardown to hists_evsel__exit() to allow filter
    persistence across TUI navigation while preventing memory leaks.
  - Add memset zeroing to free_popup_actions() to prevent cross-iteration
    stale action leakage.
  - Placed "Remove duplicated thread in popup_action" as the final patch
    in the series as requested.
