…bz2 (pythonGH-160315) A damaged .xz or bzip2 stream that followed another stream was taken for trailing data and silently ignored. Leftover data that starts with the stream magic is now treated as a stream, as gzip does. ANT-2026-3TVAVL5A (cherry picked from commit a4f8047)

(cherry picked from commit a4f8047)
Manual backport notes (3.15): the automated backport conflicted only in
Doc/library/bz2.rst. A second commit drops theversionchangednotesthe original added to
Doc/library/bz2.rstandDoc/library/lzma.rst,as bugfix-level behavior changes are not recorded that way; they are
being removed on main as well. test_bz2, test_lzma and the other
compression-related tests pass on 3.15.
