Release 3.49.12

Roll up 25 commits since 3.49.11 (July 5): security fixes in the
network-facing parsers (remote stack overflow and uninitialized read in
Content-Type/-Encoding handling, fuzzer-found over-reads in the filter,
URL and IDNA parsers, cache-index bounds, filter-pattern backtracking,
world-readable cookies.txt), crawl-correctness fixes (double-encoded UTF-8
links, gzip-mislabeled bodies, cache reconcile/corruption handling,
orphaned .delayed placeholders), the new --why filter diagnostic, and
build hardening (_FORTIFY_SOURCE, -fstack-protector-strong).

VERSION_INFO 3:3:0 -> 3:4:0: httrackp tail-appends why_url, no layout or
exported-signature break, so soname stays libhttrack.so.3 (revision bump).
