FeRD (Frank Dana) 2edf2a9b34 Update to libarchive 3.4.0
* New upstream release. Adds RAR5 and ZIPX support (readonly),
  64-bit ar, improved extraction and file-attribute support.
* Switch to HTTPS URLs
* Drop upstreamed security patches
* Add patch (submitted upstream) to fix zstd test when built with
  different libzstd releases
* Remove BuildRequires: on lzo-devel, as the release notes for 3.3.x
  included a notice regarding licensing issues when linking with liblzo.

Subject: [PATCH] test_write_filter_zstd: size @ lvl=20 < default < lvl=1
Raise compression on the second test to level=20, and perform a
third at level=1. Expect the output archive sizes to line up
based on compression level. Reduces test susceptibility to small
output size variations from different libzstd releases.
