[Qemu-arm] [PATCH v2 1/2] BootLinuxConsoleTest: Let extract_from_deb han

From: Philippe Mathieu-Daudé
Subject: [Qemu-arm] [PATCH v2 1/2] BootLinuxConsoleTest: Let extract_from_deb handle various compressions
Date: Wed, 13 Mar 2019 00:45:40 +0100

Debian binary package format supports various compressions.

Per man deb(5):

    deb - Debian binary package format

    The third, last required member is named data.tar.  It contains the
    filesystem as a tar archive, either not compressed (supported since
    dpkg 1.10.24), or compressed with gzip (with .gz extension),
    xz (with .xz extension, supported since dpkg 1.15.6),
    bzip2 (with .bz2 extension, supported since dpkg 1.10.24) or
    lzma (with .lzma extension, supported since dpkg 1.13.25).

List the archive files to have the 3rd name with the correct extension.

The function avocado.utils.archive.extract() will handle the different
compression format for us.
