* New upstream release.debian/15+1533136590.3beb971-1
- debian/patches/second-stage-path: dropped; the default loader path now
includes an arch suffix.
- debian/patches/sbsigntool-no-pesign: dropped; no longer needed.
* Drop remaining patches that were not being applied.
* Sync packaging from Ubuntu:
- debian/copyright: Update upstream source location.
- debian/control: add a Build-Depends on libelf-dev.
- Enable arm64 build.
- debian/patches/fixup_git.patch: don't run git in clean; we're not
really in a git tree.
- debian/rules, debian/shim.install: use the upstream install target as
intended, and move files to the target directory using dh_install.
- define RELEASE and COMMIT_ID for the snapshot.
- Set ENABLE_HTTPBOOT to enable the HTTP Boot feature.
- Update dh_auto_build/dh_auto_clean/dh_auto_install for new upstream
options: set MAKELEVEL.
- Define an EFI_ARCH variable, and use that for paths to shim. This
makes it possible to build a shim for other architectures than amd64.
- Set EFIDIR=$distro for dh_auto_install; that will let files be installed
in the "right" final directories, and makes boot.csv for us.
- Set ENABLE_SHIM_CERT, to keep using ephemeral self-signed certs built
at compile-time for MokManager and fallback.
- Set ENABLE_SBSIGN, to use sbsign instead of pesign for signing fallback
and MokManager.
