Subject: [PATCH 1/9] u-boot-stable-src-release: follow u-boot and linux-libre
 naming conventions

Many people using FSDG compliant distributions or wanting to use one
are already familiar with linux-libre. This change renames the
resulting tarball to u-boot-libre to make it easier for people to
understand the goal of this tarball.

In addition we also rename the version from v2021.07 (which is the git
tag corresponding to the release) to 2021.07 as u-boot upstream
tarballs use that.

The revision wasn't bumped as we didn't have any releases of
u-boot-libre yet.

Subject: [PATCH 2/9] u-boot-stable-src-release: rename to u-boot-libre

If the script is named u-boot-stable-src-release and that users see an
u-boot-libre tarball they will not make the link between both unless
we rename the script.

Subject: [PATCH 4/9] download: Add --help in the individual download scripts

This doesn't change the existing usage of the scripts:
- For the Coreboot script, before this change, all arguments that were
  passed were considered as board to download the Coreboot source code
  for.

  Here we added the '--help' and '--list-boards' arguments, so it
  should not be an issue as it is extremely unlikely that a board
  would be called '--help' or '--list-boards'.

- All the other scripts don't use any arguments so passing --help
  should not conflict with the existing usage.
