Some download-related changes (branch yem/check-downloads)

From: "Yann E. MORIN" yann.morin.1998 [ at ] free.fr

Hello All!

This series contains those download-related changes:

- Patches 1..2 : preparatory patches for upcoming helper scripts and
hash checks

- Patches 3..8 : move download helpers to shell scripts, one
such script for each download helper

- Patch 9 : don't use DL_DIR as scratchpad for temporary VCS
checkouts, since DL_DIR is a precious location

- Patches 10..11: check hashes of downloaded files, to ensure the
files are genuine (with doc)

- Patch 12 : add hashes for ca-certificates

Changes v6 -> v7:
- use single-line title in manual (Samuel)
- use leftover cruft in bzr helper (Thomas)

Changes v5 -> v6:
- ensure we can run multiple parallel downloads from different build
dirs with the same BR2_DL_DIR (Thomas)
- also convert bzr
- fix for stray failed downloads

Changes v4 -> v5:
- update ca-certificates hashes after version bump
- fix detection of comments and empty lines in .hash file
- rebase on top of master

Changes v3 -> v4:
- enhance the manual, typoes (Gustavo, Samuel, Thomas DS)
- remove spurious test bump on package/fis (Samuel)

Changes v2 -> v3:
- avoid partial downloads (Thomas DS)
- store hash-type in .hash file (Gustavo)
- typoes (Samuel, Gustavo)
- add possibility to treat missing hashes as an error

Changes v1 -> v2:
- don't do any behavioural change when switching to shell scripts,
just reproduce exactly what was in the Makefile (Luca, Arnout)
- support more than one hash algorithm (Arnout, Gustavo)
- typoes (Luca, Baruch)

Regards,
Yann E. MORIN.
