The git download helper is getting a bit more complex. Fixing it in the
Makefile when it breaks (like the recent breakage with a non-existing
sha1-cset) proves to be challenging, to say the least.
Move it into a shell script in support/download/git, which will make
it much easier to read, maintain, fix and enhance in the future.

Maintaining the download helpers in the Makefile has proved to be a bit
complex, so move it to a shell script.

To: buildroot
From: "Yann E. MORIN" <yann.morin.1998@free.fr>
DL_DIR can be a very precious place for some users: they use it to store
all the downloaded archives to share across all their Buildroot (and
maybe non-Buildroot) builds.
We do not want to trash this location with our temporary downloads (e.g.
git, Hg, svn, cvs repository clones/checkouts, or wget, bzr tep tarballs).
Turns out that we already have some kind of scratchpad, the BUILD_DIR.
Although it is not really a disposable location, that's the best we have
so far.
Also, we create the temporary tarballs with mktemp using the final tarrball,
as template, since we want the temporary to be on the same filesystem as
the final location, so the 'mv' is just a plain, atomic rename(2), and we
are not left with a half-copied file as the final location.
Using mktemp ensures all temp file names are unique, so it allows for
parallel downloads from different build dirs at the same time, without
cloberring each downloads.
Note: we're using neither ${TMP} nor ${TMPDIR} since they are shared
locations, sometime with little place (eg. tmpfs), and some of the
repositories we clone/checkout can be very big.

Changes v5 -> v6:
- ensure we can do parallel downloads from multiple build-dirs (Thomas)
Changes v4 -> v5
- explain why we create the temp files where we create them (Arnout)
Changes v3 -> v4:
- remove spurious bump in package/fis (Samuel)

As noticed by Thomas on IRC: leftovers from a previous attempt.
Fixed locally, waiting for more review before re-spinning.

To: buildroot
From: "Yann E. MORIN" <yann.morin.1998@free.fr>
Some of the packages that Buildroot might build are sensitive packages,
related to security: openssl, dropbear, ca-certificates...
Some of those packages are downloaded over plain http, because there is
no way to get them over a secure channel, such as https.
In these dark times of pervasive surveillance, the potential for harm that
a tampered-with package could generate, we may want to check the integrity
of those sensitive packages.
So, each package may now provide a list of hashes for all files that needs
to be downloaded, and Buildroot will just fail if any downloaded file does
not match its known hash, in which case it is removed.
Hashes can be any of the md5, sha1 or sha2 variants, and will be checked
even if the file was pre-downloaded.

Changes v4 -> v5:
- fix detection of comments and empty lines
---
Note: this is not a bullet-proof solution, since Buildroot may itself be
compromised. But since we do sign our releases, then we secure the list of
hashes at the same time. Only random snapshots from the repository may be
at risk of tampering, although this is highly doubtfull, given how git
stores its data.

Although md5 is, for legacy reasons, a supported hash type,
it is not documented on purpose, since it is now known to
be weak.

+The +.hash+ file
+~~~~~~~~~~~~~~~~
+[[adding-packages-hash]]
+
+Optionally, you can add a third file, named +libfoo.hash+, that contains
+the hashes of the downloaded files for the +libfoo+ package.
+
+The hashes stored in that file are used to validate the integrity of the
+downloaded files.
+
+The format of this file is one line for each file for which to check the
+hash, each line being space-separated, with these three fields:
+
+* the type of hash, one of:
+** +sha1+, +sha224+, +sha256+, +sha384+, +sha512+
+* the hash of the file:
+** for +sha1+, 40 hexadecimal characters
+** for +sha224+, 56 hexadecimal characters
+** for +sha256+, 64 hexadecimal characters
+** for +sha384+, 96 hexadecimal characters
+** for +sha512+, 128 hexadecimal characters
+* the name of the file, without any directory component
+
+Lines starting with a +#+ sign are considered comments, and ignored. Empty
+lines are ignored.
+
+There can be more than one hash for a single file, each on its own line. In
+this case, all hashes must match.
+
+Ideally, the hashes stored in this file should match the hashes published by
+upstream, e.g. on their website, in the e-mail announcement... If upstream
+provides more than one type of hash (say, +sha1+ and +sha512+), then it is
+best to add all those hashes in the +.hash+ file. If upstream does not
+provide any hash, then compute at least one yourself, and mention this in a
+comment line above the hashes.
+
+*Note:* the number of spaces does not matter, so one can use spaces to
+properly align the different fields.
+
+The example below defines a +sha1+ and a +sha256+ published by upstream for
+the main +libfoo-1.2.3.tar.bz2+ tarball, plus two locally-computed hashes,
+a +sha256+ for a downloaded patch, and a +sha1+ for a downloaded binary blob:
+
+----
+# Hashes from: http://www.foosoftware.org/download/libfoo-1.2.3.tar.bz2.{sha1,sha256}:
+sha1 486fb55c3efa71148fe07895fd713ea3a5ae343a libfoo-1.2.3.tar.bz2
+sha256 efc8103cc3bcb06bda6a781532d12701eb081ad83e8f90004b39ab81b65d4369 libfoo-1.2.3.tar.bz2
+
+# No upstream hashes for the following:
+sha256 ff52101fb90bbfc3fe9475e425688c660f46216d7e751c4bbdb1dc85cdccacb9 libfoo-fix-blabla.patch
+sha1 2d608f3c318c6b7557d551a5a09314f03452f1a1 libfoo-data.bin
+----
+
+If the +.hash+ file is present, and it contains one or more hashes for a
+downloaded file, the hash(es) computed by Buildroot (after download) must
+match the hash(es) stored in the +.hash+ file. If one or more hashes do
+not match, Buildroot considers this an error, deletes the downloaded file,
+and aborts.
+
+If the +.hash+ file is present, but it does not contain a hash for a
+downloaded file, no check is done for that file. If you set the
+environment variable +BR2_ENFORCE_CHECK_HASH+ to a non-empty value, and
+there is no hash for a downloaded file, Buildroot considers this an
+error, deletes the downloaded file, and aborts.
+
+If the +.hash+ file is missing, then no check is done at all.

ca-certificates contains sensitive security-related information,
and we want to ensure the archive that we download has not been
compromised.
Add the sha1 and sha256 hashes from Debian's packaging.
