Carl Dong 96cc6bb04f guix/prelude: Override VERSION with FORCE_VERSION 
Previously, if the builder exported $VERSION in their environment (as
past Gitian-building docs told them to), but their HEAD does not
actually point to v$VERSION, their build outputs will differ from those
of other builders.

This is because the contrib/guix/guix-* scripts only ever act on the
current git worktree, and does not try to check out $VERSION if $VERSION
is set in the environment.

Setting $VERSION only makes the scripts pretend like the current
worktree is $VERSION.

This problem was seen in jonatack's attestation for all.SHA256SUMS,
where only his bitcoin-22.0rc3-osx-signed.dmg differed from everyone
else's.

Here is my deduced sequence of events:

1. Aug 27th: He guix-builds 22.0rc3 and uploads his attestations up to
   guix.sigs

2. Aug 30th, sometime after POSIX time 1630310848: he pulls the latest
   changes from master in the same worktree where he guix-built 22.0rc3
   and ends up at 7be143a960

3. Aug 30th, sometime before POSIX time 1630315907: With his worktree
   still on 7be143a960, he guix-codesigns. Normally, this would result
   in outputs going in guix-build-7be143a960e2, but he had
   VERSION=22.0rc3 in his environment, so the guix-* scripts pretended
   like he was building 22.0rc3, and used 22.0rc3's guix-build directory
   to locate un-codesigned outputs and dump codesigned ones.

   However, our SOURCE_DATE_EPOCH defaults to the POSIX time of HEAD
   (7be143a960), which made all timestamps in the resulting codesigned
   DMG 1630310848, 7be143a960e2's POSIX timestamp. This differs from the
   POSIX timestamp of 22.0rc3, which is 1630348517. Note that the
   windows codesigning procedure does not consider SOURCE_DATE_EPOCH.

We resolve this by only allowing VERSION overrides via the FORCE_VERSION
environment variable.

Repository Tools

Developer tools

Specific tools for developers working on this repository. Additional tools, including the github-merge.py script, are available in the maintainer-tools repository.

Verify-Commits

Tool to verify that every merge commit was signed by a developer using the github-merge.py script.

Linearize

Construct a linear, no-fork, best version of the blockchain.

Qos

A Linux bash script that will set up traffic control (tc) to limit the outgoing bandwidth for connections to the Bitcoin network. This means one can have an always-on bitcoind instance running, and another local bitcoind/bitcoin-qt instance which connects to this node and receives blocks from it.

Seeds

Utility to generate the pnSeed[] array that is compiled into the client.

Build Tools and Keys

Packaging

The Debian subfolder contains the copyright file.

All other packaging related files can be found in the bitcoin-core/packaging repository.

Gitian-descriptors

Files used during the gitian build process. For more information about gitian, see the the Bitcoin Core documentation repository.

Builder keys

PGP keys used for signing Bitcoin Core release results.

MacDeploy

Scripts and notes for Mac builds.

Gitian-build
