When building with Ant, instead of Moxie, JaCoCo is not included in the
classpath. So explicitly initialise the full `jacocoant.jar` from the
`.moxie` repository.

For this we had to switch the dependency to use the `nodeps` jar which
includes all dependencies.

This can be uploaded to coverage services like Coveralls etc.

Add some guidelines for contributors regarding pull requests,
commits and code conventions.

Add service scripts for FreeBSD

Also: release notes.

Update the service scripts to use `-cp` and specify the GitBlitServer
class, instead of the `-jar` parameter.

Fixes #1333

While most systems will not need the class path passed to the JVM with
the `-cp` parameter to be in quotes, apparently some exist where that
will not work without the quotes, e.g. FreeBSD.
So always use quotes for the class path in all scripts.

Issue #1333

This is needed for the scripts to work in Alpine Linux, which
comes with a Bourne shell.

Zero out the password to remove it from memory after use.
This is only a first step, implementing it for one method:
`AuthenticationManager.authenticate(String, char[], String)`.

The upgrade of a MD5 stored password hash to a PBKDF password hash
destroys the stored password. The has check zeroes out the password that
is tested, so that the new hash is built over the zeroed out value.

This fix prevents that an also adds a check to the test.

Fixes #1335

The Eclipse maven repositories changed to only allow HTTPS and not
serve HTTP anymore. HTTP will redirect to HTTPS, which moxie does
not handle well and fails.

So the registered Eclipse repositories are changed to 'https://'
transport.

Fixes #1334

Set the ignored branches pattern to `release*` for the normal ci workflow.

If requested, by setting a file name in the `versionInfo`
property, store release version and tag in a file, for
other scripts and programs to pick up.

Use the same templates as in `buildSite` to generate the change log
in the built-in documentation.

Moxie does have these defined by default, but with transport HTTP.
Since January 2020, Maven Central only accepts HTTPS, no HTTP
anymore. So we add them here explicitly, with `https://`.
We add it to the `build.moxie` file, instead of keeping it in a
local `settings.moxie`, so that a CI server can immediately use it.

Since Google Plus doesn't exist any more...

Add pages for `fail2ban` and GFS to the `generateDocs` target, so that
they also show up in the documentation on GO etc.
Also adjust the links to issues and commits.

Add the replacement of the download base URL.

Google Plus is gone, so linking to it makes no sense anymore.

Add property `release.tag` to keep a generally available property.
The `project.tag` was getting used in many places, so I need a global
definition for it. The property `project.tag`, defined in the target
`tagRelease` could not be reused, since when that target runs, the
version is still a SNAPSHOT version. (And properties don't get
re-assigned.) So instead a new property `release.tag` is defined,
just like `release.name`, which can be only used sensible in a
release stage, i.e. after `tagRelease` ran.

The site was generated, but updating the gh-pages branch was included
in the `publishSite` target. So a new target is added and called,
`updateSite`.

The major change is switching from `publishBinaries`, which still
exists and uploads to Bintray, to `releaseBinaries`, which creates
a draft release on GitHub and uploads the binaries.

Another change is some reordering. Now first the binaries are
uploaded, the maven artifacts pubished and the tag and site pages
pushed. Then the GitHub release is made public.
Only after that is the minor version bumped and pushed.

The whole script could use some error checking and stoping when
things go wrong, instead of blindly continuing.

A minor change, and temporary, is that we need and check for Ant 1.9,
as we still build with Java 7.

Add Ant tasks and macros to deploy binaries to GitHub,
using GitHub's releases.

Adds an Awk script to extract GH flavoured markdown release notes
from the release.moxie file.

Adds `ok.sh` to the repository so that it is readily available.
This is a Bourne shell GitHub API client, used to create a release
on GitHub and upload the binaries.

Now we can also build on GitHub

ci ignore

Add a job to run a build with Java 7.
The job currently only runs on Linux.
In order to run on Java 7, an old Ant version is downloaded and
installed. We use moxie+ant for this, so we build with moxie.

Currently that is Ubuntu 18.04 and Windows Server 2019.
https://help.github.com/en/actions/automating-your-workflow-with-github-actions/virtual-environments-for-github-hosted-runners

We cannot build with Ant on GitHub since the provided Ant
version does not run on Java 7.

I actually don't know if it is needed for the manager and fedclient,
but right now I'm going with better safe than sorry.
