This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener).

Closes gh-22669

Issue: SPR-12766

This commit eliminates the 'integration-tests' subproject in favor of
managing these sources under the root project's own 'src' directory.

This helps to avoid special-case handling for integration-tests in the
Gradle build, e.g. avoiding publication of jars to Artifactory /
Maven Central.

It is also semantically more correct. This is not a Spring Framework
subproject so much as it is a collection of integration tests that
span functionality across many subprojects. In this way, it makes
sense to place them directly under the root project.

Issue: SPR-8116

Branch in question is 'env' branch from git://git.springsource.org/sandbox/cbeams.git; merged into
git-svn repository with:

    git merge -s recursive -Xtheirs --no-commit env

No merge conflicts, but did need to

    git rm spring-build

prior to committing.

With this change, Spring 3.1.0 development is now happening on SVN
trunk. Further commits to the 3.0.x line will happen in an as-yet
uncreated SVN branch.  3.1.0 snapshots will be available
per the usual nightly CI build from trunk.
