release: Bump for 1.4 release cycle.

This marks the start of a new release process as compared to previous
releases.

Instead of bumping the version just before a release and releasing from
the master branch, as has been done up to this point, the minor (or
major when necessary) will now be bumped on the master branch at the
beginning of a release cycle.  In addition, the pre-release portion of
the semantic version is now the string "pre" to help make it more
obvious that the master branch represents a pre-release build of work
leading up to the next release.

When a new release is prepared, a new release branch will be created
that has a naming scheme of "release-vX.Y", where X is the major and Y
is the minor.  Any additional commits needed to prepare the release
leading up to a release candidate will be cherry-picked to the release
branch, and all tags for releases and release candidates will be created
against that.

This implies that should any additional patch releases be necessary, the
relevant commits will also be cherry-picked to the release branch as
needed, followed by a new release candidate for the patch release and
the eventual patch release.
