This commit moves the classes from the o.s.ws.transport.http and
o.s.ws.transport.support packages from spring-ws-support to
spring-ws-core. It turns out these classes don't bring extra
dependencies, which make the move quite straightforward.
Closes gh-1202
This commit updates the Gradle build to run checkstyle against the main
sources. Checks for tests, as well as certain rules, are disabled as a
first step.
