Apache 2.0 agent supports additional HTTP methods for a Subversion repository (6647805)

The Apache 2.0 agent now recognizes these additional methods: VERSION_CONTROL, CHECKOUT, UNCHECKOUT, CHECKIN, UPDATE, LABEL, REPORT, MKWORKSPACE, MKACTIVITY, BASELINE_CONTROL, and MERGE. These methods are used for WebDAV versioning (RFC 3253) and specifically for a Subversion repository.
