Has package.cmake copy docs into a top-level html/ directory. Sets up Travis to push the html/ directory to the dynamorio_docs repository. The x86 build sets DEPLOY_DOCS which runsuite_wrapper turns into a copy_docs parameter to package.cmake and which is used as a condition for the Travis deployment.
Travis will not do deployments on pull requests so this can only be tested once it is merged into master.
Fixes #3194 (closed)
