Fix badly formatted changelog line

(Doesn't interfere with build, but lintian complains.)
Update R bindings
Add Conflicts against packages we bundle with dx-toolkit
Allow Ubuntu 14.04 dx-java-bindings to run against openjdk 7

(also cull build-depends that were only needed for EOL'd Ubuntu
releases)
Make dxpy.dxlink a no-op if given a link
Return result of execution in entry point decorator
Add bindings to project-xxxx/updateSponsorship method

Add R doc file that was missing from f13c95d
Update NAMESPACE too following f13c95d
Remove obsolete Javascript bindings

Summary:
These appear to not have received any substantive updates in over 2
years, and I don't know of anyone using them.

Test Plan: Monitor all toolkit integration tests. Built Debian package by hand locally.

Add link to dx-javascript-toolkit
Changelog and version updates for v0.118.0
PTFM-13157 First file download request blocks all subsequent requests

Summary:
If running on a worker, wait for the first file download chunk to come
back before issuing any more requests. This ensures that the backend can serve
cached data for the subsequent requests, instead of having all of the first
DXFILE_HTTP_THREADS requests simultaneously hit a cold cache.

Test Plan: verified that cache misses are reduced with the new client
