Currently it is just a different implementation of the same use cases.
However, logic for processing the gcov output moves from CTest to CDash.
The ctest_submit(CDASH_UPLOAD) command doesn't just upload files, it
contacts a new CDash API to send files with (json) metadata.  Over
time this will allow more coverage types to be added without having to
modify CTest, and CDash will be able to process tool-specific coverage
output and display it in a custom manner.  Previously CTest had to
mangle the output of various tools into the Coverage.xml format that
CDash expects.
