Improve bfCheckJavaPath performance testing

This commit should fix instabilites in the daily build of TestCheckJavaPath.
Successive calls to bfCheckJavaPath are not treated as independent. More
precisely, performance is only assessed for the third call and onwards.
Eclipse: ignore gmaven

There is no connector or simple lifecycle mapping for the gmaven plugin
execution, and it does not seem to be necessary for developing code in
Eclipse, so configuration was added to the top-level pom.xml for m2e to
ignore gmaven.
cpp: Move cmake project root to top level

Moving the toplevel CMakeLists.txt to the project root permits the
project root to be used by cmake directly.  This permits proper
paths to docs, components, etc. to be used.
cpp: Fix comments and indentation
test-build: cpp builds using project root
cpp: Update README to use project root
