Bug 573712: Reorganize external tools detection code
The code was not very extensible and the main purpose of the bug is to add additional detectors. This first commit refactors the code to make that easier, and to provide a platform for what could become an extension point. Change-Id: I5ce514eda11f2573098d6e16663e324954da961b
