This includes using a separate (but backward compatible) proto for the cc_analyzer since some of the fields/messages were removed in the new ide_query format. Tested the ide_query.go with the old and the new cc_analyzer to ensure backward compatibility. Change-Id: If149f5f9dd88a8f50c184274e8b258dfce117498

// Driver for c++ extractor. Operates in two modes:
|
|
// - DEPS, scans build graph for active files and reports targets that need to
|
|
// be build for analyzing that file.
|
|
// - INPUTS, scans the source code for active files and returns all the sources
|
|
// required for analyzing that file.
|
|
//
|
|
// Uses stdin/stdout to take in requests and provide responses.
