Move audioDB::query over to audioDB.cpp At the same time, remove all the abstraction violations in audioDB::query, which came in two flavours: use of dbH->numFiles, which is dealt with by getting the database status instead (and is eventually unnecessary, being only needed now because reporters are implemented in terms of vectors indexed by ID), and use of fileTable in reporter's report functions (dealt with by passing in the adb instead). To actually implement reporting as of now, we continue to use stuff from audioDB-internals.h; maybe someday we will be clean and shiny.
