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.
