Stefan Hajnoczi 58a2e3f5c3 block: compile out assert_bdrv_graph_readable() by default ...

reader_count() is a performance bottleneck because the global
aio_context_list_lock mutex causes thread contention. Put this debugging
assertion behind a new ./configure --enable-debug-graph-lock option and
disable it by default.

The --enable-debug-graph-lock option is also enabled by the more general
--enable-debug option.
