applet.benchmark: hint reads to use total length.

When making very large reads, it is often possible to either predict
the total length exactly (e.g. the shugart-floppy applet) or to use
a "sufficiently large" buffer (e.g. the lpc applet). Thus, it seems
that a benchmark should not use an artificially small hint.

firmware: add Device Qualifier request.

Necessary for USB compliance.

access.direct.demultiplexer: use ChunkedFIFO.

This significantly improves `benchmark sink`:

(before)
I: glasgow.applet.benchmark: mode sink: 1.454 MiB/s
(after)
I: glasgow.applet.benchmark: mode sink: 16.420 MiB/s

On my system the sink rate asymptotically approaches around 20 MiB/s.
16 MiB/s is an approx 10x improvement, and uses 1/32 of the Linux
usbdevfs memory limit, which is acceptable for now.

Fixes #79.

support.chunked_fifo: fix bool() with partial reads.

support.chunked_fifo: implement.

Required for #79.

support.pyrepl: do not crash if _ is not defined.

This happens e.g. if the first entered statement is `import foo`.

internal_test: remove.

Outdated, bitrotted, not very useful, and confusing since it shows
up in --help.
