applet.interface.jtag_svf: reset DUT if not reset explicitly.

applet.interface.jtag_probe: disallow pulse_tck() in Shift-XR.

This would interact badly with state transition on the last bit, and
is not allowed by e.g. SVF specification.

applet.interface.jtag_probe: raise exception on invalid state transitions.

Instead of asserting.

Replace inappropriate uses of bitarray with support.bits.

* Never trip up on endian="little" again.
* Never reverse bit literals compared to the datasheet again.
* Rely only on Python builtins and not C extensions.

A few cases (JESD3C fuses, PDI bitmaps) actually call for a bitarray,
so those are kept as-is.

support.logging: add dump_bin(), for dumping bits.

This method dumps bits from LSB to MSB, in logical order. This
notably does not match the literal order.

support.bitstruct: rework to use support.bits internally.

support.{bits→bitstruct}

Also rename Bitfield to bitstruct.

support.chunked_fifo: convert written data before using.

applet.interface.sbw_probe: remove unnecessary TMS setup delay.
