Move initialization code of protocol decoders from the constructor to a
new reset() helper method. The libsigrokdecode backend could run this
method several times to clear the decoder's internal state, before new
data from another acquisition gets fed to decode() calls.

According to the USB 2.0 spec, 8.5.3.4, a protocol stall condition lasts
until the next SETUP transfer. On reception of the SETUP, adjust the end
sample accordingly, and flush the previous CONTROL transfer.

This is not really relevant for stacked PDs currently (they can be used
unmodified with either PDv2 or PDv3 low-level decoders), but it'll allow
us to drop PDv2 support completely.

Remove the FSF postal address as it might change (it did in the past).
Reference the gnu.org website instead which is more stable.

The libsigrokdecode backend now passes metadata (e.g. samplerate) to all
PDs, stacked and non-stacked (see bug #664), so this interim solution is no
longer needed.

This is more consistent with annotation syntax and looks slightly
better in most cases.

If a device or host did not receive a handshake 18 bit times after the
EOP, there was a transmission error and the host may repeat the
transmission

The new decoder stacks on top of the usb_packet PD. It adds one new
annotation row, and is able to save the decoded data as PCAP trace.
It has been successfully tested against all traces in sigrok-dumps and
some more traces.
