Previously the output was 0x41 or 0o101 or 0b1000001, now it is 41 or
101 or 1000001. We drop these prefixes, since they decrease the readability
of the PD output (especially when displayed in GUIs) and are not needed
anyway since the user knowingly selected the number format before running
the respective PD.

Assume that the initial pin state is 1/high for the RX and TX lines.
This fixes the decode when an LA triggers on e.g. TX=low (the first
sample would be low in that case, so the falling edge for the start bit
would be missed by the decoder).

This now makes the UART decoder suitable for use in GUIs.
This fixes bug #148.

The Python module name is determined by the directory name (e.g. dcf77),
the *.py file names in that directory don't matter and can be kept
consistent.

Thanks Iztok Jeras <iztok.jeras@gmail.com> for the report.

Ignore/skip identical samples in most (low-level) PDs, as we're usually
(but not necessarily always) only interested in pin changes.
This yields a significant performance improvement for the PDs.
The mechanism was already used in the 'i2s', 'jtag', and 'lpc' PDs, but not
yet in all supported low-level decoders. The following PDs now also use
this mechanism: 'dcf77', 'i2c', 'spi', 'uart', and 'usb_signalling'.
Thanks Lars-Peter Clausen <lars@metafoo.de> for bringing this to our
attention.

While this has a (small) performance penalty compared to using integers,
it has the advantage of not requiring the use of magic numbers which
need to be declared in both the UART decoder and all decoders which
stack on top of UART.

- List all API methods and metadata variables in all PDs to make things
easier and more consistent for new PD writers.
- Fix probe assignment in a few PDs.
- Raise exceptions upon invalid states of the PD state machines (bug).
