2013-09-14i2c: Drop unneeded 'addressing' option.Uwe Hermann
This (unimplemented so far) option is not needed at all, since the decoder will be able to detect 7/10 bit slave addresses automatically, the user doesn't have to specify slave address sizes.

2013-09-14i2c: Various fixes to make the PD suitable for GUIs.Uwe Hermann
The output format of the slave address is now a PD option. It can be "shifted" or "unshifted", i.e. bit 0 (which contains a read/write marker) is either shifted out or not, i.e., the slave address is displayed as 8bit or 7bit number (or 11bit/10bit number for 10bit slave addresses). Data bytes (not address bytes) are always shown as 8bit values, of course. Add annotation types for the individual I2C components such as start conditions, stop conditions, ACK/NACK, address read/writes, data read/writes and so on. This fixes bug #151.
2013-09-08i2c: Fix corner-case that can occur with LA triggers.Uwe Hermann
Until now the I2C PD was basically ignoring the very first sample, and using that as the initial 'oldscl'/'oldsda' value. However, if your logic analyzers trigger on, say, SDA=low that will result in a file where the first sample is really important since it is the one which the PD will need to know that there's a falling edge on SDA. Thus, assume both SCL and SDA are high/1 when the PD starts. This is a good assumption since both pins have pullups on them in practice and are thus high/1 when the bus is idle. Later on we might want to have config options to let the PD assume other states of SDA/SCL initially.

2012-11-24All PDs: Name the files pd.py consistently.Uwe Hermann
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.
