Rename 'probe' to 'channel' everywhere.
Variables of type 'struct srd_channel *' are consistently named 'pdch' to
make them easily distinguishable from libsigrok's 'struct sr_channel *'
variables that are consistently named 'ch'.

/**
* Send a chunk of logic sample data to a running decoder session.
*
- * If no probe map has been set up, the logic samples must be arranged
- * in probe order, in the least amount of space possible. The default
- * probe set consists of all required probes + all optional probes.
+ * If no channel map has been set up, the logic samples must be arranged
+ * in channel order, in the least amount of space possible. The default
+ * channel set consists of all required channels + all optional channels.
*
* The size of a sample in inbuf is the unit size passed to
- * srd_inst_probe_set_all(). If no probe map has been configured, it is
- * the minimum number of bytes needed to store the default probes.
+ * srd_inst_channel_set_all(). If no channel map has been configured, it is
+ * the minimum number of bytes needed to store the default channels.
*
* @param sess The session to use.
* @param start_samplenum The sample number of the first sample in this chunk.
