//
// It checks the following conditions
// - the thread is allocated or not (by itself or one of its buddies). If it is it grabs the thread pointer.
// - the requested channel is the first (0) or the following
//
// There are two possible working modes:
// - Single Input (SI) with only one channel streaming. This HAS to be channel 0.
// - Multiple Input (MI) with two or more channels. It MUST be in this configuration if any channel other than 0
// is used irrespective of what you actually do with samples coming from ignored channels.
// For example When we will run with only channel 2 streaming from the client perspective the channels 0 and 1 will actually
// be enabled and streaming but its samples will just be disregarded.
// This means that all channels up to the highest in index being used are activated.
//
// It manages the transition form SI where only one channel (the first or channel 0) should be running to the
// Multiple Input (MI) if the requested channel is 1 or more. More generally it checks if the requested channel is within the current
// channel range allocated in the thread or past it. To perform the transition it stops the thread, deletes it and creates a new one.
// It marks the thread as needing start.
//
// If the requested channel is within the thread channel range (this thread being already allocated) it simply adds its FIFO reference
// so that the samples are fed to the FIFO and leaves the thread unchanged (no stop, no delete/new)
//
// If there is no thread allocated it creates a new one with a number of channels that fits the requested channel. That is
// 1 if channel 0 is requested (SI mode) and 3 if channel 2 is requested (MI mode). It marks the thread as needing start.
//
// Eventually it registers the FIFO in the thread. If the thread has to be started it enables the channels up to the number of channels
// allocated in the thread and starts the thread.
//
// Note: this is quite similar to the BladeRF2 start handling. The main difference is that the channel allocation (enabling) process is
// done in the thread object.
