Summary0001442: undo/redo for channels add/remove is bugged
Description

Try to add new channel, then undo it and redo it. You will encounter some bugs.

Steps To Reproduce

a) assume that there is only one channel named "111"

  1. right click on channel header -> add channel -> AFTER this channel
  2. undo once
  3. redo once
  4. new channel did not return.

b) assume that there is only one channel named "111"

  1. right click on channel header -> add channel -> BEFORE this channel
  2. undo once
  3. redo once
  4. new channel will replace old channel "111".

c) assume that there is only one channel named "111"

  1. right click on channel "111" header -> add channel -> AFTER this channel
  2. right click on channel "111" header -> add channel -> BEFORE this channel
  3. undo once
  4. redo once
  5. one channel will return, but third one will be dropped at the same time.

I haven't tested this in 1.30.00.* (testing), but I can say that it works as intended on 1.29.*.*

Undo and Redo remove and re-add the channels as you would expect.

There are some optimizations in 1.30 which make it easier to update the UI for just a single channel if only that one channel was edited (e.g. channel name). It's probably related to these changes, I'll look into it.

There are some edge cases that also don't work properly in 1.29 due to similar fundamental issues. For example:

  1. Have a single channel with some data in it
  2. Duplicate it.
  3. Undo
  4. Redo and observe that the data from the second channel is gone.

Should be fixed in r14623 (and a fix in r14624 for OpenMPT 1.29).
