* python3.8: bulk removal of now obsolete "_python38" packages.
Done via scripting. No functional change intended or expected.
Some manual tweaks will follow.
* python3.8: further manual tweaks after bulk-3.8-removal.
Unlike the previous commit with automated changes,
I've tested builds for *these* recipes in beta4 64 bits.
- Switch to "any" arch (as this is pure Python code).
- Added support for Python 3.10.
- Added bash completion file for the default "cmd:tqdm".
- Install the man page.
