[PATCH v4 0/8] iio: core: New macros and making use of them

Added new macros to overflow.h and reuse it in IIO. For the sake of examples
a few more places were updated (requested by Kees). In case maintainers are okay,
tags will be appreciated.

v4:
- dropped applied patches
- refactored macros and code to make them simpler (Jonathan)
- moved (renamed) macros to overflow.h

v3: https://lore.kernel.org/r/20230724110204.46285-1-andriy.shevchenko@xxxxxxxxxxxxxxx
- dropped applied patches
- use switch-case for the supported clocks (Jonathan)                                                            - redone opaque_struct_size() to be simpler (Uwe)
- dropped wrong hunk for krealloc_array() conversion (Jonathan)                                                  - dropped initcall move (Jonathan)

v2:
- sprintf() --> sysfs_emit() (Nuno)
