This is a copy of qtdeclarative/src/quick/util/qminimalflatset_p.h as
of qtdeclarative/1e6cb2462ee87476a5eab7c71735c001a46c7b55, with the
following changes:
- Use a different header guard name. The header guard name is being
changed in qtdeclarative in parallel, but don't let there be a
window in which there might be a conflict.
- Add a type alias for QVarLengthArray-backed QMinimalFlatSet.
- Remove the qtquickglobal.h header.
- Adjust the introducing comment to the new home.
I've seen several use-cases for this in QtBase the last few days, so
it's time to move it into a more central place and get more users.
