Git fix all "missing" renames

To continue the previous epopee: we shall interactively detect all the occurrences of the missed renames in a given git repo, and let user choose if he wants to make a potential rename into real rename.

Git fix the "missed" rename

In git, there are no renames. It uses "heuristics" to detect files been deleted-and-added that are "actually" renamed. The "good practice" is to never mix these "renames" with file modifications, else git will loose the track of "renames" and thus history navigation for these files will become a serious pain. But sometimes you "forget" about these "great" practices. The script to fix an accidental loss of real rename below is to the resque.

WIN32_LEAN_AND_MEAN and DuckDB

This keeps striking me every other year when building something from sources.

Got a ton of windows.h-related errors when compiling C++ sources is a typical sign.

The correct way would be to define WIN32_LEAN_AND_MEAN when building:

git clone git@github.com:duckdb/duckdb.git --branch v0.8.1 --single-branch
cd duckdb
python scripts/amalgamation.py
md build
cd build
cmake -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE=Debug -DAMALGAMATION_BUILD=ON -D CMAKE_CXX_FLAGS="/D WIN32_LEAN_AND_MEAN" ..
cmake --build . --config Debug
