fix(db): upgrade to libmdbx 0.12.2;

[galaio]

This pr tries to fix the compile error described in https://github.com/paradigmxyz/reth/discussions/368. I had tried some previous libmdbx versions, and v0.12.1 is not work in x86_64, reth should use the latest version, it works.

I upgrade libmdbx version steps as below:

1. Visit release page libmdbx 0.12.2;
2. Download libmdbx-amalgamated-0_12_2.zip;
3. Unzip source code, and replace in path crates/storage/libmdbx-rs/mdbx-sys/libmdbx;
4. Test it, cargo clean & cargo test --all;

Great you found the fix! but we need to follow the procedure from here: https://github.com/paradigmxyz/reth/tree/main/crates/storage/libmdbx-rs (I think it trims down some files)

Appreciate you taking the time.

Let's not rush with merging also - would like to understand what changed / why this if a fix, and if there's any license issues.

Hi @rakita , I reproduce libmdbx code by the below steps, it gets the same files, with no change to release v0.12.2.

cd crates/storage/libmdbx-rs
git clone https://gitflic.ru/project/erthink/libmdbx.git ~/libmdbx --branch v0.12.2
make -C ~/libmdbx dist
rm -rf mdbx-sys/libmdbx
cp -R ~/libmdbx/dist mdbx-sys/libmdbx
git add mdbx-sys/libmdbx

This helped resolve many of the errors I had trying to build on Windows 10, but I am left with two involving afl.rs. They are the exact same as reported in this open issue with an older version: https://github.com/rust-fuzz/afl.rs/issues/186 .

Yikes - but yeah this is expected given we use a c library and try to go cross platform. Appreciate the patience until we dig into this and eventually switch to a pure Rust db like https://github.com/cberner/redb.
