sqlite3 Rewritten in RiiR Rust crabcrabcrab

Finally, one of the best written software paired with one of the best writable programming language‽ Fearless and memory safe, since the uncountable amount of unsafe {} blocks makes you not care anymore.

Wait, what?

This is just the sqlite3 code passed throught the c2rust transpiler, along with some cleanup from me. I've found no way to hook it to sqlite3's testing harnesses yet so I doubt it's completely functional; but opening the shell seems to work.

I am suspicious that a lot of code under ifdefs or not is lost through the transpilation, because the binary size difference is substantial:

$ du -sh $(which sqlite3)
9.5M    /home/epilys/.local/bin/sqlite3
$ du -sh target/release/rsqlite3
5.1M    target/release/rsqlite3
