Go bindings to SQLite using Wazero

⚠️ DO NOT USE with data you care about. ⚠️

This is very much a WIP.

Roadmap:

• build SQLite using zig cc --target=wasm32-wasi
• :memory: databases
• use test_demovfs.c for file databases
• come up with a simple, nice API:
  • idiomatic Go, close to the C SQLite API:
    • github.com/bvinc/go-sqlite-lite
    • github.com/crawshaw/sqlite
    • github.com/zombiezen/go-sqlite
    • github.com/cvilsmeier/sqinn-go
  • database/sql drivers can come later, if ever
• implement own VFS to sidestep WASI syscalls:
  • locking will be a pain point:
    • WASM has no threads
    • concurrency is achieved by instantiating the module repeatedly
    • file access needs to be synchronized, both in-process and out-of-process
    • out-of-process should be compatible with SQLite on Windows/Unix
• benchmark to see if this is useful at all:
  • github.com/cvilsmeier/sqinn-go
  • github.com/bvinc/go-sqlite-lite
  • github.com/mattn/go-sqlite3
  • modernc.org/sqlite

Random TODO list:

• optimize small allocations that last a single function call;
• …
