common library common
Exports common interfaces that are implemented by both the dart:ffi and
the dart:js WASM version of this library.

- Describes how many arguments an application-defined sql function can take.
- BaseVfsFile common
- A VirtualFileSystemFile base class that implements xRead to zero-fill the buffer in case of short reads.
