Konstantin Shabanov	5534eb93c6	Improve wasm32-wasi support ... [Starting from 3.41.0 SQLite has wasm32-wasi support out of the box.][0] - Set `-DSQLITE_THREADSAFE=0`. Fixes: ``` $ wasmtime target/wasm32-wasi/release/examples/persons.wasm Error: failed to run main module `target/wasm32-wasi/release/examples/persons.wasm` Caused by: 0: failed to instantiate "target/wasm32-wasi/release/examples/persons.wasm" 1: unknown import: `env::pthread_mutexattr_init` has not been defined ``` - Drop `-DSQLITE_OS_OTHER`. Fixes: ``` $ wasmtime target/wasm32-wasi/release/examples/persons.wasm Error: failed to run main module `target/wasm32-wasi/release/examples/persons.wasm` Caused by: 0: failed to instantiate "target/wasm32-wasi/release/examples/persons.wasm" 1: unknown import: `env::sqlite3_os_init` has not been defined ``` - [Add wasi specific build flags][1] - Add basic example - Also, add instructions how to run it against wasm32-wasi. Using of file databases is also working, though `--mapdir` arg should be provided to `wasmtime run`.
