This adds functions to transform a Twisted request to the
`http::Request`, and then to send back an `http::Response` through it.
It also imports the SynapseError exception so that we can throw that
from Rust code directly
Example usage of this would be:
```rust
use crate::http::{http_request_from_twisted, http_response_to_twisted, HeaderMapPyExt};
fn handler(twisted_request: &PyAny) -> PyResult<()> {
let request = http_request_from_twisted(twisted_request)?;
let ua: headers::UserAgent = request.headers().typed_get_required()?;
if whatever {
return Err((crate::errors::SynapseError::new(
StatusCode::UNAUTHORIZED,
"Whatever".to_owned
"M_UNAUTHORIZED",
None,
None,
)));
}
let response = Response::new("hello".as_bytes());
http_response_to_twisted(twisted_request, response)?;
Ok(())
}
```
