Is there a way to get the raw request from the client in a handler?

For HTTP/1.x (and HTTP/0.9), a reference to the request line is 
explicitly saved in the r->request_line field when parsing a request, 
see ngx_http_process_request_line() in src/http/ngx_http_request.c.

For HTTP/2, it is reconstructed.  See ngx_http_v2_construct_request_line() 
in src/http/v2/ngx_http_v2.c.
