N_HTTP_RANGE	n_http_parse_range (const char value, size_t len, long long total, long long first, long long *last)
	interpret a single-range Range header for a body of total bytes
int	n_http_response_add_header (N_HTTP_RESP r, const char name, const char *value)
	add a header line after validating name and value
int	n_http_response_append (N_HTTP_RESP r, const void data, size_t len)
	append bytes to the memory body (drops a file body)
long long	n_http_response_body_length (const N_HTTP_RESP *r)
	body length the response declares, 0 for a bodiless status
int	n_http_response_file (N_HTTP_RESP *r, int fd, long long offset, long long length)
	use a file range as the body; the response owns fd from now on
void	n_http_response_free (N_HTTP_RESP **r)
	free a response (closing its file body) and set *r to NULL
const char *	n_http_response_get_header (const N_HTTP_RESP r, const char name)
	value of the first header of that name (ASCII case-insensitive)
int	n_http_response_head (const N_HTTP_RESP r, N_STR *out)
	append the status line and headers, through the blank line
N_HTTP_RESP *	n_http_response_new (int status)
	new response with a status, keep-alive off, HTTP/1.1
size_t	n_http_response_remove_header (N_HTTP_RESP r, const char name)
	remove every header of that name (ASCII case-insensitive)
int	n_http_response_set_connection (N_HTTP_RESP *r, int keep_alive, int version_minor, int head_only)
	connection handling for this response
int	n_http_response_set_header (N_HTTP_RESP r, const char name, const char *value)
	set a header: remove every header of that name, then add it
int	n_http_response_set_status (N_HTTP_RESP *r, int status)
	change the status code
int	n_http_response_write (const N_HTTP_RESP r, n_http_write_fn fn, void ctx)
	write the whole response (head, then body unless HEAD or bodiless)
const char *	n_http_status_reason (int status)
	reason phrase of a status code, a class phrase for an unlisted one
