Description:
------------
`sapi_cgi_send_headers()` (in both `sapi/fpm/fpm/fpm_main.c` and `sapi/cgi/cgi_main.c`) will truncate HTTP Status headers larger than `SAPI_CGI_MAX_HEADER_LENGTH` in the following cases, potentially causing the trailing CR LF to be stripped.

	`len = slprintf(buf, SAPI_CGI_MAX_HEADER_LENGTH, "%s\r\n", SG(sapi_headers).http_status_line);`
	`len = slprintf(buf, sizeof(buf), "Status:%s\r\n", s);`
	`len = slprintf(buf, sizeof(buf), "Status: %d %s\r\n", SG(sapi_headers).http_response_code, err->str);`
	`len = slprintf(buf, sizeof(buf), "Status: %d\r\n", SG(sapi_headers).http_response_code);`

Removing the CR LFs and explicitly sending them after the header is sent (as per other headers in the code below this) should be sufficient to fix?

Test script:
---------------
<?php
header( 'HTTP/1.1 201 ' . str_repeat( 'A', 1011 ), true );
exit;

Actual result:
--------------
The example above will return the following headers

HTTP/1.1 201 AAA...AAAContent-type: text/html; charset=UTF-8
