PHP LiteSpeed SAPI patch

Hi, Attached is the code for PHP LiteSpeed SAPI. To apply the patch, just expand it under php/sapi/ directory, run buildconf, then configure PHP with option "--with-litespeed". The patch can be applied to both PHP 4 & 5. LiteSpeed SAPI is similar to CGI/FastCGI sapi, two major enhancements over FastCGI sapi, one is support of changing PHP configuration via web server configuration and .htacess file; another one is improved performance over FastCGI PHP and Apache mod_php, our simple "hello, world" performance test shows that LiteSpeed SAPI has up to 30% performance advantage over FastCGI PHP, and doubles the performance that Apache mod_php can provide. PHP with LiteSpeed SAPI works together with litespeed web server 2.1RC1 release. For more information about this SAPI module, please visit http://www.litespeedtech.com/lsapi/ and http://www.litespeedtech.com/docs/HowTo_QA.html#qa_php We are new to PHP SAPI programming and we use cgi/cli/apache/thttpd SAPI code as references, please help reviewing our code. Any comment or suggestion is highly welcome. :-) Thanks, George Wang
