Many patches. I hope I remember them all:

- Make sapi_module available to external modules (PHPAPI)
- Make the php.ini path reported in phpinfo() always point to
  real full path of the php.ini file
- Optimized the ISAPI module not to read unnecessary server
  variables and read necessary variables at most once.
