Description:
------------
Executing "php-fpm -i" crashes. This is due to the commit abb616ae which is a merge of the cgi commit 6bc16cce to fpm.

The crash happens, because in sapi/fpm/fpm/fpm_main.c in function sapi_cgi_register_variables() the variable request is NULL in line

char *path_info = FCGI_GETENV(request, "PATH_INFO");

Before the merge the line was

char *path_info = sapi_cgibin_getenv("PATH_INFO", sizeof("PATH_INFO") - 1);

and sapi_cgibin_getenv() falls back to simple getenv() if request is NULL (and also if fpm_is_running is not set. The original change in cgi should not have this problem, only the port to fpm can execute "phpinfo" without actually running a real request.

I'll try if it is enough to simply change the one line back for a fix, or if the crash then moves to a later place in code and more work needs to be done.

Test script:
---------------
Run php-fpm -i
