Bug description:  Extensions from php.ini get loaded several times per process 

PHP4 under Apache tries to load extensions from php.ini
several times per process causing 'duplicate name' warnings
Also on the second (and next) loading extension name passed
to phpdl() in damaged form.

Investigation showed that problem is in the main/php_ini.c:
1. php_load_function_extension_cb() allocates extension name using estrdup but global 
llist with extensions declared as persistent. It keeps references to deallocated 
extensions' names causing damaged names passed to phpdl(). 
2. php_startup_loaded_extensions() doesn't free llist after
loading extensions, so next call to php_init_config() (per-process) will double this 

Solution is to deallocate llist after loading extensions in 
php_startup_loaded_extensions. Then (1) wouldn't be a problem at all.

Proposed fix:

--- main/php_ini.c.orig Tue Mar  6 13:38:55 2001
+++ main/php_ini.c      Thu Mar 15 13:12:04 2001
