More symbol work.

I've defined a few macros to help with module/request init/startup function definitions.
Basically:

PHP_MINIT_FUNCTION(module)
PHP_MSHUTDOWN_FUNCTION(module)
PHP_RINIT_FUNCTION(module)
PHP_RSHUTDOWN_FUNCTION(module)
PHP_MINFO_FUNCTION(module)

These will expand to proper function prototypes.

Now to specify these in the module entry, use:

PHP_MINIT(module)
PHP_MSHUTDOWN(module)
PHP_RINIT(module)
PHP_RSHUTDOWN(module)
PHP_MINFO(module)

I've updated all modules in ext/standard and everything from ext/apache to ext/db.
If you can, please update your module to use these macros.
