PHP8.1 compatibility

[tsegarra]

I'm trying to install this extension with PHP8.1 on macOS 12.6. All the provided tests fail. It appears the INI variables aren't being read properly, either for testing or for normal use. I get the following warnings:

Warning: [TOMBS] Failed to allocate shared memory for graveyard in Unknown on line 0
Warning: fsockopen(): Unable to connect to 127.0.0.1:8010 (Connection refused)

The tests pass if I hard-code the INI values in the extension code, or if I use PHP7.4.

Is this expected behavior? If so, I can submit a PR updating the README with the supported PHP version range. If not, let me know what other info I can provide.

This appears to have been caused by a change in how ini entries are registered. It was introduced here: php/php-src#8435

A workaround is to use the old function, modifying line 126 of zend_tombs_ini.c as follows:

-    zend_register_ini_entries(ini_entries, -1);
+    zend_register_ini_entries_ex(ini_entries, -1, -1);

After that, all tests pass on PHP8.1. I'm not familiar enough with zend extensions to know whether this is a good practice, but I suspect it isn't. If it is, I can make a proper PR.

Any chance to get this fixed?
