The exception handler parameter has to be of type `Throwable`, but we
are remaining compatible with PHP 5.6, which didn't have `Throwable`,
so let's fix this by moving the type to the phpDoc block.
Fixes: https://github.com/e107inc/e107/issues/5072
* `strftime()` has been replaced with a polyfill based on `DateTime`.
* Explicit type casts/assertions added where required by PHP 8.1
* `filter_var(…, FILTER_SANITIZE_STRING)` replaced with `strip_tags()`
or HTML entity encoding of quotation marks, depending on a guess of
what the intended "sanitization" was
* `http_build_query()` usage type mismatches fixed
* Removed usages of the `FILE_TEXT` constant
* To avoid breaking PHP 5.6 compatibility (function return types),
`e_session_db` no longer implements `SessionHandlerInterface`.
Instead, the alternative non-OOP invocation of
`session_set_save_handler()` is used instead to apply the session
handler.
* The shim for `strptime()` still calls the native function if available
but now suppresses the deprecation warning.
* `e_db_pdo` explicitly asks for `PDO::ATTR_STRINGIFY_FETCHES` to
maintain consistent behavior with past versions of PHP.
* `e_db_mysql` explicitly sets `mysqli_report(MYSQLI_REPORT_OFF)` to
maintain consistent behavior with past versions of PHP.
* Removed pointless random number generator seed from `banner` plugin
* Workaround for `COUNT(*)` SQL query in
`validatorClass::dbValidateArray()` without a proper API for avoiding
SQL injection
Instead of every independently operating client code figuring out its
own autoload policies, the e107 class file e107_class.php now takes care
of autoloading.
Any client that uses the e107 class will automatically benefit from
autoloading for e107.
This cuts down on potential code duplication, and e107::getSingleton()
is no longer tied to trying to figure out the class path.
This commit REMOVES support for the unused constant flag
E107_DISABLE_AUTOLOAD introduced in
bdef2707b4cafe34e5485d8733138a0e87f43a39 and the unused autoload code
introduced in f4cee9289087c0119bc6797f7dfb7792a62b0be3.
