Fixed warnings and notices issued by PHP 8.1.4

[BertHooyman]

several api functions (decodeTriple and decode) returned either an object or an int 0. This leads to warnings in the calling code under PHP 8.1. As a fix, these functions now return null rather than 0.

In various places, associative arrays were accessed using non-existing keys. E.g. $GLOBALS['redivar'], $_REQUEST['s'], $_GET['edge'] and $_GET['start']. Code has been extended to avoid such access.

In the function territory_code_tests() in unittest.php, there was a $testdata array entry for 'US-CA OTHER TEXT' having a context of '-1 -1'. This is evaluated as -2 and that leads to a warning in PHP 8.1. The context has been fixed to '-1'

Indexing into an uninitialized array leads to warning in PHP 8.1. This has been fixed for accessing $result[$p] in to_ascii()
