Upgrader - undefined function "allowedTo()" errors

[sbulen]

Description

You will likely only see this on large DB upgrades. One cause of this is that, although the upgrader tries to chunk up its work into smaller pieces, sometimes the pieces are still too big. Reducing the size of the $limit used for that step fixes the issue.

When the upgrader reports an undefined function allowedTo(), that means the true error is obfuscated. This error gets reported during the error reporting process for the previous error... 🙄

Flagging for 2.1.5 as this is an easy fix. Should likely change all of the
$limit = 100000;
to:
$limit = 10000;

100K inserts/updates is a pretty big bite. Small forums, no problem, you likely don't run into the limits. But you sure might for bigger forums on smaller servers...

Steps to reproduce

1. Upgrade a forum on a shared server (lower memory settings) with hundreds of thousands of board or topic watches to migrate...

Environment (complete as necessary)

• Version/Git revision: current
• Database Type: mysql
• Database Version: 5.7
• PHP Version: 8.2
