    [skip ci] Several UPGRADING fixes

    Use JSON_PRETTY_PRINT, the constant exposed to PHP code, instead of the internal
    C macro PHP_JSON_PRETTY_PRINT in the json_encode() performance note.

    Qualify url_percent_encode() as Uri\WhatWg\url_percent_encode() to match its
    declared namespace. Uri\url_percent_encode() does not exist.
