Summary: Update the internal copy of `phpqrcode` from version 1.1.4 (2010100721) to version 1.9.9 (20130526). Single reason is that it adds a lot of documentation which may come handy one day. This more recent code is taken from https://sourceforge.net/p/phpqrcode/code/19/ which equals https://github.com/Darkflib/php-qrcode/blob/master/lib/merged/phpqrcode.php, with our two custom one-line patches still on top. Closes T15878 Test Plan: * Manually diff between old downstream and slightly newer upstream version in a visual diff tool to review the changes. * Go to http://phorge.localhost/settings/panel/multifactor/ and select "Add Auth Factor", select TOTP, click "Continue", still see a QR code properly rendered which works.

__Main class to create QR-code__.
|
|
QR Code symbol is a 2D barcode that can be scanned by handy terminals such as a mobile phone with CCD.
|
|
The capacity of QR Code is up to 7000 digits or 4000 characters, and has high robustness.
|
|
This class supports QR Code model 2, described in JIS (Japanese Industrial Standards) X0510:2004 or ISO/IEC 18004.
|
|
|
|
Currently the following features are not supported: ECI and FNC1 mode, Micro QR Code, QR Code model 1, Structured mode.
