This is a simple QR encoder for DRM panic. +//! +//! It is called from a panic handler, so it should't allocate memory and +//! does all the work on the stack or on the provided buffers. For +//! simplification, it only supports low error correction, and applies the +//! first mask (checkerboard). It will draw the smallest QRcode that can +//! contain the string passed as parameter. To get the most compact +//! QR code, the start of the URL is encoded as binary, and the +//! compressed kmsg is encoded as numeric. +//! +//! The binary data must be a valid URL parameter, so the easiest way is +//! to use base64 encoding. But this wastes 25% of data space, so the +//! whole stack trace won't fit in the QR code.

This makes 39bits of compressed data into 12 decimal digits, +//! into 40bits in the QR code, so wasting only 2.5%.
