/*----------------------------------------------------------------------------
** quic.c
** This file was created initially by performing a gcc -E on the spice
** quic code. Utility functions were then added. It is then passed through
** emscripten to create an initial quic.js, which is also then mangled a bit
** (see quic.shell), to create a quic.js we can use with our Javascript client.
** FIXME: Take this out back and kill it.
