The project previously used the `time` crate for getting the current
time in the local timezone. It was discovered that the time crate would
fail to return the local time when the program used multiple threads,
because of concerns that the other threads could modify timezone-related
environment variables while the timezone was being read from the system
and create a soundness issue. A second program thread was introduced
recently by commit 1a830a3 to provide non-blocking reads of standard
input for the local stream device, and so the time returned by the
clock device was falling back to UTC.
To fix this, the `time` crate has been replaced by the `chrono` crate
which does not suffer from this restriction, and in any case seems to
be the more popular of the two anyway.

This is a complete rewrite and restructure of the entire emulator
project, as part of the effort in locking down the Bedrock specification
and in creating much better tooling for creating and using Bedrock
programs.
This commit adds a command-line argument scheme, an embedded assembler,
a headless emulator for use in non-graphical environments, deferred
window creation for programs that do not access the screen device,
and new versions of phosphor and bedrock-core. The new version of
phosphor supports multi-window programs, which will make it possible to
implement program forking in the system device later on, and the new
version of bedrock-core implements the final core specification.
