Fix `reason` list for monitor

Fix markdown formatting for the list of reasons that can be produced
when a process exits.

Add README.md

Add a README that clarifies that this is a fork of hardwood. This still
retains the link to the original source, since folks might want that,
especially if hardwood is ever updated.

Add LICENSE.txt

This is to add the license under a specific file so it can be more
easily discovered by tooling. The license text is taken from the source
header of hardwood-impl.scm.

Update for Chicken 5

Update hardwood for Chicken 5 support.

  * Add a .egg file to build for Chicken 5.

  * Replace data-structures with queues. Looking at whether it's
    feasible to replace the queues with mailboxes to reduce the amount
    of work spent on them, at the cost of putting the primordial thread
    off limits for a process. For now, though, tests pass, so it's
    a start.

  * Replace uuid with ksuid. There is little reason for this other than
    that I know the ksuid egg and prefer it.
