expand_number(3)

[John Baldwin]

While working on some bhyve changes I happened to look at the source
to expand_number(3) and noticed what I think are several bugs.  I
wrote some tests to validate that these bugs are present, but in some
cases I'm not sure what the correct / desired behavior is?  I posted
a review with the tests and questions about what some of the behavior
should be with folks who have worked on expand_number(3) previously,
but haven't gotten any feedback.  The URL to the review is below if
other folks would like to offer feedback on some of my open questions
such as should we support negative numbers, hex and octal bases,
trailing garbage, etc.?
