  -----------
  Stricter validation of article numbers

This brings the implementation largely in line with RFC3977, and fixes
anomalous behavior when very large article numbers are passed in NNTP
commands, e.g. OVER reduces the article number mod 2^32 and then
returns an unexpected range of articles.

Adds tests for IsValidArticleNumber and IsValidRange.

  Log Message:

  Rename lib/numbers.c to lib/artnumber.c

It is a better name for this file, now we also have a test suite for
article numbers.
Also, add credits to Richard Kettlewell for his improvement in article
validation.
