/*
 * Check the version number API calls and macros.

 * The string representations of the package/lib version must neither be
 * NULL nor empty, and the length shall be within an expected range.
 *
 * The lower limit assumes:
 * - A version text consists of three parts (major, minor, micro),
 *   like "0.1.0".
 * - Three numbers with at least one digit, and their separators,
 *   result in a minimum length of 5.
 *
 * The upper limit assumes:
 * - The major, minor, and micro parts won't contain more than two
 *   digits each (this is an arbitrary choice). The three numbers
 *   are separated by a period character.
 * - An optional "-git-<hash>" suffix might follow. While git(1)
 *   defaults to 7 hex digits for abbreviated hashes, projects of
 *   larger scale might recommend to use more digits to avoid
 *   potential ambiguity (e.g. Linux recommends core.abbrev=12).
 *   Again, this is an arbitrary choice.
 * - An optional "-dirty" suffix might follow.
