 *
 * This set of API calls returns two different version numbers related
 * to libsigrokdecode. The "package version" is the release version number
 * of the libsigrokdecode tarball in the usual "major.minor.micro" format,
 * e.g. "0.1.0".
 *
 * The "library version" is independent of that; it is the libtool version
 * number in the "current:revision:age" format, e.g. "2:0:0".
 * See http://www.gnu.org/software/libtool/manual/libtool.html#Libtool-versioning for details.
 *
 * Both version numbers (and/or individual components of them) can be
 * retrieved via the API calls at runtime, and/or they can be checked at
 * compile/preprocessor time using the respective macros.
