We have two distinct "library version" numbers: the soname version and the version macros. We need both for different reasons: the version macros enable easy compile-time version detection (and conditional compilation), while the soname version enables runtime version detection (which includes the version checking done by things like the Python bindings). However, currently, these two version numbers are different, which is unnecessary and can lead to confusion (especially in things like Debian, which include the soname version in the package name). This patch makes them the same by bumping the version macros up to agree with the soname version. (We should probably keep the version number in just one place so they can't get out of sync, but that can be done in another patch.)
