This extends the release script to check the supplied version
argument against the one found in the toplevel CMakeLists.txt.
This also extends the script to create a VERSION file with the
Ceres version, Ceres ABI version, and commit corresponding to the
tarball.
For example, the VERSION file might like this:
version 1.3.0
abi_version 1.3.0
commit c161a9d0b8
