Restore scripts/make_gitrev.sh Commit 109d2c931020 ("Move zfs_gitrev.h to build directory") removed scripts/make_gitrev.sh, putting the logic into the Makefile itself. However, at least the Arch Linux packager wants the script so that the file can be generated without having to run configure first, for DKMS packaging purposes. So move the make recipe back into the script.

# Generate zfs_gitrev.h. Note that we need to do this for every

Add zfs_gitrev.h to the distributed sources Commit 109d2c931020 ("Move zfs_gitrev.h to build directory") stopped distributing zfs_gitrev.h, as it is a generated file. Add it back, with some changes in behavior. Change the logic for gitrev as follows - if the source tree is a git repository, the behavior for build is unchanged. For make dist, append -dist to the git tag in the distributed version of zfs_gitrev.h. - otherwise, check if the source tree contains zfs_gitrev.h, and use it if so, falling back to "unknown" if it doesn't exist. - clean it only in make maintainer-clean, so we don't remove it from the source tree on make clean or make distclean. This allows disted sources to track what git tag they originally came from, with the -dist suffix indicating that the code wasn't built directly from git and so might contain additional changes beyond the git tag.
