The existing mechanisms for determining what code is running in the kernel do not always correctly report the git hash. The versions reported there do not reflect changes made since `configure` was run (i.e. incremental builds do not update the version) and they are misleading if git tags are not set up properly. This applies to `modinfo zfs`, `dmesg`, and `/sys/module/zfs/version`. There are complicated requirements on how the existing version is generated. Therefore we are leaving that alone, and adding a new mechanism to record and retrieve the git hash: `cat /proc/sys/kernel/spl/gitrev` The gitrev is re-generated at compile time, when running `make` (including for incremental builds). The value is the output of `git describe` (or "unknown" if not in a git repo or there are uncommitted changes). We're also removing /proc/sys/kernel/spl/version, which was never very useful.
