[PATCH 2/3] Added more version defines to tools/version.h.in.

[Thomas Woerner <twoerner@redhat.com>]

Modified tools/version.h.in and configure.in:
New defines LVM_MAJOR, LVM_MINOR, LVM_PATCHLEVEL and LVM_RELEASE generated in
configure. Maybe a rename of version.h.in to lvm_version.h.in would be good to
prevent name conflicts with other projects. Added GPL header to version.h.in.

TODO: recreate configure
