[PATCH v2] Rename vcs_to_changelog.py to use hyphens

[Siddhesh Poyarekar]

This was needed earlier because modules had to import the main script,
but that is no longer true.  Rename the script so that it is
consistent with all other scripts in gnulib and uses hyphens.

        * build-aux/vcs_to_changelog.py: Rename to...
        * build-aux/vcs-to-changelog.py: ... this.
        * doc/vcs-to-changelog.texi (VCS To ChangeLog): Update
        reference.
        * modules/vcs-to-changelog: Likewise.
---

Oops, forgot to update documentation, sorry.
