[PATCH v2 2/8] Documentation: use parametrized manpage-base.xsl with manpage-{1.72,normal}.xsl

[Chris Johnsen <chris_johnsen@pobox.com>]

Parametrize the backslash and dot characters that are used to
generate roff control sequences in manpage-base.xsl.

Testing done with asciidoc 8.3.1 and docbook-xsl 1.74.0.

Signed-off-by: Chris Johnsen <chris_johnsen@pobox.com>

Changes since "v1": In manpage-{normal,1.72}.xsl, use
  <xsl:import> to incorporate manpage-base.xsl. Take
  manpage-base.xsl off the xmlto commandline. Thanks, Peff!

  Implementation details in the commit message have been moved to
  the last patch.

---

Still no change in behavior. Just refactoring here.
