Upstream provides distfile via githubs release infrastructure.

- Move from GH_* to MASTER_SITES and DISTNAME
  * Set EPOCH as version numbering has changed
  * Set HOMEPAGE
- No need to pull in automake and libtool
  * Drop BDEPs
  * Change CONFIGURE_STYLE
- Follow Makefile.template
- Change email address MAINTAINER

OK jca@, sthen@
