Sync goocanvas 1.0 from gnome repo

I am the new maintainer for goocanvas and goocanvas-2.0 in Debian. It should be safe to sync goocanvas from Debian. Goocanvas-2.0 has it's own source package, and the legacy goocanvas (this one) has now been updated from 0.15 in Debian to 1.0 and uses autoreconf to help building on different architectures. All Ubuntu changes at 0.15 have been incorporated in Debian and upstream.

    Source package name: goocanvas
    Source package version number to sync: 1.0.0-1
    Where to sync from: Debian sid main

The previous Ubuntu changelog:
goocanvas (0.15-1.1ubuntu1) trusty; urgency=medium

  * Link libgoocanvas with -lm to fix build failure on ppc64el.
  * Build using dh-autoreconf.
