gnu: Fix ambiguity between openssl package and license in tls module.

* gnu/packages/tls.scm: Prefix imported licenses.

gnu: icecat: Add support for WebGL, CUPS, Hunspell, startup-notification, etc.

Also remove most bundled libraries from the source, add comments about
libraries yet to be unbundled, explicitly link libxul.so with libraries that
might try (and fail) to dlopen, and remove the h264parse gstreamer module from
the blacklist.

* gnu/packages/gnuzilla.scm (icecat)[source]: Add snippet.
  [inputs]: Add cups, gdk-pixbuf, glib, hunspell, libcanberra, libgnome,
  libxinerama, libxscrnsaver, mit-krb5, and startup-notification.
  [arguments]<#:configure-flags>: add "--enable-default-toolkit=cairo-gtk2",
  "--enable-pango", "--enable-gio", "--enable-svg", "--enable-canvas",
  "--enable-mathml", "--enable-startup-notification", "--disable-gnomevfs",
  "--disable-gconf", "--disable-gnomeui", and "--enable-system-hunspell".
  Remove outdated comment about "--with-system-bz2" not being used.
  <#:phases>: Use 'modify-phases'.  Add 'remove-h264parse-from-blacklist'
  and 'arrange-to-link-libxul-with-libraries-it-might-dlopen' phases.
