Bug#771750: [lintian] rename dep5-copyright tags to copyright-1.0

Package: lintian
Version: 2.5.30+deb8u3
Severity: wishlist

Lintian currently refers to "dep5" copyright issues and tags, but
the "DEP-5" references have been deprecated in favor of "copyright 1.0":

   https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/

so these tags could be renamed as "copyright 1.0" (or "1.x"), which I
think would make them more clear.

Having a look at checks/source-copyright.[desc|pm] this involves the
following tags which could be renamed::

   no-dep5-copyright
   syntax-error-in-dep5-copyright
   obsolete-field-in-dep5-copyright
   comma-separated-files-in-dep5-copyright
   empty-short-license-in-dep5-copyright
   invalid-short-name-in-dep5-copyright
   space-in-std-shortname-in-dep5-copyright
   bad-exception-format-in-dep5-copyright
   missing-license-paragraph-in-dep5-copyright
   missing-license-text-in-dep5-copyright
   unused-license-paragraph-in-dep5-copyright
   unknown-paragraph-in-dep5-copyright
   field-name-typo-in-dep5-copyright
   ambiguous-paragraph-in-dep5-copyright
   invalid-escape-sequence-in-dep5-copyright
   wildcard-matches-nothing-in-dep5-copyright
   unused-file-paragraph-in-dep5-copyright
