Reduce coupling with bundled Zopfli library

Add ZLIB_LIBS and ZLIB_CFLAGS variables to the Makefile to make it easy to

2020-10-20T22:15:37+00:00

control linking against zlib, just as we added ZOPFLI_LIBS and ZOPFLI_CFLAGS
for the Zopfli library.

Add ZOPFLI_LIBS and ZOPFLI_CFLAGS variables to the Makefile to make it easy to

2020-10-20T22:13:00+00:00

build with an external Zopfli library. Set their default values such that the
bundled Zopfli library is still used by default. Re-order the linker flags so
that both cases work as expected.

Fix linker flag order

Use only Zopfli public API functions from zopfli.h.

The Zopfli library is normally installed only with zopfli.h (and
zopflipng_lib.h). Using only APIs in this header makes it easier to use an
external Zopfli library. This means including zopfli.h instead of
zlib_container.h, and calling ZopfliCompress with ZOPFLI_FORMAT_ZLIB instead of
calling ZopfliZlibCompress directly.

Add support for external CPPFLAGS/CFLAGS to the Makefile

Add full text of the three WOFF licenses:

2020-10-20T18:32:20+00:00

  - LICENSE-WOFF-MPL, from
    https://www.mozilla.org/media/MPL/1.1/index.0c5913925d40.txt
  - LICENSE-WOFF-GPL, from
    https://www.gnu.org/licenses/old-licenses/gpl-2.0.txt
  - LICENSE-WOFF-LGPL, from
    https://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt

Update the WOFF license file with the full text from upstream, matching the

2020-10-20T18:28:13+00:00

license comment blocks in the source files, from
https://raw.githubusercontent.com/samboy/WOFF/2017-06-11/LICENSE.

Update the Zopfli license file (LICENSE-ZOPFLI) to contain the complete Apache

2020-10-20T18:23:14+00:00

2.0 license text from
https://raw.githubusercontent.com/google/zopfli/zopfli-1.0.3/COPYING rather
than a brief summary.

Split license terms for extended/modified WOFF sources and bundled Zopfli

2020-10-20T18:19:51+00:00

sources into separate files. Add a COPYING file to summarize which terms apply
to which sources.

Move bundled zopfli sources into a new zopfli/ subdirectory.

2020-10-20T17:45:03+00:00

Separating source files by origin (and license) makes it easy for users who
want to build with an external zopfli library to remove the bundled sources,
ensuring they are not used. Unbundling libraries is mandatory for packaging in
many popular Linux distributions, and can be useful for other applications as
well. Additional changes will be needed to make it easy to select an external
zopfli library.
