mingw64-zlib-1.2.13-bp160.1.16

- Use absolute path to change into minizp source dir to be independent
  from the current path used by mingw64-cross-cmake provided
  macros
- Drop obsolete build dependencies (boo#1201119)

- Fix not finding zconf.h and libz.dll.a with autotools submodule build
- Fix warning that package obsoletes itself

- update to 1.2.13:
  * Fix configure issue that discarded provided CC definition
  * Correct incorrect inputs provided to the CRC functions
  * Repair prototypes and exporting of new CRC functions
  * Fix inflateBack to detect invalid input with distances too far
  * Have infback() deliver all of the available output up to any error
  * Fix a bug when getting a gzip header extra field with inflate()
  * Fix bug in block type selection when Z_FIXED used
  * Tighten deflateBound bounds
  * Remove deleted assembler code references
  * Various portability and appearance improvements

- Fix cmake macro usage (boo#1205135)

- Update to 1.2.12
  * Fix a deflate bug when using the Z_FIXED strategy that can
    result in out-of-bound accesses. (bsc#1197459)
  * Fix a deflate bug when the window is full in deflate_stored().
  * Speed up CRC-32 computations by a factor of 1.5 to 3.
  * Use the hardware CRC-32 instruction on ARMv8 processors.
  * Speed up crc32_combine() with powers of x tables.
  * Add crc32_combine_gen() and crc32_combine_op() for fast combines.

- Remove brackets from build macro calls to use common style

- Add runtime package as dependency to development package to fix
  running cross compiled application (boo#1194430)

- Modernize specfile for Factory resubmission:
  * trim rpmlintrc/post-build-checks ignores to minimum
  * apply descriptions from main zlib.spec
  * replace old specfile constructs like %defattr

- Add rpmlintrc file to silence some rpmlint errors that make
  the build fail.

- migrate to cmake to support static library
  (Adapting the custom configure script required too much effort)
- use mingw filename pattern for shared library (libz.dll) to
  prevent conflicts with preinstalled z libraries on native Windows
- let zlib1.dll still be existant for compatibility
