* Update to version 5.1.0: See https://blog.kitware.com/itk-5-1-0-available-for-download/.
* Drop dcmtk-cmake.patch: no longer needed when using system dcmtk.
* Update itklbfgs-linking.patch and nrrdio-linking.patch to upstream-blessed versions (minor changes only) [gh#InsightSoftwareConsortium/ITK#1867, gh#InsightSoftwareConsortium/ITK#1878].
* New BuildRequires: pkgconfig(libpcrecpp) and bison.
* Drop BuildRequires: tcpd-devel, no longer needed.
* Add necessary Requires: python3-numpy to python3-%{name} package.
* Update Requires for devel package and convert existing Requires to pkgconfig equivalents where possible.
* Pass -DITK_USE_SYSTEM_SWIG:BOOL=ON to cmake, otherwise it defaults to OFF and tries to download swig.
* Drop -DITK_USE_STRICT_CONCEPT_CHECKING:BOOL=ON option passed to cmake: no longer used.
* Drop -DITK_WRAPPING option passed to cmake: obsoleted by -DITK_WRAP_PYTHON.
* No longer need to `export CXXFLAGS+=" -I%{_includedir}/gdcm/"` [gh#InsightSoftwareConsortium/ITK#1768].

* Update to version 5.0.1
* Drop add_gcc9_support.patch: no longer required with upstream support for up to GCC 10 baked in.
* Pass options to %cmake to set proper install paths when installing; prevents the need to manually move installed libs around. Drop sed BuildRequires that is no longer required as a consequence.
* Enable python3 wrapping (needed for tomviz, for instance); split out separate python3-itk package. Introduces BuildRequires: python3-devel.
* Add BuildRequires: memory-constraints and use %limit_build to require at least 2 GiB memory per thread; OOM failures otherwise.
* Update _constraints file: at least 24 GB (!!!) disk space and 2 GB memory now required.
* Use ninja for build (BuildRequires: ninja); compile using %cmake_build instead of make directly.
* Additional system library dependencies: CastXML-devel, gtest, double-conversion, and gdcm-devel.
* Convert BuildRequires to pkgconfig() or cmake() based ones wherever possible.
* Update URL and Source URL in keeping with upstream's move to github.
* Drop conditionals for old openSUSE versions.
