libgpiod-1.3-bp151.1.4

- Add conflicts with libgpiod1 to help upgrade

- devel package now requires libgpiod and libgpiodcxx

- Move libgpiodcxx to its own package

- Update to 1.3:
  * New features:
  - the gpio-tools now have automatically generated (using help2man) man pages
    that are bundled with the release tarball
  - support a singular 'default_val' argument in Line.request() in python
    bindings
  - the test executable can now be installed to the bindir along with the
    gpio-tools and the testing framework will look for the binaries in standard
    locations if it's not run from the top source directory
  - gpiomon now supports line buffered output
  * Improvements:
  - tweaks to the C API documentation
  - treewide unification of the naming of local variables
  - extended helptest in gpioset (explanation of the way the character device
    works aimed at reducing user confusion when a GPIO line reverts to its
    default value after gpioset exits)
  - the source directories have been rearranged and the src/ directory was
    dropped, lib/ and tools/ now live in the top source directory
  - minor coding style fixes in python bindings, ctxless functions and tools
  - automatically generated documentation is now removed by 'make clean'
  - all Makefiles now use top_builddir instead of relative paths
  - code shrink in configure.ac
  - add a brief section about API documentation to README
  * Bug fixes:
  - fix a segfault causing bug in C++ bindings
  - make bitset_cmp::operator() const as this is required by C++17
  - ignore 'remove' events from udev in the testing framework
  - don't segfault on num_lines = 0 in ctxless functions

- Update to 1.2:
  * New features:
  - new contextless event monitor that should replace the previous event loop
    which caused problems on hardware that doesn't allow to watch both rising
    and falling edge events
  - port gpiomon to the new event monitor
  - deprecate event loop routines
  * Improvements:
  - many minor improvements and tweaks in the python module
  - new test cases for python bindings
  - add much more detailed documentation for python bindings
  - coding style improvements in gpio-tools
  - remove unicode characters from build scripts
  - improve the help text messages in gpio-tools
  - make gpiod_chip_open() and its variants verify that we're really trying to
    open a character device associated with a GPIO chip
  * Bug fixes:
  - fix memory leaks in python bindings
  - fix a memory corruption bug in python bindings
  - fix the default_vals argument in line request implementation in python
    bindings
  - fix a compilation warning in python bindings
  - fix gpiod_Chip_find_lines() for nonexistent lines (python bindings)
  - add a missing include in C++ bindings examples
  - correctly display the version string in gpio-tools

- Add python binding

- Update to 1.1.1:
  * Bug fixes:
  - fix memory leaks in python bindings
  - fix a memory corruption bug in python bindings
  - fix the default_vals argument in line request implementation in python
    bindings
  - fix a compilation warning in python bindings

- Update RPM groups. Reorder sentences to put the library first,
  and the old sysfs interface last.

- Add C++ bindings

- Initial package version 1.1
