Bug Fixes since CGNS 3.3.0 Release

Configuration:
------------------

* Cmake target link libraries need to be set on systems other than just WIN32 and CYGWIN, CGNS-64.
* Support Mac's dylib shared library suffix with CMake, CGNS-61.
* CMake needs to be updated to handle new fortran features, CGNS-10.
* Add missing dependency in cgns_to_plot3d (cmake build), CGNS-16.
* Add missing include path, fix hdf5, PR 18.

Library:
------------
* Hang in parallel read/write, CGNS-105.
* Header files contain functions not existing in code, CGNS-115.
* Fixes for CGNS-83: Large files fail on 64-bit windows.
* Remove incorrect semicolon, PR-13.
* Add missing close paren, PR-15.
* Fix incorrect structured field array access -- cut paste error, PR-17.
* Fix a few missing CGNS_ENUMV uses, PR-20.
* Fix to avoid hang due to collective requirement, PR-21.
* Freeing incorrect pointer, PR-23
* Initialize err, add missing return, PR-25.
* Handle case where wbuf or rbuf is NULL, PR-26.
* Tests can run with ENUM_SCOPING enabled, PR-34.
* Implementation and test for cgp_parent_data_write, PR-36.
* Add cmake support for memory debugging; fix memory debug routines, PR-39.


Fortran:
------------
* Missing C binding for cg_conversion_write_f

Tools:
----------
* cgnsconvert fails to process a file written by the parallel CGNS library, CGNS-77.

Known Problems

• When building with PGI and gcc compilers it might be necassary to set the
  environment variables:
  FLIBS="-Wl,--no-as-needed -ldl"
  LIBS="-Wl,--no-as-needed -ldl"
