* This introduces an internal API query function named zaxisInqNamePtr.

merged trunk into cdi_conversion_c++ and changed type of len in function serializeStrTabGetSize() to int, removed anonymous function in serializeStrTabGetSize() and replaced it with &len

replaced designated initializer with manual initialization for struct varDefZAxisSearchState since c++ does not support this feature, added explicit casts in various files

* r3363: merged changes from branches/cdi_fileDrivenInput

* Also rename some functions to include cdi prefix.

* Because it holds the namespace the unpacked resource comes from.

* And make use of this capability in Z-axis.
