jsoncpp: Build the library within CMake

Update json/json.h to account for our lack of autolink.h.  Update
json/config.h to include KWSys Large File Support configuration so that
consistent stream libraries are used (on AIX with XL).

Add a cm_jsoncpp_reader.h header to include the CMake-provided copy of
the json/reader.h header from CMake sources.
