[svn-r29182] Re-commit of HDFFV-8740 fix, which adds the ability to configure
external dataset storage path behavior. This check-in fixes a bug in the original check-in where the external path stored in the file struct was not copied on reopen causing subsequent dataset operations to fail. Tested on: 64-bit Ubuntu 15.10 (Linux 4.2.0 x86_64) gcc 5.2.1 autotools serial w/ fortran and C++ autotools parallel (MPICH 3.1.4) w/ fortran
