Corrected "BAIL" macros to avoid infinite loop when logging is disabled and an error occurs after an "exit:" label. Corrected a dozen Coverity errors (mainly allocation issues, along with a few other things): 711711, 711802, 711803, 711905, 970825, 996123, 996124, 1025787, 1047274, 1130013, 1130014, 1139538 Refactored internal fill-value code to correctly handle string types, and especially to allow NULL pointers and null strings (ie. "") to be distinguished. The code now avoids partially aliasing the two together (which only happened on the 'write' side of things and wasn't reflected on the 'read' side, adding to the previous confusion). Probably still weak on handling fill-values of variable-length and compound datatypes. Refactored the recursive metadata reads a bit more, to process HDF5 named datatypes and datasets immediately, avoiding chewing up memory for those types of objects, etc. Finished uncommenting and updating the nc_test4/tst_fills2.c code (as I'm proceeding alphabetically through the nc_test4 code files).
