submodules: Updated dvidclient
BlockwiseFileset: Automatically increase open file limit when the first blockwise fileset is created.
(Now we can actually run the blockwise fileset tests on mac.)
OpCompressedCache: Don't close all cache files every time setupOutputs() is called.
(If the data can't be regenerated, e.g. in a labeling operator, then closing the cache files discards the data.)
OpCompressedCache: Minor refactoring to make it easier for subclasses to use specific member functions.
Also, added a special fast-path to be used by the label array subclass when writing an all-zero block.
OpCompressedUserLabelArray: Refactored as a subclass of OpCompressedCache:
- Now explicitly aware that any data NOT in the cache is automatically zeros.
- Does not create new cache blocks during execute() ONLY during setInSlot().
