[svn-r15015] Description:
Detect chunks that are >4GB before dataset gets created and return error to application. Tweak lots of internal variables that hold the chunk size/dimensions to use an 'uint32_t', instead of a 'size_t', so that the integer size is constant. Correct a number of our tests which were creating datasets with chunks that were >4GB and add some specific tests for >4GB chunk size detection. Minor whitespace & other code cleanups. Tested on: Mac OS X/32 10.5.2 (amazon) Forthcoming testing on other platforms...
