d2316f866c
Primary Fixes: * Add a whole variable optimization -- used in the rare case that nc_get/put_vara covers the whole of a variable and the variable has a single chunk. * Fix chunking error when stride causes whole chunks to be skipped. * Fix some memory leaks * Add test cases * Add one performance test to nczarr_test/. This uses the timer utils from unit_test: timer_utils.[ch]. * Move ncdumpchunks utility from ncdump to nczarr_test Misc. Other Changes: * Make check for aws libraries conditional on --enable-nczarr-s3 * Remove all but one bm tests from nczarr_test until they are working. * Remove another dependency on HDF5 from supposedly non-HDF5 specific code; specifically hdf5_log_hdf5. * Make the BAIL2 macro be hdf5 specific and replace elsewhere with an HDF5 independent equivalent. * Move hdf5cache.c to libsrc4/nc4cache.c because it is used by nczarr. * Modify unit_tests so that some of them are run even if using Windows. * Misc. small bug fixes and refactors and memory leaks. * Rename some conflicting tests for cmake. * Attempted to make nc_perf work with cmake and failed.
