The convert_to_sparse() method checks for the GIT_TEST_SPARSE_INDEX environment variable or the "index.sparse" config setting before converting the index to a sparse one. This is for ease of use since all current consumers are preparing to compress the index before writing it to disk. If these settings are not enabled, then convert_to_sparse() silently returns without doing anything. We will add a consumer in the next change that wants to use the sparse index as an in-memory data structure, regardless of whether the on-disk format should be sparse. To that end, create the SPARSE_INDEX_MEMORY_ONLY flag that will skip these config checks when enabled. All current consumers are modified to pass '0' in the new 'flags' parameter.
