* [file_utils] spin-off syscall-related file operations 1. Eliminate the potential circular dependency between persistent-data/block.h and persistent-data/file_utils.h, if the former one wants to include the latter. 2. Avoid namespace pollution by removing the "using namespace std" declaration in block.tcc. 3. Correct the header hierarchy: base/xml_utils.h now no longer depends on the higher-level persistent-data/file_utils.h * [file_utils] support block files in get_file_length()
