Merge branch 'master' into meta

* master: (27 commits)
  t/test.sh: 'ls' on NetBSD sets -A by default as root; work around it.
  README: add a list of binary packages
  README: rework the title hierarchy
  Clarify the message when the BUP_DIR doesn't exist.
  Refactor: unify ls/ftp-ls code
  ftp/ls: Adjust documentation
  ls: include hidden files when explicitly requested
  ftp: implement ls -s (show hashes)
  ftp/ls: columnate output attached to a tty, else don't
  ftp: don't output trailing line for 'ls'
  ftp: output a newline on EOF when on a tty
  config: more config stuff to config/ subdir, call it from Makefile.
  cmd/{split,save}: support any compression level using the new -# feature.
  options.py: add support for '-#' style compression options.
  Add documentation for compression levels
  Add test case for compression level
  Add compression level options to bup save and bup split
  Make zlib compression level a parameter for Client
  Make zlib compression level a parameter of git.PackWriter
  Use is_superuser() rather than checking euid directly
