    - drop the failed byobu-statusd experiment and its byobu-status-print
      helper

    - fix a bug/typo in shutil (should be /proc/uptime)
  * usr/bin/byobu-status-tmux, usr/lib/byobu/.constants,
    usr/share/byobu/profiles/common, usr/share/byobu/profiles/tmux,

    usr/share/byobu/status/Makefile.am, usr/share/byobu/status/status:

  * usr/share/byobu/profiles/common, usr/share/byobu/profiles/tmux:
    - drop backticks and double printing of date/time in tmux
  * usr/bin/byobu-status, usr/bin/byobu-status-tmux => usr/bin/byobu-

    usr/lib/byobu/mem_used, usr/lib/byobu/.shutil,
    usr/share/byobu/status/status, usr/share/man/man1/byobu.1:
    - drop experimental code, no longer necessary
    - test non-zero cache file
    - combine mem_* to memory
    - decrease raid status frequency
    - add trailing space to logo
  * usr/lib/byobu/network:
    - make network calculations drastically cheaper, by using status_freq
      rather than a file stat

    usr/lib/byobu/network, usr/lib/byobu/reboot_required,
    usr/lib/byobu/updates_available:
    - must separate run dirs for tmux/screen run status scripts;

  * usr/lib/byobu/.shutil:
    - fix tmux color rendering
