git-extract-tag: remove dead code
goto-vim: trim trailing newlines
git-mkobject: nuke (useless wrapper around `git hash-object`)
git-verify-commit: nuke (Git 2.1 has the real thing)

Besides, this one was incomplete anyway.
remove unused files
install-rbenv: nuke (rbenv shims are slow)
iconv-bruteforce: nuke
imapmail aka mail aka m: nuke
recordmail{,-dup}: nuke
offlineimap-mutt-cache: nuke
freenet-monitor.py: rename to `freenet-dl`
http-get: fail if libraries cannot be loaded
move lib*.bash to lib/bash/
libnetctl.bash: nuke

My 'netctl' stopped existing long ago. The only useful remaining thing
in libnetctl is the `/usr/lib/virtualbox/VBoxNetAdpCtl` command, which I
note here for future reference.
remote.mpc: nuke
rwhod.sh: add a warning message for cronmail

I'm really curious if I have any remaining cronjobs where this is used.
update-etchosts.py: nuke

Originally I had added this to guard against certain domain names
going down sometimes and breaking my stuff. I doubt I'll ever need this.
(Although it *would* work on Linux I think...)
ttysize: nuke (same as `stty size`)
upowermon.pl: rename to `upower-monitor`
xnamei: nuke (unused)
