Rename DEFINE_GLOBALS() to just GLOBALS() (because I could never remember if it was DECLARE_GLOBALS). Convert existing commands to use new infrastructure, and replace optflag constants with FLAG_ macros where appropriate.

760494af5163 mktemp broke kernel build, so new rules: if you don't specify anything, /tmp/tmp.* Specify a file, ./file. Specify -p dir then dir/tmp.*. Specify -p dir and file, dir/file. Also implement -q which lsb wants.
