- Redirect STDERR for the collection part in both tools
- rm_tempdir in sigtrap
- A part of pt-mysql-summary still depended on the system being run,

- get_var sanity
- pt-mysql-summary now follows pt-summary's suit and doesn't take
in files to write to
- pt-summary defers setting the CMD_FOO vars to a function, as
otherwise it would skip our PATH mungling.
