This script parses /proc/user_beancounters and tries to output it in a more human-readable format.

1. Held, maxheld, and fail counter are shown for every beancounter.
2. Values that are in pages are converted to bytes
3. Long values are converted to kilo-, mega-, gigabytes etc.
4. For held and maxheld it shows how close the value to the limit, in per cent
5. Can be used both inside CT and on HN

TODO:

• colors
• recognize vSwap
• quieter mode (only show values close to limits and/or with failcnt > 0)
• save failcnt and show the difference from the prev. run
• add interactive mode (top-like) using watch
• add UBC consistency check a la vzcfgvalidate (helpful for CT owner!)
• rewrite in C??
