Changes:
- Fix: XML output had extra commas, broken since previous version
- Fix: unintended shared pointer modification in mosecs() sometimes resulted
in wrong month name to be shown for the current month
- Fix: possible buffer overflow in /proc/net/dev parsing, requires corrupted
content in /proc/net/dev or use of address sanitizer
- Use ANSI escape codes in -l and -tr modes for cursor location manipulation
instead of printing backspaces, hide cursor while output is active
- Improve database import robustness
- Improve support for Asian UTF-8 date strings
- Replace hand written Makefiles with Autotools
- Add --alwaysadd parameter to daemon for allowing automatic addition of
interfaces even if the database directory was populated during startup
