* Global

- Use string for network exchanges?
- Mark arguments as const in function headers if needed
   That is done in the owlps-positioning C++ code, but not constantly
   in C modules.
- Allow to use hostnames instead of IP addresses.


* libowlps

- Prefix types with "owl_". Rename some of them (lowercase, at least).
- Remove timestamp_to_ms()
   This function is used only by the aggregator to test if a TIMESTAMP
   is null. We should create a function to test that, instead of
   converting to ms every time.
- mac_bytes_to_string(): do not malloc anymore.


* Aggregator

- Use inet_ntoa() instead of ip_bytes_to_string().
- monitor_couples(): rename 'demande' variable.
- Use locks to read/write the AP list
   Currently, several threads can access the list simultaneously, and
   that's not cool!
- Allow blank parameters for output options.
- Fix segfault on SIGINT.


* Listener

- read_packet(): use ieee80211_header_size for all implicit packets
   Currently the size is corrected only for data packets.
- Fix SIGTERM handling
   Sometimes owlps-listener refuses to quit on SIGTERM.
- Fix segfault when rtap_iface is not in monitor mode (?) on Foneras.
- Merge Makefile and Makefile_atheros?
   Use autohell?
- Use positive (USE_CONFUSE) and negative (NO_USE_PTHREAD) options?
   The default options could be modified, but that's not so important,
   is it?


* Client

- Check the direction
   The direction provided by the user should be one of the four
   possible values.
- Allow to use a string for the direction
   Could be nice, but probably useless.


* Positioning

- Has its own fat TODO file, which I should translate.


* writeInDb

- Do something about that
   ° Merge in owlps-positioning?
   ° Delete?


* mobile-centred

- Has its own TODO file.
- Maybe we should delete that.
