New external dependencies for 2.32: telepathy-logger

[Guillaume Desmottes <gdesmott gnome org>]

Hi,

I'd like to make Empathy depends on the telepathy-logger [1] during the
2.31 cycle.

This module has 2 part:
- A daemon used to logs messages (but will gain support for logging more
events such as calls in the future).
- A library to allow client to easily access logs.

This approach has the following advantages:
- Ensuring that all the conversations are properly logged; even when
using another Telepathy client or if Empathy crashed.
- Allow other applications to retrieve logs; this will be used by
gnome-shell.
- More code shared between Telepathy clients.
- Better Telepathy integration.
- New fancy feature such as displaying the list of contacts to who user
recently talked for example.


Empathy has currently an optional dependency on tp-logger (used by
MeeGo). I plan to remove it to reduce #ifdef in code and be able to
properly implement Approvers [2] in Empathy.
