Arnaud Ferraris d9256251fd src: implement config file lookup and initial parsing
This commit prepares the use of device-specific configuration files. 
These files should be named after the device-tree `compatible` string 
with the `toml` extension.

`eg25-manager` will search for config files in 
`<prefix>/etc/eg25-manager` first (or `/etc/eg25-manager` if prefix is 
`/usr`), then in `<prefix>/share/eg25-manager`.
