Export snr_to_signal to other source files. This will be necessary to
determine reported signal strengths from beacon-report throughout the
code base.

When kicking clients due to high channel load, explicitly only select
new candidates in case their channel load is an improvement over the
current node.

It is not necessary to check if the candidate is not considered
reverse-better, as this is already done inside is_better_candidate for
all relevant criteria.

A unset bitmask leads to the candidate selection always return no
candidate, even if there is one.
To select a better candidate regardless of it's classification, provide
a bitmask containing all selection criteria.

When determining a new node within the roam state machine, require the
destination node to have a better reported signal from the client.
Otherwise, the roam state machine might trigger a roam action for a
unsuitable destination node.

When checking whether a client is allowed to associate to a node, the
lower ceiling for kicking clients was not taken into account when
assoc-steering is disabled.
The problem behind this is, that a configured lower barrier for
disassociating clients (kicking) would kick the client immediatly after
association. In the worst scenario the client immediatly associates
again to the station and ends up in a kick loop.
Don't allow associating when a min_snr is configured and the client
signal is below this value.

Make the connection state of a sta-info more readable by introducing an
enum for the STA connection state.
Also switch come comparison cases to use the explicit enum values to
make the code more readable.
