Subject: alfred: Show error message for invalid batadv interface
The alfred server process always stopped without any informational message
when the provided batman-adv was not "none" and was not accessible. This
made it extremely hard to debug the reason why alfred directly stopped
after launching it.

Subject: alfred: Allow exactly one interface for secondary mode
A primary alfred daemon allows syncing over more than one interface. But
the secondary alfred daemon needs exactly one interface. But the check for
this property was insufficient because it allowed paramters like
"-i wlan0,asd" when wlan0 is valid and asd is not valid.
The better solution is to really use the number of interfaces given to
alfred instead of the number of interfaces evaluated as "valid".

Subject: alfred: Save global mode flags in bitfield
The verbose and ipv4mode entries in the globals structure is only used to
save a boolean information. So just use a bit in a bitfield to store this
information instead of a full int.

Subject: alfred: Allow start of server without valid interface
The alfred server always needs interfaces to operate on. But these
interfaces might not exist at the moment when the daemon process is
started. This caused an error and stopped the process.
But alfred is able to deal with interfaces which disappeared at runtime but
existed at startup. To force a similar behavior for the alfred startup, the
parameter "--force" or "-f" is introduced.
