[PATCH 1/3] network: Initialize variables in networkDnsmasqConfContents()
In networkDnsmasqConfContents() there's a for() loop which
initializes some variables in its initialization block. This
makes both the loop() statement and variable declaration block
look needlessly ugly. Speaking of variable declaration, also move
some variables which are used only within blocks into their
respective blocks.
