For basic uspot setups, this commit implements a 'generate' verb to
uspot /usr/bin/captive that takes a config uspot section name, and
parses the following extra options to generate the relevant spotfilter
config:
option generate_spotfilter (bool) # if unset/false, generate is a NOP
option interface 'name' # config/network interface name to redirect to
option client_autoremove (bool) # if set/true, sets client_autoremove
list wl_hosts '*.example.com' # optional list of whitelist hostnames
list wl_addrs '1.2.3.4' # optional list of whitelist IPs
"captive generate" is called in spotfilter.init to optionally (depending
on 'generate_spotfilter') create the required spotfilter-XXX.json before
starting spotfilter.

The current uspot config uses a single named section to assign ifnames
to uspot interfaces like so:
config devices 'devices'
option wlanc0 'hotspot1'
option wlanc1 'hotspot1'
Where 'wlanc0' and 'wlanc1' are physical ifnames.
Code in common.uc also hardcodes a check to match ifnames with 'wlanc*'.
This comit gets rid of the "config device" sections and accepts in the
"config uspot" sections e.g.:
option ifname 'wlanc0'
or
list ifname 'wlanc0'
list ifname 'wlanc1'
The listed devices are then associated with the current uspot config
exactly as they were with the previous configuration system.
The hardcoded check in common.uc is also removed, allowing arbitrary
ifnames to be used.
Malformed sections are ignored with a warning. Subsequent duplicate
entries for a given ifname are be ignored with a warning.
