When attempting to use any of the functions in network.sh while netifd is
not started yet, the ubus interface dump query will fail with "Not found",
yielding an empty response.
Subsequently, jsonfilter is invoked with an empty string instead of a valid
JSON document, causing it to emit a second "unexpected end of data" error.
This caused the dnsmasq init script to log the following errors during
early boot on some systems:
procd: /etc/rc.d/S19dnsmasq: Command failed: Not found.
procd: /etc/rc.d/S19dnsmasq: Failed to parse json data: unexpected end of data.
Fix the issue by allowing the ubus query to fail with "Not found" but still
logging other failures, and by passing an empty JSON object to jsonfilter
if the interface status cache is empty.

* Change network_get_subnet6() to sensibly guess a suitable prefix
Attempt to return the first non-linklocal, non-ula range, then attempt
to return the first non-linklocal range and finally fall back to the
previous behaviour of simply returning the first found item.
* Fix network_get_ipaddrs_all()
Instead of replicating the flawed logic appending a fixed ":1" suffix
to IPv6 addresses, rely on network_get_ipaddrs() and network_get_ipaddrs6()
to build a single list of all interface addresses.
* Fix network_get_subnets6()
Instead of replicating the flawed logic appending a fixed ":1" suffix
to IPv6 addresses, rely on the ipv6-prefix-assignment.local-address
field to figure out the proper network address.

Rework the network_get_ipaddr6() and network_get_ipaddrs6() functions to
fetch the effective local IPv6 address of delegated prefix from the
"local-address" field instead of naively hardcoding ":1" as static suffix.
Fixes FS#829.

When looking for the first ipaddr also consider the current prefix just
like network_get_ipaddrs6 does. If ipv6-address was empty the function
did not return the first ipaddr even if the list was non-empty.

Switches /lib/functions/network.sh from jshn based json parsing to
jsonfilter expression while keeping the existing api.
Expensive methods like "network_find_wan" are up to 20x faster now.

- support reading inactive gateways and DNS information in
network_get_gateway(), network_get_dnsserver() and network_get_dnssearch()
by passing "true" as optional last argument
- internally cache fetched values to speed up subsequent accesses to the same
data, introduce network_flush_cache() to clear them
- add some inline function documentation
