The current default of hourly is too fast. Some services such as
DuckDuckGo return IPs from a pool based on the user's location instead
of a fixed IP address. This change prevents unnecessary writes to the
flash memory by only updating once per week.

Some users have reported that reloading dnsmasq does not always work. It
sometimes stop responding to DNS lookup requests after being reloaded.
This patch changes "safe-search-maintenance" so that it restarts dnsmasq
instead of reloading it.

Ensure that the best available IP is always used for all supported
safe-search providers. This is accomplished by periodically checking
DNS for the most recent list of IP addresses associated with each
provider.

If safe search is built directly into an image, the /etc/config/dhcp
file will have multiple entries added to it after using sysupgrade
for the nth time (2 or more sysupgrade cycles).
In /etc/config/dhcp, this bug creates duplicate entries like this:
config dnsmasq
list addnhosts '/etc/safe-search/enabled'
list addnhosts '/etc/safe-search/enabled'
This patch ensures that safe search only registers itself one time.

This package forces the use of Google and Bing safe search by default.
It does this by adding hosts files for dnsmasq to use. These hosts replace the
normal IP addresses for Google and Bing with addresses that force safe
search to be turned on all the time.
Google and Bing Safe Search are suitable for most businesses, schools, and
families who wish to block adult content. This package also offers
YouTube's restricted and 'restricted moderate' via a configuration
option. The reason that this is not enabled is that it is probably more
suitable for children rather than a wide audience.
This package is designed so that other services that offer safe search can be
added easily in the future.
