use maxDialCacheSize constant
rename functions and container
+ dnsfilter: cache IP addresses of safebrowsing and parental control servers
Before this patch we could exit the process without waiting for
file writing task to complete.
As a result a file could become corrupted or a large chunk of data
could be missing.
Now the main thread either waits until file writing task completes
or it writes log buffer to file itself.
* dnsforward: prioritize host files over null filter
* dnsforward, config: adjust setting variable to blocking_mode
* dnsforward: use net.IPv4zero for null IP

Close#732
* commit 'c4e67690f4fcceb055cbea73610b5974855db96f':
* dnsfilter: don't use global variable for custom resolver function
- dnsfilter: prevent recursion when both parental control and safebrowsing are enabled
* commit '528c1a72cac331f08de5fdee4538529c70dff1bb':
- use 127.0.0.1 as a resolver address when DNS binding address is 0.0.0.0
- app: don't print filter update error messages on first launch before DNS server is set up
Before this patch we couldn't receive incoming DHCP packets.
Now we bind() to 0.0.0.0 and set the required network interface
using SO_BINDTODEVICE option.
As an improvement, we now wait until a reply to our request is
received and skip all unknown packets.
