appendStringRepresentationOfBitMaskToStringBuilder to this
class. It also moves some other NetworkCapabilitiesUtils
methods that are better homed in this new class.

Revert "[ST02.1] Add TYPE_CNAME constant to DnsResolver"
Revert submission 1387135-st02

modules does not interact well with current module release process
Reverted Changes:

EthernetTetheringTest has parseMapKeyValue that decodes the string
encoded by BpfDump#toBase64EncodedString
Upcoming CL also wants to decode the encoded string.
So this CL renames parseMapKeyValue to fromBase64EncodedString and moves

Throwable could be used as a type argument to catch(), but it would
possibly never be caught, because the method only catches Exception.
Notably, junit assertions fail with AssertionError, which is not a
subclass of Exception. Due to that, tests or utilities like
DeviceConfigRule that have failing assertions in catch() would not
run the subsequent cleanup steps.

NetlinkEvent#parse relies on message-specific classes to parse
the payload of the message. If these classes do not consume the
entire message, parse does not advance to the end of the
message. This means that any code that loops over a ByteBuffer
parsing messages one at a time (e.g., NetlinkMonitor) will think
that there is still a message left to parse, and will attempt
to parse the remainder of the message as a new netlink message.
This is obviously incorrect for any buffer that contains more
than one netlink message.

Currently the netlink parsing code doesn't advance to the end of message
if it doesn't consume the entire message, that results in the remaining
attributes will be considered as a new netlink message, parsing the
attributes will fail and return null. Have a testcase to verify this case.

Change #selectBestRoute to account for non-unicast routes.
Method is used to detect if the address is reachable and via which
gateway. From that point of view, address being best matched by
a non-unicast route is equivalent to the address not being matched by
any route at all.
Method's implementation is adjusted to reflect the above logic. This
allows to avoid changing method's usages.

Thankfully this is not actually a security vulnerability, because
the sign bit just gets set, and the conversion to long performs
sign extension. Still, it would break when adding one with 32.
To avoid repeats of this same mistake, convert the creation of
masks to using a function in a way that makes it impossible.
