apf: Add counters for dropped / passed packets
ApfFilter maintains separate counters for each reason why a packet was
passed or dropped by the filter logic.
There's also a total which should match the individual counters,
*unless* the APF interpreter aborted execution early due to an illegal
instruction or an out-of-bounds access.
Test: both on APFv2 and APFv4-capable device:
runtest -x tests/net/java/android/net/ip/IpClientTest.java
runtest -x tests/net/java/android/net/apf/ApfTest.java

Relax APF version check in ApfGenerator
Instead of requiring an *exact* version, we now require a minimum
version. This is necessary if we wish to upgrade the APF interpreter in
vendor firmware independently of the framework code. Adding new opcodes
without changing the semantics of the old ones is always possible and
usually easy, so we can at least have a backwards-compatibility horizon
wider than a single version.

Avoid APF JNEBS instruction with R1 as it doesn't work
APF version 2 and prior versions fail to execute JNEBS with R1 argument.
The APF interpreter tries to use R1's value as the number of bytes to
compare, as well as the offset within the packet to compare at.
This change makes ApfFilter avoid using this and makes the APF generator
throw if this is used. This was limiting the IPv4 filter, causing it to
only drop multicast (when multicast filtering was enabled), rather than
a wider range of broadcast packets.
