504b67c186 ByteUtils: check range of values supplied to write helpers for the Java Unsigned Integer API 
These checks uncovered various uses of illegal values (now fixed).
They should help this won't happen in future.

`originallyEncodedSize` is not considered on purpose, because it is only

f3c4b5fcf4 BloomFilter: use signed integer for the nonce (nTweak) 
It's arbitrary data and we're not supposed to do math on it, so it's
safe to use a signed Java `int`.

Also use `new Random().nextInt()` to generate the nonce. We were
previously generating a random double, multiplying by `Long.MAX_VALUE`
and then truncating the low 32-bits of the long. Using `.nextInt()`
might actually generate MORE randomness since there will be no truncation.

48f4d143f3 FeeFilterMessage: disallow negative fee rate 
Fee rates are signed "int64_t", according to BIP-133. The spec doesn't
mention, but it goes without saying that negative fee rates make no
sense.

31d98af8f6 TransactionOutput: disallow negative values 
Negative values obviously make no sense, except for `-1` which is
used as a sentinel value when calculating `SIGHASH_SINGLE` signatures,
so unfortunately we have to allow that here.

b8f77abe62 SeedPeers: fix conversion of int representation of IPv4 addresses to InetAddress 
Usage of `writeUint32LE()` is wrong on two counts:

* `InetAddress.getByAddress()` expects big-endian values, and the method
  above encodes as little-endian.
* Java int is signed, even if the Java hex literal appears unsigned. The
  above method expects unsigned values.

So we add the previously missing `writeInt32BE()` to ByteUtils and use it.

be12c389f3 Message: parse the original ByteBuffer, rather than a copy of it 
This has the advantage of using the read position contained in
`ByteBuffer`, so we remove our `offset` and `cursor` fields.

32837798c1 Message: remove length and optimalEncodingMessageSize fields 
This does away with a lot of updating the fields while parsing and
mutating the data.

`getMessageSize()` now returns the length of the data as
serialized by `bitcoinSerializeToStream()`, which can be different
from the length of an original payload.

The default implementation of `getMessageSize()` is not performant
enough for all usecases, to it is overridden in strategic subclasses
to calculate the size in a much more efficient way.
