Transaction(txbuf);
Rather than having to do this:

make receivePubkey compatible with dark wallet
...
I had been using this formula for the receiveKeypair:
scanKeypair + payloadKeypair + sharedKeypair
However, Dark Wallet uses this formula:
payloadKeypair + sharedKeypair
It is not actually necessary to add the scanKeypair in order to have all the
features of stealth addresses, at least as far as I can tell. So in order to
bring my implementation closer to Dark Wallet's, I have removed the scanKeypair
from this calculation.

understanding of Varints in the BufferReader and BufferWriter classes. However,

track of the raw buffer that is read in from a buffer.

fix bug where you can't use isForMe without payloadKeypair

It should be possible to check to see if a message isForMe with only the
scanKeypair, and not the payloadKeypair. There was a bug where only the
scanKeypair was being used to produce the receiveKeypair, but this was a
mistake. Both the scanPubkey and payloadPubkey should be necessary to produce
the receivePubkey, and both the scanPrivkey and payloadPrivkey should be
necessary to produce the receivePrivkey. If an online computer has only the
public keys of both (and the scanPrivkey), then that is good enough to check
for isForMe.

preserve claimed length and op code
...
When parsing OP_PUSHDATAX commands, the the length of data might not require
the size integer of OP_PUSHDATAX. For instance, you might write 1 byte, and yet
use OP_PUSHDATA4. We need to record which OP_PUSHDATAX was used so that when we
write the buffer back out, we can write the same one. Also, the claimed length
may be different. For instance, we may OP_PUSHDATA of length 100 to the stack,
but there may only be 50 bytes left in the script. In that case, buf.length and
chunk.len will be different. I'm not sure if that would be considered a valid
script, but in any case, for script analysis, we need both values.
