Andrew Poelstra 20ce3721b7 Fix for upstream 2014-09-04 19:06:52 -05:00
Andrew Poelstra c25862a107 Change UtxoSet to use full TXID as key
Sorry, this is needed to enable proper txid/vout lookups for the address index.
This means any users of wizards-wallet need to rebuild their utxo sets, and
will also mean an increase in RAM usage.

Andrew Poelstra 9d283150c9 Fix GT/LT/GTEQ/LTEQ handling to not compare bools
I was trying to do something clever by making sure that the numeric
bounds were consistent with whatever ordering relation we were checking,
AND that the boolean values were also consistent...this is Wrong is the
case of negative numbers, and pointless anyway since I recently fixed
`set_bool_value`, `set_num_lo` and `set_num_hi` to update both numeric
and boolean information if possible, so they will always contain the
same info.

Andrew Poelstra d880bd1ccc Ensure execution state stack is empty at the start
We had a single `true` on the execution state stack, which would
allow scripts to have one more OP_ENDIF than they are allowed.

Andrew Poelstra 340b569c73 Add much more agressive provably-false checker
Now unspendable outs are determined by attempting to create a minimal
satisfying input script. If this can't be done, the output is unspendable.
(Unfortunately this "minimal satisfying script" is not (yet) something
that can be shown to the user, since it is more a bundle of constraints
than actual data pushes.)

Current limitations:
  - OP_ADD and friends mean the checker gives the script a free pass.
    There is no fundamental reason for this, I just didn't get to it
    yet.

  - Pubkeys are checked for DER encoding but signatures aren't. This
    is because secp256k1 exposes a method for pubkeys, but not one
    for sigs :). Signatures are loosely length checked.

Andrew Poelstra 6bf553c6fe Add BIP32 key support; unify array newtyping; improve base58 trait
Sorry for so many things in one commit ... it was an iterative
process depending as I worked on BIP32 to get the other stuff
working. (And I was too lazy to separate it out after the fact.)

A breaking change by the array newtyping is that Show for Sha256dHash
now outputs the slice Show. You have to use `{:x}` to get the old hex
output.

in future.
