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.

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.

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.

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.
