There is still a lot of work to do modernizing the library, but the code
compiles cleanly with all unit tests passing now. Probably not much can
be done now until wizards-wallet is in better shape and the library is
actually in use.
Work is stalled on some other library work (to give better lifetime
requirements on `eventual::Future` and avoid some unsafety), so
committing here.
There are only three errors left in this round :)
Also all the indenting is done, so there should be no more massive
rewrite commits. Depending how invasive the lifetime-error fixes
are, I may even be able to do sanely sized commits from here on.
27 files changed, 3944 insertions(+), 3812 deletions(-) :} I've
started doing whitespace changes as well, I want everything to
be 4-space tabs from now on.
BTW after all this is done I'm gonna indent the entire codebase...
so `git blame` is gonna be totally broken anyway, hence my
capricious cadence of commits.
Will take some experimentation to see if this is what I want the API
to be, if the memory usage is acceptable, etc.
This will force a total reindex for wizards-wallet users.

Reconnecting an existing socket simply was not working; the Rust socket
did not expose any methods for reconnection, so I simply tried calling
connect() again. As near as I can tell, this was a no-op --- which makes
sense because both the sending and receiving threads had their own copy
of the Socket, and it's not clear what the synchronization behaviour
should have been.
Instead if the connection fails, we relay this information to the main
thread, wait for an acknowledgement, then simply destroy the listening
thread. The caller can then simply call `start()` again.
`verify` cannot handle illegally padded signatures because it takes an object
of type `Signature`, which is a fixed-size type. This should have been part
of the previous commit --- an important lesson about running the unit tests
before every push!
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.
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.
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.
