* add client side block filters with code from murmel. use siphash from bitcoin_hashes pass Bitcoin Core tests upgrade to bitcoin_hashes 0.7
* add filter.filter_id() test use BlockFilter directly
* fixed edge cases of matching empty query sets or or using empty filter
This creates two ways to encode an empty transaction; we should use only the
Segwit-enabled one because that's what we do for 0-input non-0-output transactions.
- Move network::encodable::* to consensus::encode::*
- Rename Consensus{En,De}codable to {En,De}codable (now under
consensus::encode)
- Move network::serialize::Error to consensus::encode::Error
- Remove Raw{En,De}coder, implement {En,De}coder for T: {Write,Read}
instead
- Move network::serialize::Simple{En,De}coder to
consensus::encode::{En,De}coder
- Rename util::Error::Serialize to util::Error::Encode
- Modify comments to refer to new names
- Modify files to refer to new names
- Expose {En,De}cod{able,er}, {de,}serialize, Params
- Do not return Result for serialize{,_hex} as serializing to a Vec
should never fail
- Add serialize::Error::ParseFailed(&'static str) variant for
serialization errors without context
- Add appropriate variants to replace network::Error::Detail for
serialization error with context
- Remove error method from SimpleDecoders
- Separate serialize::Error and network::Error from util::Error
- Remove unneeded propagate_err and consume_err
- Change fuzzing code to ignore Err type
Previously this structure was unused, it's now being used by the `TxIn`
structure to simplify the code a little bit and avoid confusions. Also
the rust-lightning source code has an `OutPoint` similar to this one
but with the `vout` index as an `u16` to avoid unsafe conversions.
I've added to new methods to `OutPoint`:
- `null`: Creates a new "null" `OutPoint`.
- `is_null`: Checks if the given `OutPoint` is null.

The `serde_struct_impl!` macro has been modified to be compatible
with the serde 1.0 crate, we use this macro and not the `serde_derive`
crate because the latter doesn't support Rust 1.14.0 which is shipped
on Debian stable and we should remain compatible with it.
Two new features were added:
- "serde": enables serialization/deserialization for common types, it pulls
the serde 1.0 dependency.
- "serde-decimal": enables serialization/deserialization for `UDecimal`/`Decimal`,
this pulls the strason 0.4 depdendency and the serde 1.0 dependency.

Addresses #96.
Turns out it was being used for hex encoding/decoding, so replaced that with the `hex` crate.
i chose to import the `decode` method as:
```
use hex::decode as hex_decode
```
so that it is clear to the reader what is being decoded when it is called. "decode" is such a generic sounding function name that it would get confusing otherwise.
This is a rather large breaking API change, but is significantly
more sensible. In the "do not allow internal representation to
represent an invalid state" category, this ensures that witness
cannot have an length other than the number of inputs. Further,
it reduces vec propagation, which may help performance in some
cases by reducing allocs. Fianlly, this just makes more sense (tm).
Witness are a per-input field like the scriptSig, placing them
outside of the TxIn is just where they are serialized, not where
they logically belong.
This is needed to for a sane BIP143 implementation. Should be exactly equivalent to
serializing data into a vector then hashing that vector for all types.
This code was unmaintained, is unlikely to work on the majority of systems
(since it holds the whole utxoset in RAM, and not in a terribly efficient
manner), and has a dependency on `eventual` which has been broken for a
long time.
The library no longer compiles on nightly because of this, and without any
known usecases for `UtxoSet`, nor good ability to test it, I'm simply
removing the code.
I recommend anyone who cares about this extracts the code from the previous
commit and creates a new crate. It should be more featureful anyway, e.g.
support a backing store.
This is just a convenience type for the (txid, vout) pairs that get produced
a lot in Bitcoin code. To the best of my knowledge there is nowhere this can
be used in the actual library (in particular, TxOutRef.index is a usize for
convenience while TxIn.prev_index is a u32 for correct consensus encoding,
so there is not redundancy here).
