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.
Breaking changes are:
opcode::All::from_u8 is now From<u8>
script::Builder::from_vec is now From<Vec<u8>>
script::Script::from_vec is now From<Vec<u8>>
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.
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.
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.
This is a massive simplification, fixes a couple endianness bugs (though
not all of them I don't think), should give a speedup, gets rid of the
`serialize_iter` crap.
I think this is what I want to do for everything json-visible...perhaps
I will not be able to keep the macro for it though, since there are
some clever variations on it (e.g. blocks should have their header's
hash as a field, txes should appear as txids unless vebose output is
requested, etc.)
