b28de95da4 Error handling using failure in API (#949)
This PR adresses #166
Error handling in wallet was ported to failure in https://github.com/mimblewimble/grin/pull/713
Using the same error model makes wallet code simpler and may simplify migration to Hyper.

8e26d4dbac Fix Bus Error (core dumped) when validating fast sync txhashset (#956)
This PR fixes #953 by introducing a lock for txhashet_write. It's not enough
to synchronize access to in memory data, files also needs to be protected, so
a general txhashset lock was introduced.

Improvements to orphan handling to help sync (#931)
Our chain orphans data structure now does:

* Eviction based on a max total number of orphaned blocks
* Evicts further away first, then too old
* Avoids all cloning (blocks can be big)

This allows sync to be a little more stupid, only reducing the
number of blocks it requests when orphans get nearly full.

Fixes #897

* commit

* rustfmt

* fixed it (needs a lot of cleanup)
we were not traversing all the way up to the peak if we pruned an entire tree
so rm_log and prune list were inconsistent

* multiple compact steps are working
data file not being copmacted currently (still to investigate)

* cleanup store tests

* cleanup

* cleanup up debug

* rustfmt

* take kernel offsets into account when summing kernels and outputs for full txhashset validation
validate chain state pre and post compaction

* rustfmt

* fix wallet refresh (we need block height to be refreshed on non-coinbase outputs)
otherwise we cannot spend them...

* coinbase maturity via merkle proof basically working

* ser/deser merkle proof into hex in api and wallet.dat

* cleanup

* wip - temporarily saving merkle proofs to the commit index

* assert merkle proof in store matches the rewound version
there are cases where it does not...

* commit

* commit

* can successfully rewind the output PMMR and generate a Merkle proof
need to fix the tests up now
and cleanup the code
and add docs for functions etc.

* core tests passing

* fixup chain tests using merkle proofs

* pool tests working with merkle proofs

* api tests working with merkle proof

* fix the broken comapct block hashing behavior
made nonce for short_ids explicit to help with this
