It looks like lockfile implementation did still suffer from a race
condition. Only when creating the file with O_EXCL, file creation fails
if the file does already exist. One could use O_EXCL, but Windows
might use another flag to achieve the same. Moreover, O_EXCL doesn't
work as expected if the files are accessed over NFS.
In contrast, mkdir() is atomic in every of the mentioned cases.
Aside from using a lockdirectory, this patch also backups the current
wallet.dat contents to wallet.bck in case writing a possibly hefty
amount of JSON to the new wallet.dat fails. It is hoped that at least
one of the .bck and .dat files has usable contents in case failure.
* wip BlockMarker struct, get rid of PMMRMetadata
* use rewind to init the txhashet correctly on startup, we do not need to track pos via metadata (we have block markers), we do not need to open the txhashset with specific pos (we have rewind)
* better logging on init
* keep rewinding and validating on init, to find a good block
* use validate_roots on chain init
* Test multi kernel deaggregation
* Add aggregate without cut_through and deaggregate function
* Add deaggregate function in pool and test
* Rustfmt
* Add deaggregate_and_add_to_memory_pool
* Deaggregate regular multi kernel transaction by default
* Rustfmt
* Add error type faileddeaggregation
* Add find candidates function
* Rustfmt
* Use intersection of sets instead of for comparisons
* Rustfmt
* Removed unnecessary if
* Stricter verification with is_subset

`Async<Discard>` means "drain that will send each logging
record to an async thread, that will discard it". This means
logging record is sent to another thread for no reason.

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.
* Fix issue where we have no metadata for a block (#938)
when restarting node before initial sync completed
* Avoid double-locking on add eviction. Fixes#936

* Modifications for review comments. Move stratum test into its own file, move get_block() into its own rust module, use pool and chain only rather than the entire Miner object

* 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.
