* Added support for ingesting sst files using the SstFileWriter. (#37)
* Create ColFamilyReadOnly and ColFamilyReadWrite types for using a specific column family.
* Use inline pragma for small procs and add lock to RocksDbRef type close to prevent double free.

* Added tests for sstfilewriter.
* Documentation minor improvements.
* Made del return a bool, and added clear.
What I've done here feels very awkward. Maybe I'm missing something,
but it looks to me like RocksDB doesn't support these operations in
any natural way.
These changes were made in order to get our implementation of
KvStoreRef for RocksDB working again after these changes to the
KvStoreRef interface:
8f0ae55353
I don't really recommend merging this; I think I'd prefer to just stop
trying to use this common KvStoreRef interface.
Still, if we do want to keep the common interface, I think this commit
will work well enough.
* Updated the tests to expect del to return a bool too.
* Leave the new `clear` operation unimplemented.
- added "--threads:on"
- fixed the Nim API tests and moved them to unittest
- added copyright header
- combined the 2 test file into tests/all.nim and set that as the
Nimble test target
- had Travis run that
- new "tempfile" dependency to create proper tempfiles + deleting them
at the end
- copied the error string to RocksDBResult
* error is a pointer to a cstring that the API will allocate on error
* if an error is returned, it must be free'd
* note missing tests for when error happens
The API is still very basic and suffering from multiple Nim issues
that will be resolved in the near future:
* destructors will handle the resource cleanup better
* converter concepts will enable a wider range of possible types
to be used as keys and values.
The API currently uses an ErrorResult type to communicate errors,
but RocksDB doesn't seem to have many recoverable failure modes
and I anticipate that the API will be migrated to use exceptions
once we get a bit more experience with RocksDB.
The C interface file was moved to a separate directory to make
nimble happy (`nimble check`).
