The reason behind this drastic move was that sometimes a lock needs to
persist across multiple calls to a DataStore. For example, when a PATCH
request is received, following behaviour is wanted:
* Obtain lock (LockUpload)
* Get offset, size etc (GetInfo)
* Write data (WriteChunk)
* Release lock (UnlockUpload)
However, before this change, the lock would be release and then obtained again
after the GetInfo and before the WriteChunk call. This resulted in an
inefficient resource usage and even a possible race condition.
The effects of this change was:
* FileLocker is now directly integrated into FileStore and not sperarated
* LockingStore and the entire package has been removed
* MemoryLocker has been moved into its very own package
* expose tusd.DataStore and extracted FileStore
* use pat for routing
* allow absolute BasePaths
* requires StripPrefix
* add support for 1.0 core
* update date in license
