Andrew Kelley 06b44a0afa update git fetching logic to new reader/writer API
- flatten std.crypto.hash.Sha1 and give it a writable interface that
  optimizes splats
- flatten std.hash.crc and give it a writable interface that optimizes
  splats
- remove old writer impls from std.crypto
- add fs.File.Writer.moveToReader
- add fs.File.Writer.seekTo
- add std.io.Reader.Hashed and std.io.Writer.Hashed which are
  passthrough streams. Instead of passing through to null writer, use
  the writable interface implemented directly on hashers which doesn't
  have to account for passing through the data.
- add std.io.BufferedWriter.writeSplatAll
