chunker: implementation + required fstest patch

Browse Source 
Note: chunker implements many irrelevant methods (UserInfo, Disconnect etc),
but they are required by TestIntegration/FsCheckWrap and cannot be removed.

Dropped API methods: MergeDirs DirCacheFlush PublicLink UserInfo Disconnect OpenWriterAt

Meta formats:
- renamed old simplejson format to wdmrcompat.
- new simplejson format supports hash sums and verification of chunk size/count.

Change list:
- split-chunking overlay for mailru
- add to all
- fix linter errors
- fix integration tests
- support chunks without meta object
- fix package paths
- propagate context
- fix formatting
- implement new required wrapper interfaces
- also test large file uploads
- simplify options
- user friendly name pattern
- set default chunk size 2G
- fix building with golang 1.9
- fix ci/cd on a separate branch
- fix updated object name (SyncUTFNorm failed)
- fix panic in Box overlay
- workaround: Box rename failed if name taken
- enhance comments in unit test
- fix formatting
- embed wrapped remote rather than inherit
- require wrapped remote to support move (or copy)
- implement 3 (keep fstest)
- drop irrelevant file system interfaces
- factor out Object.mainChunk
- refactor TestLargeUpload as InternalTest
- add unit test for chunk name formats
- new improved simplejson meta format
- tricky case in test FsIsFile (fix+ignore)
- remove debugging print
- hide temporary objects from listings
- fix bugs in chunking reader:
  - return EOF immediately when all data is sent
  - handle case when wrapped remote puts by hash (bug detected by TestRcat)
- chunked file hashing (feature)
- server-side copy across configs (feature)
- robust cleanup of temporary chunks in Put
- linear download strategy (no read-ahead, feature)
- fix unexpected EOF in the box multipart uploader
- throw error if destination ignores data
