27220ecc6b Move timeutils functions to the only places where they are used.
- Move time json marshaling to the jsonlog package: this is a docker
  internal hack that we should not promote as a library.
- Move Timestamp encoding/decoding functions to the API types: This is
  only used there. It could be a standalone library but I don't this
it's worth having a separated repo for this. It could introduce more
complexity than it solves.

c57faa91e2 Ensure reader position is at the end after tailing
After tailing a file, if the number of lines requested is > the number
of lines in the file, this would cause a json unmarshalling error to
occur when we later try to go follow the file.
So brute force set it to the end if any tailing occurred.

There is potential that there could be some missing log messages if logs
are being written very quickly, however I was not able to make this
happen even with `while true; do echo hello; done`, so this is probably
acceptable.

While testing this I also found a panic in LogWatcher.Close can be
called twice due to a race. Fix channel close to only close when there
has been no signal to the channel.

3a8728b431 daemon: Logging drivers refactoring
- noplog driver pkg for '--log-driver=none' (null object pattern)
- centralized factory for log drivers (instead of case/switch)
- logging drivers registers themselves to factory upon import
  (easy plug/unplug of drivers in daemon/logdrivers.go)
- daemon now doesn't start with an invalid log driver
- Name() method of loggers is actually now their cli names (made it useful)
- generalized Read() logic, made it unsupported except json-file (preserves
  existing behavior)

Spotted some duplication code around processing of legacy json-file
format, didn't touch that and refactored in both places.
