This reduces allocs and bytes used per log entry significantly as well
as some improvement to time per log operation.
Each log driver, however, must put messages back in the pool once they
are finished with the message.

this adds new tests to test logging of long log-lines
(without newlines), and trailing log-lines.

Add a benchmark for measuring how the logger.Copier implementation
handles logged lines of sizes ranging up from 64 bytes to 256KB.

Log drivers are instantiated on a per-container basis, and passed the
container ID (along with other information) when they're initialized.
Drivers that care about that value are caching the value that they're
passed when they're initialized and using it in favor of the value
contained in Message structures that are passed to them, so the field in
Messages is unused, so we remove it.

this prevents the copier from sending messages in the buffer to the closed
driver. If the copied took longer than the timeout to drain the buffer, this
aborts the copier read loop and return back so we can cleanup resources
properly.

- 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.

Also there is aux datastructure Copier which can copy lines from streams
to Loggers
