This allows much of the read logic to be shared for other things,
especially for the new log driver proposed in
https://github.com/moby/moby/issues/33475
The only logic for reads in the json logger is around decoding log
messages, which gets passed into the log file object.
This also helps with implementing compression as it allows us to
simplify locking strategies.

Make the `*RotateFileWriter` specifically about writing
`logger.Message`'s, which is what it's used for.
This allows for future changes where the log writer can cache details
about log entries such as (e.g.) the timestamps included in a particular
log file, which can be used to optimize reads.

Log drivers may have an internal buffer size that can be accommodated
by the copier as it is more effective to buffer and send fewer though
larger messages that the log driver can consume.
This eliminates the need for Partial handling for drivers that do not
support the concept (ie: awslogs, which can only have events up to
service limits).

Use strongly typed errors to set HTTP status codes.
Error interfaces are defined in the api/errors package and errors
returned from controllers are checked against these interfaces.
Errors can be wraeped in a pkg/errors.Causer, as long as somewhere in the
line of causes one of the interfaces is implemented. The special error
interfaces take precedence over Causer, meaning if both Causer and one
of the new error interfaces are implemented, the Causer is not
traversed.

- Remove usage of it from `profiles/apparmor` where it wasn't required
- Move the package to `daemon/logger/templates` where it's only used

If you want to use the advanced query in logentries
logging in json is very useful. If you do not need
the advanced information with
--log-opt line-only=true just logs the payload

Having a map per log entry seemed heavier than necessary. These
attributes end up being sorted and serialized, so storing them in a map
doesn't add anything (there's no random access element). In SwarmKit,
they originate as a slice, so there's an unnecessary conversion to a map
and back.
This also fixes the sort comparator, which used to inefficiently split
the string on each comparison.

Before this patch, a log reader is able to block all log writes
indefinitely (and other operations) by simply opening the log stream and
not consuming all the messages.
The reason for this is we protect the read stream from corruption by
ensuring there are no new writes while the log stream is consumed (and
caught up with the live entries).
We can get around this issue because log files are append only, so we
can limit reads to only the section of the file that was written to when
the log stream was first requested.
Now logs are only blocked until all files are opened, rather than
streamed to the client.

When closing the log-file, and the file is already
closed, there's no need to log an error.
This patch adds a `closed` boolean to check if the
file was closed, and if so, skip closing the file.
This prevents errors like this being logged:
level=error msg="Error closing logger: invalid argument"
