In the future, we'll want to be able to write to outputs that are not
necessarily a libsysutils SocketClient, for example host tests of
LogBuffer. Therefore, we add a LogWriter class to be used instead of
SocketClient.

We may use different implementations of LogBuffer in the future, so we
make it interface and create a concrete ChattyLogBuffer class that
implements it.

There's still plenty of work that can be done here, particularly
re-doing the locking so each LogReaderThread does not mutually exclude
the others, but that's out of the scope here.
This change primarily removes the public 'mTimes' from LogBuffer and
creates a new LogReaderList class instead. It would have merged this
into LogReader, but that creates a circular dependency.
This change also removes the need to reference LogReader or
LogReaderList from LogAudit, LogKLog, and LogListener, instead relying
on LogBuffer()::log() to call LogReaderList::NotifyNewLog().

1) We can use real member functions with std::thread and
std::function, so use those instead of the 'me' pointer.
2) Don't expose member variables directly.
3) Rename and document member variables, since all of their references
are being touched anyway.

LogTimes has evolved from being simply a store of the last timestamp
that each reader has read to being a class representing an individual
reader thread, including the thread function, so name it
appropriately.
