This has become useless after refactoring; we instead ensure that the
LOG_ID_SECURITY bit isn't set in log_mask, instead of having this
additional check.

ChattyLogBuffer::FlushTo() needs an array of pid_t's to differentiate
between deduplication and spam removal chatty messages, but that won't
be useful to other log buffers, so it doesn't deserve its own entry in
the abstruct LogBuffer::FlushTo() function.
Other log buffers may need their own data stored for each reader, so
we create an interface that the reader itself owns and passes to the
log buffer. It uses a unique_ptr, such that the when the reader is
destroyed, so will this state.
FlushToState will additionally contain the start point, that it will
increment itself and the log mask, which LogBuffers can use to
efficiently keep track of the next elements that will be read during a
call to FlushTo().
Side benefit: this allows ChattyLogBufferTests to correctly report
'identical' instead of 'expired' lines the deduplication tests.
Side benefit #2: This updates LogReaderThread::start() more
aggressively, which should result in readers being disconnected less
often, particularly readers who read only a certain UID.

SimpleLogBuffer::FlushTo() attempts to find the iterator matching a
given sequence number, but the logic is wrong and will always skip one
element forward. This change fixes this and adds a test for the
situation.
This likely contributed to some test instability in the past, but was
identified because subsequent changes that track the start value
closer exacerbated this issue.

This was a typo; the enum corresponds to the result of the 'Filter'
function, not the 'FlushTo' function.
