B took on the value of C. This was not only needlessly complex
but also made it difficult to implement "safe" iteration
that lets one remove the value being iterated on, which is
going to be implemented in a subsequent patch.

dlog_logger: QoS contained by aggregation
The server struct in dlog_logger now contains a pointer
to the QoS module struct (aggregation) instead of being
a member field (composition).
This lets multiple server structs share the same QoS module.

dlog_logger: lazy poll only for Logger backend
The delay makes sense for Android Logger because it only reads logs
from an "external" (from the daemon's PoV) storage so they aren't
going anywhere, and it's good not to waste resources trying to read
them at boot time.
Meanwhile for the Pipe backend it is important for the daemon to
actively listen to clients who might be trying to write logs, since
in that case the daemon is the storage (so logs need to be written
immediately, for example for crash report reasons) and also the
implementation requires it (since pipes otherwise get clogged).

Ensure the timestamp always increases in zero-copy libdlog
The kernel guarantees that it won't decrease, but if function is
executed in quick repetition it might happen that we get the same value
twice in a row. This is unacceptable, since the timestamp is the only
thing we rely on in order to sort the messages.
This mirrors a similar change in the kernel module, see 282866. In the
kernel the issue has been more visible since the kernel might split the
messages in a quite arbitrary way. In userspace the issue has been
harder to notice, but with Marek's changes increasing the performance it
has become more urgent.
