class DlogReader

DlogReaders drain debuglogs. Owners of DlogReaders are called back as
messages are pushed through the debuglog, via the Notify callback.

void Initialize (NotifyCallback * notify, void * cookie, DLog * log)Since DlogReaders typically capture containing objects via |cookie_|, they
use 2-phase initialization to avoid races in the contruction of the
DlogReader and the containing object.
The optional parameter `log` is used mainly for testing purpose. It should be left as default
for all other uses, in which case the static global DLOG will be used. If `log` takes the
default value i.e static global DLOG, it will outlive the DLogReader and hence there will be no
lifetime issues. If `log` is specified, as it would be in case of tests, the test has to
ensure that the `log` object outlives any DLogReaders associated to it.

zx_status_t Read (uint32_t flags, dlog_record_t * record, size_t * actual)Read one record out of the log and store it in |record|.
Upon success, returns ZX_OK and sets *|actual| to the record's size.

void Disconnect ()Similar to Initialize, DlogReaders are be manually stopped via |Disconnect|
to avoid reentrency issues in the DlogReader and its containing object.
Disconnect must be called before the destructor runs, if Initialize was called.
