When statsd pulls data from StatsCompanionService, the data is put into
log_msg format on java side and expanded into LogEvent on cpp side.
There is a lot of dependency on log_msg and liblog to add new types.
There is pending bug to rewrite thta part of the code in statsd to
completely rid the legacy of logd and liblog. But that may not happen
soon.
Now we can support new storage type.
Also no need to specify number of fields in StatsLogEventWrapper cstr,
which is a source of bug in P.

Allows a uid that uploads a statsd config to additionally
register a BroadcastSubscriber with statsd. If statsd
detects an anomaly (according to the config's Alert),
statsd can inform a BroadcastSubscriber provided in the config.
The config uses a subscriberId (just an int) to identify the
BroadcastSubscriber. It then uses StatsManager.setBroadcastSubscriber
to associate that subscriberId with a given PendingIntent.
Then, when the anomaly is detected, statsd sends a broadcast
using that PendingIntent, alerting whoever was specified by
the config/setBroadcastSubscriber.

This patch adds an overload to DropBoxManager::addFile() which accepts
an already-opened file as a file descriptor. This avoids the need for
clients to create a filesystem-visible file when uploading data to
DropBox.
Test: Tested with perfetto using https://android-review.googlesource.com/c/platform/external/perfetto/+/587674

Previously, pulled data was returned as a string. We instead
return the data as an array of StatsLogEventWrapper, which encodes
using the binary-encoded format liblog uses. StatsD uses the same
parsing as for pushed events to convert these. This CL also fixes
the parsing of log_msg since the strings were previously emptied
before we had a chance to read the values.
Note that the cpp-aidl can't support List of Parcelable, so we
have to return the results as an array.
Test: Manual using the new command in StatsService to print results.
Also created a new unit-test by creating a dummy pull code of -1,
but this test is deleted since it required creating a fake output in
StatsCompanionService.
