8056dd129a Support ERROR_ATOM_ID_INVALID_POSITION
Originally, the native implementation would discard everything clients
wrote to the buffer before the setAtomId call. Thus, the atom id was
always placed in the "correct position." However, for consistency with
the Java implementation, we now allow write calls before setAtomId to
occur and log an error in that case.

e712eed24c Support atom-level annotations within AStatsEvent
Refactors implementation details to allow for atom-level annotations.
This CL does not change the API surface. addBoolAnnotation and
addInt32Annotation work for both atom-level and proto field annotations.

Create a function to overwrite timestamp for LogEvent tests. This
function is not exposed outside of the APEX.

b173a95ae8 Fix native stats_event logging
pass the byte array pointer; not the reference to the pointer.

Also turn on new socket protocol.

a8fd39d83f Expose libstatspull as a stable C API
Libstatspull will ship as a part of the statsd apex in R.

Also update libstatssocket to have version 30 to align with api level,
as per native api council feedback.

Change both libraries to use NDK style naming conventions (AStatsEvent,
AStatsManager), and remove unneeded APIs in libstatssocket.

Remove KeyValuePairs from libstatssocket. KeyValuePairs will not be
supported in native code.

79dd3eaa87 Improve stats_event memory usage
We now truncate the buffer to the appropriate length when clients call
stats_event_build().

Benchmarking tests indicate that truncating the buffer to the
appropriate length increases the cost clients pay to write to the socket
by 2%. This is negligible enough that I decided to truncate the buffer
for both pushed and pulled atoms in order to simplify the API.

926fa88c35 StatsEventCompat
StatsEventCompat is a wrapper library that toggles between the old
logging scheme and the new logging scheme. It was designed particularly
for the DNS Resolver module and should not be used by others.

We will merge libstatspush_compat and libstatssocket_q in a future CL.

962cc23b9f Create stats_buffer_writer
Move iovec* construction and noteLogLoss from stats_event_list to
stats_buffer_writer.h.
Expose write_buffer_to_statsd that takes in a byte array and writes
it to the statsd socket. Currently exposed for StatsLog.write JNI call.

This change also allows getting rid of stats_event_list once all clients
have migrated to stats_event
