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.

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.

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
