20516da9bc Merge libstatspush_compat and libstatssocket_q
This cleanup makes it clear that there are only two acceptable ways of
logging to the socket: either through libstatspush_compat or
libstatssocket (which will soon be renamed to libstatspush).

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

a38d5a6fd6 Simplified stats_event.c; exposed getter methods
Simplifications/changes:
(1) We remove the bufPos field and track the end of the buffer using
    only the size field.
(2) We rename put_<type>() functions to append_<type>() to signify that the
    value will be placed at the end of the buffer. We also move the
    increment of event->size to within the append_<type>() functions;
    this improves readability of the write_<type>() functions.
(3) We immediately write the timestamp and atom id to the buffer in
    order to simplify stats_event_build().
(4) We never check for null pointers; checking for null pointers
    delays errors and obfuscates the root problem.
(5) We change the the annotationId and numPairs parameters to be
    uint8_t's. This helps signify to clients that these values must fit
    in 1 byte.
(6) Clients no longer have to pass in the length of strings. Instead, we
    expect them to pass in null-terminated strings, and we will
    calculate the length outselves using strnlen.

3822e61d7b General cleanup; add support for key-value pairs
Encoding of key-value pairs follows strategy described in
go/statsd-socket-doc.

Fixed bug where timestamp and atom id were not contributing to the
number of fields in the buffer.

Note: Similar to ag/9603344, which was abandoned because of git rebasing
issues.

4d1deed139 Remove a redundant check in statsd socket code.
The original liblog code has this additional check because there may be multiple writers registered,
there is a for-loop and the retVal is set to be the FIRST error. Statsd doesn't need it because it
 only has one writer.
