2d070bf1e3 Minor refactoring + add demo/exploratory time measurement code
%% Demo/exploratory hackery to check relative speeds of dealing with
%% checksum data in different ways.
%%
%% Summary:
%%
%% * Use compact binary encoding, with 1 byte header for entry length.
%%     * Because the hex-style code is *far* slower just for enc & dec ops.
%%     * For 1M entries of enc+dec: 0.215 sec vs. 15.5 sec.
%% * File sorter when sorting binaries as-is is only 30-40% slower
%%   than an in-memory split (of huge binary emulated by file:read_file()
%%   "big slurp") and sort of the same as-is sortable binaries.
%% * File sorter slows by a factor of about 2.5 if {order, fun compare/2}
%%   function must be used, i.e. because the checksum entry lengths differ.
%% * File sorter + {order, fun compare/2} is still *far* faster than external
%%   sort by OS X's sort(1) of sortable ASCII hex-style:
%%   4.5 sec vs. 21 sec.
%% * File sorter {order, fun compare/2} is faster than in-memory sort
%%   of order-friendly 3-tuple-style: 4.5 sec vs. 15 sec.

d9694a992a Alright, use term_to_binary() for opaque/sexp-style encoding, only 15x slower.
machi_flu1_test: timing_pb_encoding_test_... speed factor=15.12 [2.678 s] ok

2763b16ca2 timing_pb_encoding_test_... speed factor=35.95 [2.730 s] ok
So, the PB style encoding of the Mpb_LL_WriteProjectionReq message
is about 35-36 times slower than using Erlang's term_to_binary()
and binary_to_term().  {sigh}

5d8b648a24 All projection store protocol operations are now using Protocol Buffers!
So, there's some cheating going on, because some of the parts of
the #projection_v1{} and #p_srvr{} records aren't fully specified.
Those parts are being specified as "opaque" in the field names, e.g.

    optional bytes opaque_flap = 10;
    optional bytes opaque_inner = 11;
    required bytes opaque_dbg = 12;
    required bytes opaque_dbg2 = 13;

The serialization that's being used is erlang term sexprs.  That isn't
portable.  So if/when we really need to deal with a non-Erlang
language, we'll have to straighten this out further.
