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.

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.

6cebf39723 Damn ugly HTTP interface "equivalent" for machi_cr_client.erl basic API 
This goes to show that mixing implementation and protocol and API
and lots of other stuff ... is cool for the quick hack to do one thing
but really sucks when trying to do more than one thing.

* Proof-of-concept only: add HTTP/1.0'ish 'PUT' interface to be the
rough equivalent of machi_cr_client:append_chunk/3
* Proof-of-concept only: add HTTP/1.0'ish 'GET' interface to be the
rough equivalent of machi_cr_client:read_chunk/4

Example use: `append_chunk`

    % curl http://127.0.0.1:4444/foo -0 -T /etc/hosts -v
    * Hostname was NOT found in DNS cache
    *   Trying 127.0.0.1...
    * Connected to 127.0.0.1 (127.0.0.1) port 4444 (#0)
    > PUT /foo HTTP/1.0
    > User-Agent: curl/7.37.1
    > Host: 127.0.0.1:4444
