Copybara transforms code slightly different than MOE. One
example is the TODO username stripping where Copybara
produces different results than MOE did. This change
moves the Copybara versions of comments to the public
repository.
Note: These changes didn't originate in cl/247950252.

A previous CL removed use of Google-specific random number generating
functionality, such as ACMRandom, and used the C++11 standard library
instead. The CL used std::uniform_distribution<uint8_t> to generate
random bytes, which seems to be unsupported by the standard [1, 2].
For better or for worse, our toolchain does not complain. However,
Visual Studio errors out with "invalid template argument for
uniform_int_distribution: N4659 29.6.1.1 [rand.req.genl]/1e requires one
of short, int, long, long long, unsigned short, unsigned int, unsigned
long, or unsigned long long".
This CL replaces std::uniform_distribution<uint8_t> with
std::uniform_distribution<int>(0, 255) and appropriate static_cast<>s.

An earlier CL introduced absl::Uniform, which is not yet open sourced,
and therefore unavailable in the open source build.
This CL removes absl::Uniform and ACMRandom in favor of equivalent C++11
standard random generators. Abseil promises to be faster than the
standard library, but we can afford a speed hit in tests in return for
an easier open sourcing story.
would incorrectly accept some invalid varints that the other path would not,
causing potential CHECK-failures if the unit test were run with
--write_uncompressed and a corrupted input file.

automatically together with the other tests, and also removes the stray
function ComputeTable() (which was never referenced by anything else
in the open-source version, causing compiler warnings for some)
out of the core library.
Fixes public issue 96.

This code was not compiling under Visual Studio 2013 with warnings being treated
as errors. Specifically:
1. Changed int -> size_t to eliminate signed/unsigned mismatch warning.
2. Added some missing return values to functions.
3. Inserting character instead of integer literals into strings to avoid type
conversions.

unclear or unsuitable licensing.
In general, we replace the files we can with liberally licensed data,
and remove all the others (in particular all the parts of the Canterbury
corpus that are not clearly in the public domain). The replacements
do not always have the exact same characteristics as the original ones,
but they are more than good enough to be useful for benchmarking.

Windows does not have struct iovec defined anywhere,
so we define our own version that's equal to what UNIX
typically has.
The bulk of this patch was contributed by Mohit Aron.

to 2 MB. This fixes issues with running the unit test on platforms with
little RAM (e.g. some ARM boards).
Also, reactivate the 2 MB test for 64-bit platforms; there's no good
reason why it shouldn't be.

warnings. There are still some in the unit test, but the main .cc file should
be clean. We haven't enabled -Wall for the default build, since the unit test
is still not clean.
This also fixes a real bug in the open-source implementation of
ReadFileToStringOrDie(); it would not detect errors correctly.
I had to go through some pains to avoid performance loss as the types
were changed; I think there might still be some with 32-bit if and only if LFS
is enabled (ie., size_t is 64-bit), but for regular 32-bit and 64-bit I can't
see any losses, and I've diffed the generated GCC assembler between the old and
new code without seeing any significant choices. If anything, it's ever so
slightly faster.
This may or may not enable compression of very large blocks (>2^32 bytes)
when size_t is 64-bit, but I haven't checked, and it is still not a supported
case.

Measure() loop. This gives all algorithms a small speed boost, except Snappy which
already didn't do reallocation (so the measurements were slightly biased in its
favor).

the differences from the opensource code. Will make it easier
in the future to mix-and-match third-party code that uses
snappy with google code.
Currently, csearch shows that the only external user of
"namespace zippy" is some bigtable code that accesses
a TEST variable, which is temporarily kept in the zippy
namespace.

Replace the Apache 2.0 license header by the BSD-type license header;
somehow a lot of the files were missed in the last round.

Unbreak the build; the relicensing removed a bit too much (only comments
were intended, but I also accidentially removed some of the top lines of
the actual source).

among others, Windows support. For Windows in specific, we could have used
CreateFileMapping/MapViewOfFile, but this should at least get us a bit closer
to compiling, and is of course also relevant for embedded systems with no MMU.
