only need one element.

properly cases where gettimeofday() can stand return the same
result twice (as sometimes on GNU/Hurd) or go backwards
(as when the user adjusts the clock). We avoid a division-by-zero,
and put a lower bound on the number of iterations -- the same
amount as we use to calibrate.
We should probably use CLOCK_MONOTONIC for platforms that support
it, to be robust against clock adjustments; we already use Windows'
monotonic timers. However, that's for a later changelist.

as MSVC doesn't include it. Replace with QueryPerformanceCounter(),
which is monotonic and probably reasonably high-resolution.
(Some machines have traditionally had bugs in QPC, but they should
be relatively rare these days, and there's really no much better
alternative that I know of.)

I thought I'd already committed this patch, so that the 1.0.1 release already
would have a Windows-compatible snappy_unittest, but I'd seemingly deleted it
instead, so this is a reconstruction.

I've made a few changes since Martin's version; mostly style nits, but also
a semantic change -- most functions that return bool in the C++ version now
return an enum, to better match typical C (and zlib) semantics.
I've kept the copyright notice, since Martin is obviously the author here;
he has signed the contributor license agreement, though, so this should not
hinder Google's use in the future.
We'll need to update the libtool version number to match the added interface,
but as of http://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html
I'm going to wait until public release.

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.

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).

We can't get this 100% hermetic anyhow, due to files like lt~obsolete.m4,
