Use shuffle+add instead of vector subscripting in SSE2 Adler-32
...
Shuffle+add is more efficient and also works on gcc versions that don't
support subscripting of vector types (pre-4.6).

Update licensing status
...
I've decided to simplify and standardize the licensing status for the
library by using the MIT license instead of CC0 (a.k.a. "public
domain"). This eliminates the somewhat controversial 4(a) clause in
CC0, and, for this and other reasons, should (somewhat ironically) make
it easier for some people to use and contribute to the project.
Note: copyright will apply to new changes and to new versions of the
work as a whole. Of course, versions previously released as public
domain remain public domain where legally recognized.

Avoid "exporting" symbols from static library
...
It was reported that API symbols were being "exported" from the static
library built with MSVC, causing them to remain exported after being
linked into another program. It turns out this was actually a problem
outside of MSVC as well. The solution is to always build the static and
shared libraries from different object files, where the API symbols are
exported from the shared library object files but not from the static
library object files.
