Release Cosmopolitan v3.3.2

- Write some more unit tests
- memcpy() on ARM is now faster
- Address the Musl complex math FIXME comments
- Some libm funcs like pow() now support setting errno
- Import the latest and greatest math functions from ARM
- Use more accurate atan2f() and log1pf() implementations
- atoi() and atol() will no longer saturate or clobber errno

+## Copyright Policy Exceptions
+
+### Tests
+
+You're encoraged to claim ownership of your test code. If you add a new
+file under the `test/` directory, then you should put your name in the
+ISC license header at the top of the file. If you add new test cases to
+an existing unit test file, then you're encouraged to append a line with
+your name to the existing copyright header of that file.
+
+### Exceptional Features
+
+Let's say you discovered a faster better way to implement `log10()` and
+you want to give it to Cosmopolitan. In cases like this, it really isn't
+appropriate for Justine to own your code. What you could do instead, is
+write your own new and improved `log10.c` from scratch, put your name on
+the top with the ISC license, and then add a `__notice()` directive so
+that your name will be embedded inside every executable that links the
+`log10()` function. This will help you get your name out there. Please
+note you need get approval from Justine each time you want to do this.

 ## Style Guide
 
 You can use clang-format to automatically format your files:

-### Source Files
-
-- Must use include paths relative to the root of the repository
-- Must have comment at top of file documenting copyright and license
-- Must have notice embedding if not owned by Justine (exception: tests)
-- May use language extensions that are supported by both GCC and Clang
-- Should use Google indentation (otherwise use `/* clang-format off */`)
-- Should use asm() instead of compiler APIs (exception: ctz, clz, memcpy)
-
-### Header Files
-
-- Must not have copyright or license comments
-- Must have once guards (otherwise change `.h` to `.inc`)
-- Must be ANSI C89 compatible to be included in the amalgamation header
-- Must include its dependencies (exception: libc/integral/normalize.inc)
-- Must not define objects (i.e. `cc -c -xc foo.h` will produce empty `.o`)
-- Should not use typedefs
-- Should not use forward declarations
-- Should not include documentation comments
-- Should not include parameter names in prototypes
-- Should not pose problems if included by C++ or Assembly sources
-- Should not declare non-ANSI code, at all, when the user requests ANSI

-### Build Config
-
-- Must not write files outside `o/`
-- Must not communicate with Internet
-- Must not depend on system libraries
-- Must not depend on system commands (exception: sh, make, gzip, zip)
