Introduce native support for MacOS ARM64 There's a new program named ape/ape-m1.c which will be used to build an embeddable binary that can load ape and elf executables. The support is mostly working so far, but still chasing down ABI issues.

Restart CI for New Technology and UBSAN hunting Continuous Integration (via runit and runitd) is now re-enabled on win7 and win10. The `make test` command, which runs the tests on all systems is now the fastest and most stable it's been since the project started. UBSAN is now enabled in MODE=dbg in addition to ASAN. Many instances of undefined behavior have been removed. Mostly things like passing a NULL argument to memcpy(), which works fine with Cosmopolitan Libc, but that doesn't prevents the compiler from being unhappy. There was an issue w/ GNU make where static analysis claims a sprintf() call can overflow. We also now have nicer looking crash reports on Windows since uname should now be supported and msys64 addr2line works reliably.

COSMOPOLITAN_C_START_
Get Cosmopolitan into releasable state A new rollup tool now exists for flattening out the headers in a way that works better for our purposes than cpp. A lot of the API clutter has been removed. APIs that aren't a sure thing in terms of general recommendation are now marked internal. There's now a smoke test for the amalgamation archive and gigantic header file. So we can now guarantee you can use this project on the easiest difficulty setting without the gigantic repository. A website is being created, which is currently a work in progress: https://justine.storage.googleapis.com/cosmopolitan/index.html
