Move zipos into runtime package
This way complex runtime features (e.g. ftrace, symbol tables) can
always yoink zipos support. This is important now that apelink.com
automates embedding symbol tables for multiple cpus.

Introduce new fatcosmocc command
This new script is an alternative to the `cosmocc` command. It's still a
work in progress. It abstracts all the gory details of building separate
copies of your executable and then running the apelink.com program.

Make stderr go faster
This change makes _IONBF (unbuffered) stdio handles go 20x faster for
certain kinds of formatting directives by being smarter about buffers

Introduce post-linker that converts ELF to PE
If you build a static ELF executable in `ld -q` mode (which leaves rela
sections inside the binary) then you can run it through the elf2pe.com
program afterwards, which will turn it into a PE executable. We have a
new trick for defining WIN32 DLL imports in C without any assembly code.
This also achieves the optimally tiny and perfect PE binary structure.

We need this because it isn't possible to have a GNU ld linker script
generate a PE file where the virtual pointer and the file pointer can
drift apart. This post-linker can do that. One cool benefit is we can
now use a smaller 512-byte alignment in the file, and an even bigger
64kb alignment for the segment virtual addresses, and the executable
ends up being smaller.

Another program introduced by this change is pecheck.com which can do
extensive linting of PE static executables to help explain why Windows
won't load it.

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.

Make considerably more progress on AARCH64
- Utilities like pledge.com now build
- kprintf() will no longer balk at 48-bit addresses
- There's a new aarch64-dbg build mode that should work
- gc() and defer() are mostly pacified; avoid using them on aarch64
- THIRD_PART_STB now has Arm Neon intrinsics for fast image handling

Get TEST_LIBC_STR passing on AARCH64
It's now possible to run commands like:

    make -j8 m=aarch64 o/aarch64/test/libc/str

Which will cross-compile and run the test suites in a qemu-aarch64
binary that's vendored in the third_party/qemu/ folder within your
x86_64 build environment.
