Fully support OpenBSD 7.3
This change (1) upgrades to OpenBSD's newer kernel ABIs, and (2)
modifies APE to have a read-only data segment. Doing this required
creating APE Loader v1.1, which is backwards and forwards compatible
with the previous version.

If you've run the following commands in the past to install your APE
Loader systemwide, then you need to run them again. Ad-hoc installations
shouldn't be impacted. It's also recommended that APE binaries be remade
after upgrading, since they embed old versions of the APE Loader.

    ape/apeuninstall.sh
    ape/apeinstall.sh

This change does more than just fix OpenBSD. The new loader is smarter
and more reliable. We're now able create much tinier ELF and Mach-O data
structures than we could before. Both APE Loader and execvpe() will now
normalize ambiguous argv[0] resolution the same way as the UNIX shell.
Badness with TLS linkage has been solved.

Fixes #826

e75ffde09e Get codebase completely working with LLVM
You can now build Cosmopolitan with Clang:

    make -j8 MODE=llvm
    o/llvm/examples/hello.com

The assembler and linker code is now friendly to LLVM too.
So it's not needed to configure Clang to use binutils under
the hood. If you love LLVM then you can now use pure LLVM.
