Fix warnings
This change fixes Cosmopolitan so it has fewer opinions about compiler
warnings. The whole repository had to be cleaned up to be buildable in
-Werror -Wall mode. This lets us benefit from things like strict const
checking. Some actual bugs might have been caught too.

Make ZipOS and Qemu work better
This change improves the dirstream library in a lot of respects,
especially for /zip/... files. Also turn off MAP_STACK on Aarch64
because Qemu seems to implement it differently than Linux and it's
probably responsible for a lot of mysterious crashes.

Replace COSMO define with _COSMO_SOURCE
This change might cause ABI breakages for /opt/cosmos. It's needed to
help us better conform to header declaration practices.

Mint APE Loader v1.5
This change ports APE Loader to Linux AARCH64, so that Raspberry Pi
users can run programs like redbean, without the executable needing
to modify itself. Progress has also slipped into this change on the
issue of making progress better conforming to user expectations and
industry standards regarding which symbols we're allowed to declare

Get us closer to building busybox
This change undefines __linux__ and adds APIs like clock_settime(). The
gosh darned getopt_long() API has been reintroduced, thanks to OpenBSD.

Introduce #include <cosmo.h> to toolchain users
This change improves the way internal APIs are being hidden behind the
`COSMO` define. The cosmo.h header will take care of defining that, so
that a separate define statement isn't needed. This change also does a
lot more to define which APIs are standard, and which belong to Cosmo.

Fix bugs in cosmocc toolchain
This change integrates e58abc1110b335a3341e8ad5821ad8e3880d9bb2 from
https://github.com/ahgamut/musl-cross-make/ which fixes the issues we
were having with our C language extension for symbolic constants. This
change also performs some code cleanup and bug fixes to getaddrinfo().
It's now possible to compile projects like ncurses, readline and python
without needing to patch anything upstream, except maybe a line or two.
Pretty soon it should be possible to build a Linux distro on Cosmo.

Validate privileged code relationships
- Work towards improving non-optimized build support
- Introduce MODE=zero which is -O0 without ASAN/UBSAN
- Use system GCC when ~/.cosmo.mk has USE_SYSTEM_TOOLCHAIN=1

Create ELF aliases for identical symbols
This change greatly reduces the number of modules that need to be
compiled. The only issue right now is that sometimes when viewing
symbol table entries, the aliased symbol is chosen.

Make improvements
This change progresses our AARCH64 support:

- The AARCH64 build and tests are now passing
- Add 128-bit floating-point support to printf()
- Fix clone() so it initializes cosmo's x28 TLS register
- Fix TLS memory layout issue with aarch64 _Alignas vars
- Revamp microbenchmarking tools so they work on aarch64
- Make some subtle improvements to aarch64 crash reporting
- Make kisdangerous() memory checks more accurate on aarch64
- Remove sys_open() since it's not available on Linux AARCH64

This change makes general improvements to Cosmo and Redbean:

- Introduce GetHostIsa() function in Redbean
- You can now feature check using pledge(0, 0)
- You can now feature check using unveil("",0)
- Refactor some more x86-specific asm comments
- Refactor and write docs for some libm functions
- Make the mmap() API behave more similar to Linux
- Fix WIFSIGNALED() which wrongly returned true for zero
- Rename some obscure cosmo keywords from noFOO to dontFOO

Be more lenient about stack memory
The new stack size is 256kb in order to compromise with llama.cpp's
aggressive use of stack memory, which can't be easily patched. This
change disables the dynamic alloca() and VLA warnings for now, plus
frame sizes for individual functions may be <=50% of the stack size

This only applies to code in the cosmo monorepo. Open source builds
should already be using an 8mb stack by default, like everyone else

Fix corner case in Linux stack mappings
We need to make sure no existing mappings exist between the
MAP_GROWSDOWN page and the guard page, since otherwise it's
not going to be able to grow down thus causing difficult to
troubleshoot failures.

Rewrite IPv4 Turf War backend

this running in production already!

Pay off more technical debt
This makes breaking changes to add underscores to many non-standard
function names provided by the c library. MODE=tiny is now tinier and
we now use smaller locks that are better for tiny apps in this mode.
Some headers have been renamed to be in the same folder as the build
package, so it'll be easier to know which build dependency is needed.
Certain old misguided interfaces have been removed. Intel intrinsics
headers are now listed in libc/isystem (but not in the amalgamation)
to help further improve open source compatibility. Header complexity
has also been reduced. Lastly, more shell scripts are now available.

Don't relocate file descriptor memory
This change fixes #496 where ASAN spotted a race condition that could
happen in multithreaded programs, with more than OPEN_MAX descriptors
when using ZipOS or Windows NT, which require tracking open file info
and this change fixes that table so it never relocates, thus allowing
us to continue to enjoy the benefits of avoiding locks while reading.

Improve open source compatibility
This change tunes the default stack size for the outside world to 8mb
while at the same time, reducing Cosmopolitan's default stack size to
64kb. You can override the stack size using STATIC_STACK_SIZE(). Your
build scripts should point to o//ape/public/ape.lds

This change also fixes the definition of SOMAXCONN and removes AF_RDS
since it's not polyfilled and Python 3.11 complained.
