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.

Mint APE Loader v1.7
This change reduces the memory requirements of your APE Loader by 10x,
in terms of virtual memory size, thanks to the help of alloca(). We're
also now creating argument blocks with the same layout across systems.

Improve zip read-only filesystem
readdir() will now always yield an inode that's consistent with stat()
on ZipOS and Windows in general. More APIs have been updated to return
the appropriate error code when inappropriately trying to do ops, like
sockets, with a zip file descriptor. The path normalization algorithms
are now fully fleshed out. Some socket APIs have been fixed so they'll
raise EBADF vs. ENOTSOCK appropriately. Lastly seekdir() will now work
properly on NetBSD and FreeBSD (not sure why anyone would even use it)

Make stdin pollable on Windows
You can now play Super Mario Bros in CMD.EXE using Cosmopolitan! This is
thanks to a new worker thread that's spawned on Windows whenever any one
of poll(), select(), or ioctl(FIONREAD) is linked.

Improve wait statuses
This change has the insight that dwExitCode isn't an exit code but
rather should be used to pass the wait status. This lets us report
killing as a termination status, similar to UNIX. This change also
fixes the fact that exit(259) on Windows will break the parent due
way WIN32 is designed. We now work around that.

It turns out that NetBSD and OpenBSD, will let you have exit codes
beyond 255. This change will let you use them when it's possible.

Mint APE Loader v1.4
This change also incorporates more bug fixes and improvements to a wide
variety of small things. For example this fixes #860 so Windows console
doesn't get corrupted after exit. An system stack memory map issue with
aarch64 has been fixed. We no longer use O_NONBLOCK on AF_UNIX sockets.
Crash reports on Arm64 will now demangle C++ symbols, even when c++filt
isn't available. Most importantly the Apple M1 version of APE Loader is
brought up to date by this change. A prebuilt unsigned binary for it is
being included in build/bootstrap/. One more thing: retrieving the term
dimensions under --strace was causing the stack to become corrupted and
now that's been solved too. PSS: We're now including an ELF PT_NOTE for
APE in the binaries we build, that has the APE Loader version.

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.

e466dd0553 Add torture test for zipos file descriptors
This change hardens the code for opening /zip/ files using the system
call interface. Thread safety and signal safety has been improved for

needed for low level allocations.

dc0ea6640e Fix bugs with recent change
This change makes further effort towards improving our poll()
implementation on the New Technology. The stdin worker didn't work out
so well for Python so it's not being used for now. System call tracing
with the --strace flag should now be less noisy now on Windows unless
you modify the strace.internal.h defines to turn on some optional ones
that are most useful for debugging the system call wrappers.
