Justine Tunney 117d0111ab Fix space path bug in (#11)
In addition to removing the URI downloading support. It was originally
intended to have this command play YouTube videos too but that support
was never completed. Latest release binaries can be obtained via:

    wget      # 284k ape executable

Justine Tunney 8da931a7f6 Add chibicc
This program popped up on Hacker News recently. It's the only modern
compiler I've ever seen that doesn't have dependencies and is easily
modified. So I added all of the missing GNU extensions I like to use
which means it might be possible soon to build on non-Linux and have
third party not vendor gcc binaries.

Justine Tunney ea0b5d9d1c 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:

Justine Tunney db33973e0a Get fork() working on Windows
This is done without using Microsoft's internal APIs. MAP_PRIVATE
mappings are copied to the subprocess via a pipe, since Microsoft
doesn't want us to have proper COW pages. MAP_SHARED mappings are
remapped without needing to do any copying. Global variables need
copying along with the stack and the whole heap of anonymous mem.
This actually improves the reliability of the redbean http server
although one shouldn't expect 10k+ connections on a home computer
that isn't running software built to serve like Linux or FreeBSD.

blinkenlights now does a pretty good job emulating what happens when
binaries boot from BIOS into long mode. So it's been much easier to
debug the bare metal process and wrinkle out many issues.

Justine Tunney 9e3e985ae5 Make terminal ui binaries work well everywhere
Here's some screenshots of an emulator tui program that was compiled on
Linux, then scp'd it to Windows, Mac, and FreeBSD.

How is this even possible that we have a nontrivial ui binary that just
works on Mac, Windows, Linux, and BSD? Surely a first ever achievement.

Fixed many bugs. Bootstrapped John McCarthy's metacircular evaluator on
bare metal in half the size of Altair BASIC (about 2.5kb) and ran it in
emulator for fun and profit.

Justine Tunney 23d333c090 Make more improvements
This change includes many bug fixes, for the NT polyfills, strings,
memory, boot, and math libraries which were discovered by adding more
tools for recreational programming, such as PC emulation. Lemon has also
been vendored because it works so well at parsing languages.

Justine Tunney 416fd86676 Make improvements
- Emulator can now test the αcτµαlly pδrταblε εxεcµταblε bootloader

- Whipped up a webserver named redbean. It services 150k requests per
  second on a single core. Bundling assets inside zip enables extremely
  fast serving for two reasons. The first is that zip central directory
  lookups go faster than stat() system calls. The second is that both
  zip and gzip content-encoding use DEFLATE, therefore, compressed
  responses can be served via the sendfile() system call which does an
  in-kernel copy directly from the zip executable structure. Also note
  that red bean zip executables can be deployed easily to all platforms,
  since these native executables work on Linux, Mac, BSD, and Windows.

- Address sanitizer now works very well

Justine Tunney f213556366 Add binfmt_misc workaround detector to builds
This is a recently introduced Linux Kernel feature that gives people
like Debian package mantainers the power to arbitrarily redefine how
executables are interpreted by the kernel. If your system gets tuned
this way and you're not able to disable it, then you need to restore
default behavior for the APE MZqFpD prefix as follows:

    sudo sh -c "echo ':APE:M::MZqFpD::/bin/sh:' >/proc/sys/fs/binfmt_misc/register"

This prefix will cover all .com executables built with this tooling.
Please don't run the above command unless you're certain you need it.
See #2 for additional context.

Justine Tunney f4f4caab0e Add x86_64-linux-gnu emulator
I wanted a tiny scriptable meltdown proof way to run userspace programs
and visualize how program execution impacts memory. It helps to explain
how things like Actually Portable Executable works. It can show you how
the GCC generated code is going about manipulating matrices and more. I
didn't feel fully comfortable with Qemu and Bochs because I'm not smart
enough to understand them. I wanted something like gVisor but with much
stronger levels of assurances. I wanted a single binary that'll run, on
all major operating systems with an embedded GPL barrier ZIP filesystem
that is tiny enough to transpile to JavaScript and run in browsers too.

Justine Tunney 467504308a Improve emulator color math
Video game emulators seem to convert colors for modern displays poorly.
Check out where we notice in the CRT
displays Super Mario Bros with a blue sky, whereas the PC shows purple.

It's likely b/c NTSC used Illuminant C whereas sRGB uses Illuminant D65.
See the improvement:
Now you can play video games in the terminal as they looked in the 80's.

This change also reduces CPU usage to a third.

Justine Tunney 4918121810 Add new calculator app
Cosmopolitan makes it easy to build and maintain programming languages,
since it abstracts system call #ifdef toil, so you can focus on vision.
Here's an example of a language that isn't turing complete, weighing in
at <1,000 lines of modern C, intended to help with testing libc / libm:

    .1 .2 + .3 - abs epsilon < assert
    pi sqrt pi sqrt * pi - abs epsilon < assert
    -.5 rint dup 0 = assert signbit assert
    -.5 nearbyint dup 0 = assert signbit assert
    -.5 ceil dup 0 = assert signbit assert
    -.5 trunc dup 0 = assert signbit assert
    -.5 round -1 = assert
    -.5 floor -1 = assert
    0 signbit ! assert

CALCULATOR.COM pays homage to CALC.EXE recently removed from Windows 10.
Microsoft should bundle this app instead. It too is roughly 100kb, works
just fine w/ command prompt, and portable since it runs on Mac/Linux/BSD
too while bundling even more features than the calculator on

It should be possible to run CALCULATOR.COM on Android and iOS too, just
in case anyone needs a backend pipe driven framework, for graphical user
interfaces of calculators. Sadly we haven't tried it since we don't know
how to run software on telephones so the system call support is a priori
