- Add documentation to for sys_unveil.
- Inline the chomp function in the unveil tool.

e81edf7b04 Improve pledge() and unveil()
The pledge.com command now supports the new [WIP] unveil() support. For
example, to strongly sandbox our command for listing directories.

    o//tool/build/assimilate.com o//examples/ls.com
    pledge.com -v /etc -p 'stdio rpath' o//examples/ls.com /etc

This file system sandboxing is going to be perfect for us, because APE
binaries are self-contained static executables that really don't use the
filesystem that much. On the other hand, with non-static executables,
sandboxing is going to be more difficult. For example, here's how to
sandbox the `ls` command on the latest Alpine:

    pledge.com -v rx:/lib -v /usr/lib -v /etc -p 'stdio rpath exec' ls /etc

This change fixes the `execpromises` API with pledge().

This change also adds unix.unveil() to redbean.

Fixes #494

5f4f6b0e69 Make _Thread_local work across platforms
We now rewrite the binary image at runtime on Windows and XNU to change
mov %fs:0,%reg instructions to use %gs instead. There's also simpler
threading API introduced by this change and it's called _spawn() and
_join(), which has replaced most clone() usage.

Make build process quota overridable (#430)
P had the same assignment as F. This is now fixed so that it is
possible to increase RLIMIT_NPROC (e.g. when trying to build
on system accounts with more than 1024 processes running).

e96aceae41 Bump support up to FreeBSD 13 and NetBSD 9.2
These releases are really exciting since they contained the patches we
worked to get upstreamed. It means that their /bin/sh interpreters all
work fine with Actually Portable Executable now.

If you use WSL then you may want to delete /tmp/ape, o/tmp/ape, and
/usr/bin/ape before running make again. That should resolve issues.

13ee75150c Improve redbean plus code size optimizations
This change turns symbol table compression back on using Puff, which
noticeably reduces the size of programs like redbean and Python. The
redbean web server receives some minor API additions for controlling
things like SSL in addition to filling gaps in the documentation.

425ff5dff0 Refactor some code
- Write tests for cthreads
- Fix bugs in pe2.com tool

- Consolidate the cthread header files
- Some code size optimizations for MODE=
- Attempted to squash a tls linker warning
- Attempted to get futexes working on FreeBSD

de5de19004 Make improvements
- Document redbean's argon2 module
- Fix regressions in cthreads library
- Make testlib work better with threads
- Give the cthreads library lots of love
- Remove some of the stdio assembly code
- Implement getloadavg() across platforms
- Code size optimizations for errnos, etc.
- Only check for signals in main thread on Windows
- Make errnos for dup2 / dup3 consistent with posix

This change also fixes a bug in the argon2 module, where the NUL
terminator was being included in the hash encoded ascii string. This
shouldn't require any database migrations to folks who found this module
and productionized it, since the argon2 library treats it as a c string.

4e9662cbc7 Write tests for new APE loader and fix bugs
- Add FreeBSD-specific mmap() flags
- Reduce size of the APE loader from 8kb to 4kb
- Work towards fixing the Makefile build on WSL
- Automate testing of APE no-modify-self behaviors
- Make the ape.S shell script code cleaner and tinier
- Improve the APE sanity check to test behavior better
- Fixed issue with ShowCrashReports() sigaltstack() on BSDs
- Delete symbols for S_MODE magnums which wasted compile time

If you checked out yesterday's APE commit, please run:

    rm -f /usr/bin/ape o/tmp/ape /tmp/ape "${TMPDIR:-/tmp}/ape"

Because this change fixes certain aspects of the new ABI. We don't have
automated migrations for APE loader versions yet. Thanks! You can also
download prebuilt binaries here:

- https://justine.lol/ape.elf    (Linux/FreeBSD/NetBSD/OpenBSD)
- https://justine.lol/ape.macho  (Apple)

Install the appropriate one as `/usr/bin/ape`.
