ff28e38ef1 Close more superfluous file descriptors
GitHub Actions leaks file descriptors with numbers greater than a
hundred. But our test runner only checked for FDs up to 64.

d5312b60f7 Make improvements to locking
This change makes pthread_mutex_lock() as fast as _spinlock() by
default. Thread instability issues on NetBSD have been resolved.
Improvements made to gdtoa thread code. Crash reporting will now
synchronize between threads in a slightly better way.

- Remove double slashes in NT paths automatically (#428)
- Make strerror() smarter about showing NT errors (#428)

Fixes #428

a0ddb889da Polyfill sched_yield() on XNU
We were using the Mach system call swtch() earlier. It's possible Apple
removed this system call in their recent 12.4 upgrade. We're better off
using x86 PAUSE here, since Mach is less public than the UNIX syscalls.

See #426

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
file descriptors in general. We now document fixed addresses that are
needed for low level allocations.

1c387727fe Add long double printf formatting support
You can now easily print numbers that have 80 bits of precision. This
change also imports many of the test vectors from the gdtoa codebase.

8b72490431 Make mutex calling code 10x tinier
Calls to lock/unlock functions are now NOPs by default. The first time
clone() is called, they get turned into CALL instructions. Doing this
caused funcctions like fputc() to shrink from 85 bytes to 45+4 bytes.
Since the ANSI solution of `(__threaded && lock())` inlines os much
superfluous binary content into functions all over the place.

8cdec62f5b Apply even more fixups
- Finish cleaning up the stdio unlocked APIs
- Make __cxa_finalize() properly thread safe
- Don't log locks if threads aren't being used
- Add some more mutex guards to places using _mmi
- Specific lock names now appear in the --ftrace logs
- Fix mkdeps.com generating invalid Makefiles sometimes
- Simplify and fix bugs in the test runner infrastructure
- Fix issue where sometimes some functions wouldn't be logged

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.

c260345e06 Make locks more reliable
This change switches most of the core locks to be re-entrant, in order
to reduce the chance of deadlocking code that does, clever things with
asynchronous signal handlers. This change implements it it in pthreads
so we're one step closer to having a standardized threading primitives

701564de19 Perform better fixups of NT paths in execve()
This change ensures we do a better job translating /c/foo.bar paths into
c:/foo.bar paths on Windows when generating the CreateProcess() cmd line
thus fixing a regression that happened in the last two months when using
the help() feature of Actually Portable Python in the CMD.EXE shell.

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.

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.
