Fix reporting of Lua stack items from various hook calls (#395)
Some hooks can be called after OnHttpRequest, which may leave an
anchored item on stack, so this have to be taken into account to
avoid spurious reports.

Redbean fix text detect (#388)
This resets istext between requests, which may cause response to be
zipped when not needed (on non-text content).

5a132f9652 Add seccomp bpf sandboxing to redbean
It's now possible to pass the `-S` or `-SS` flags to sandbox redbean
worker proecsses after they've been forked. The first `-S` flag is
intended to be a permissive builtin policy that limits system calls to
only that which the various parts of redbean serving need. The second
`-SS` flag is intended to be more restrictive, preventing things like
the Lua extensions you download off the web from using the HTTP client
or sockets APIs. In upcoming changes you'll be able to implement your
own Berkeley Packet Filter sandbox programs and load them via Lua.

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.

Fix memory deallocation while yielding in redbean. (#384)
The yielded coroutine was removed from the stack too early,
leaving it not being anchored, which led to memory freed prematurely.

281a0f2730 Implement raw system call for redbean lua code
You can now call functions like fork() from Lua and it'll work across
all supported platforms, including Windows. This gives you a level of
control of the system that Lua traditionally hasn't been able to have
due to its focus on old portable stdio rather modern POSIX APIs. Demo
code has been added to redbean-demo.com to show how it works.

This change also modifies Lua so that integer literals with a leading
zero will be interpreted as octal. That should help avoid shooting in
the foot with POSIX APIs that frequently use octal mode bits.

This change fixes a bug in opendir(".") on New Technology.

Lastly, redbean will now serve crash reports to private network IPs.
This is consistent with other frameworks. However that isn't served
to public IPs unless the -E flag is passed to redbean at startup.

Reset Lua stack to drop unused returned values (#382)

c13142dad2 Fix redbean certificate free error
This fixes a regression from a change a few weeks ago in git commit
af645fcbec which caused certificates to
not be free()'d correctly if the certificates are chained. dlmalloc()
should have printed an error in most build modes. ASAN caught it too.

23b72eb617 Add support for symbol table in .com files
This change fixes minor bugs and adds a feature, which lets us store the
ELF symbol table, inside the ZIP directory. We use the path /zip/.symtab
which can be safely removed using a zip editing tool, to make the binary
smaller after compilation. This supplements the existing method of using
a separate .com.dbg file, which is still supported. The intent is people
don't always know that it's a good idea to download the debug file. It's
not great having someone's first experience be a crash report, that only
has numbers rather than symbols. This will help fix that!

393ca4be40 Polyfill SIGCHLD on the New Technology
redbean will now cleanup child processes properly. New accounting
information is available too, such as page faults and memory usage. The
way it works is Cosmopolitan Libc samples the process collection on
entry into read() and poll() to see if SIGCHLD needs to be raised.

This change also fixes an issue with chibicc /tmp cleanup. There was
also a regression in MODE=dbg because STL needed ASAN runtime support.

868af3f950 Import C++ Standard Template Library
You can now use the hardest fastest and most dangerous language there is
with Cosmopolitan. So far about 75% of LLVM libcxx has been added. A few
breaking changes needed to be made to help this go smoothly.

- Rename nothrow to dontthrow
- Rename nodiscard to dontdiscard
- Add some libm functions, e.g. lgamma, nan, etc.
- Change intmax_t from int128 to int64 like everything else
- Introduce %jjd formatting directive for int128_t
- Introduce strtoi128(), strtou128(), etc.
- Rename bsrmax() to bsr128()

Some of the templates that should be working currently are std::vector,
std::string, std::map, std::set, std::deque, etc.

redbean: allow symlinks for -D path (#372)
Previously ProgramDirectory called isdirectory which returns false for
symlinks. instead just check directory with stat, and allow user to pass
`-D /tmp/foo/`, where /tmp/foo might be a symlink.

5e8ae2d5bc Restart CI for New Technology and UBSAN hunting
Continuous Integration (via runit and runitd) is now re-enabled on win7
and win10. The `make test` command, which runs the tests on all systems
is now the fastest and most stable it's been since the project started.

UBSAN is now enabled in MODE=dbg in addition to ASAN. Many instances of
undefined behavior have been removed. Mostly things like passing a NULL
argument to memcpy(), which works fine with Cosmopolitan Libc, but that
doesn't prevents the compiler from being unhappy. There was an issue w/
GNU make where static analysis claims a sprintf() call can overflow. We
also now have nicer looking crash reports on Windows since uname should
now be supported and msys64 addr2line works reliably.
