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.

Mint APE Loader v1.5 This change ports APE Loader to Linux AARCH64, so that Raspberry Pi users can run programs like redbean, without the executable needing to modify itself. Progress has also slipped into this change on the issue of making progress better conforming to user expectations and industry standards regarding which symbols we're allowed to declare

Improve system call wrappers This change improves copy_file_range(), sendfile(), splice(), openpty(), closefrom(), close_range(), fadvise() and posix_fadvise() in addition to writing tests that confirm things like errno and seeking behavior across platforms. We now less aggressively polyfill behavior with some of these functions when the platform support isn't available. Please see: https://justine.lol/cosmopolitan/functions.html

Support non-blocking i/o across platforms This change introduces new tests for `O_NONBLOCK` and `SOCK_NONBLOCK` to confirm that non-blocking i/o is now working on all supported platforms, including Windows. For example, you can now say on Windows, MacOS, etc.: socket(AF_INET, SOCK_STREAM | SOCK_NONBLOCK, IPPROTO_TCP); To create a non-blocking IPv4 TCP socket. Or you can enable non-blocking i/o on an existing socket / pipe / etc. file descriptor by calling fcntl fcntl(fd, F_SETFL, fcntl(fd, F_GETFL) | O_NONBLOCK); This functionality is polyfilled on older Linux kernels too, e.g. RHEL5. Now that fcntl() support is much better the FIOCLEX / FIONCLEX polyfills for ioctl() have been removed since they're ugly non-POSIX diameond APIs This change fixes a weakness in kprintf() that was causing Windows trace tools to frequently crash.
