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.
