redbean improvements: - Explicitly disable corking - Simulate Python regex API for Lua - Send warmup requests in main process on startup - Add Class-A granular IPv4 network classification - Add /statusz page so you can monitor your redbean's health - Fix regressions on OpenBSD/NetBSD caused by recent changes - Plug Authorization header into Lua GetUser and GetPass APIs - Recognize X-Forwarded-{For,Host} from local reverse proxies - Add many additional functions to redbean Lua server page API - Report resource usage of child processes on `/` listing page - Introduce `-a` flag for logging child process resource usage - Introduce `-t MILLIS` flag and `ProgramTimeout(ms)` init API - Introduce `-H "Header: value"` flag and `ProgramHeader(k,v)` API Cosmopolitan Libc improvements: - Make strerror() simpler - Make inet_pton() not depend on sscanf() - Fix OpenExecutable() which broke .data section earlier - Fix stdio in cases where it overflows kernel tty buffer - Fix bugs in crash reporting w/o .com.dbg binary present - Add polyfills for SO_LINGER, SO_RCVTIMEO, and SO_SNDTIMEO - Polyfill TCP_CORK on BSD and XNU using TCP_NOPUSH magnums New netcat clone in examples/nc.c: While testing some of the failure conditions for redbean, I noticed that BusyBox's `nc` command is pretty busted, if you use it as an interactive tool, rather than having it be part of a pipeline. Unfortunately this'll only work on UNIX since Windows doesn't let us poll on stdio and sockets at the same time because I don't think they want tools like this running on their platform. So if you want forbidden fruit, it's here so enjoy it
