Make improvements
- Fix build flakes - Polyfill SIGWINCH on Windows - Fix an execve issue on Windows - Make strerror show more information - Improve cmd.exe setup/teardown on Windows - Support bracketed paste mode in Blinkenlights - Show keyboard shortcuts in Blinkenlights status bar - Fixed copy_file_range() and copyfile() w/ zip filesystem - Size optimize GetDosArgv() to keep life.com 12kb in size - Improve Blinkenlights ability to load weird ELF executables - Fix program_executable_name and add GetInterpreterExecutableName - Make Python in tiny mode fail better if docstrings are requested - Update Python test exclusions in tiny* modes such as tinylinux - Add bulletproof unbreakable kprintf() troubleshooting function - Remove "oldskool" keyword from ape.S for virus scanners - Fix issue that caused backtraces to not print sometimes - Improve Blinkenlights serial uart character i/o - Make clock_gettime() not clobber errno on xnu - Improve sha256 cpuid check for old computers - Integrate some bestline linenoise fixes - Show runit process names better in htop - Remove SIGPIPE from ShowCrashReports() - Make realpath() not clobber errno - Avoid attaching GDB on non-Linux - Improve img.com example
