Make improvements
- Invent openatemp() API - Invent O_UNLINK open flag - Introduce getenv_secure() API - Remove `git pull` from cosmocc - Fix utimes() when path is NULL - Fix mktemp() to never return NULL - Fix utimensat() UTIME_OMIT on XNU - Improve utimensat() code for RHEL5 - Turn `argv[0]` C:/ to /C/ on Windows - Introduce tmpnam() and tmpnam_r() APIs - Fix more const issues with internal APIs - Permit utimes() on WIN32 in O_RDONLY mode - Fix fdopendir() to check fd is a directory - Fix recent crash regression in landlock make - Fix futimens(AT_FDCWD, NULL) to return EBADF - Use workaround so `make -j` doesn't fork bomb - Rename dontdiscard to __wur (just like glibc) - Fix st_size for WIN32 symlinks containing UTF-8 - Introduce stdio ext APIs needed by GNU coreutils - Fix lstat() on WIN32 for symlinks to directories - Move some constants from normalize.inc to limits.h - Fix segv with memchr() and memcmp() overlapping page - Implement POSIX fflush() behavior for reader streams - Implement AT_SYMLINK_NOFOLLOW for utimensat() on WIN32 - Don't change read-only status of existing files on WIN32 - Correctly handle `0x[^[:xdigit:]]` case in strtol() functions
