The cosmopolitan command interpreter now has 13 builtin commands, variable support, support for ; / && / || syntax, asynchronous support, and plenty of unit tests with bug fixes. This change fixes a bug in posix_spawn() with null envp arg. strace logging now uses atomic writes for scatter functions. Breaking change renaming GetCpuCount() to _getcpucount(). TurfWar is now updated to use the new token bucket algorithm. WIN32 affinity masks now inherit across fork() and execve().
