Add cpu / mem / fsz limits to build system Thanks to all the refactorings we now have the ability to enforce reasonable limitations on the amount of resources any individual compile or test can consume. Those limits are currently: - `-C 8` seconds of 3.1ghz CPU time - `-M 256mebibytes` of virtual memory - `-F 100megabyte` limit on file size Only one file currently needs to exceed these limits: o/$(MODE)/third_party/python/Objects/unicodeobject.o: \ QUOTA += -C16 # overrides cpu limit to 16 seconds This change introduces a new sizetol() function to LIBC_FMT for parsing byte or bit size strings with Si unit suffixes. Functions like atoi() have been rewritten too.

Greatly expand system() shell code features 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().

Fix warnings This change fixes Cosmopolitan so it has fewer opinions about compiler warnings. The whole repository had to be cleaned up to be buildable in -Werror -Wall mode. This lets us benefit from things like strict const checking. Some actual bugs might have been caught too.
