At least in neovim, `│vi:` is not recognized as a modeline because it
has no preceding whitespace. After fixing this, opening a file yields
an error because `net` is not an option. (`noet`, however, is.)
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.
This version has better error messages and safety checks. It supports
loading static position-independent executables. It correctly handles
more kinds of weird ELF program header layouts. A force flag has been
added to avoid system execve(). Finally the longstanding misalignment
with our ELF PT_NOTE section has been addressed.
