Introduce __MAP_NOFAULT, a mmap(2) flag that makes sure a mapping will not
cause a SIGSEGV or SIGBUS when a mapped file gets truncated. Access to
pages that are not backed by a file on such a mapping will be replaced by
zero-filled anonymous pages. Makes passing file descriptors of mapped files
usable without having to play tricks with signal handlers.
