[PATCH 0/2] nolibc: Add sendfile()

[Daniel Palmer]

This is another thing from my backlog[0] and seemed simple enough so
sending now. Also, this feels right for nolibc as it lets you move lots
of data around without needing to allocate memory or even transfer it
into userspace. I've used it to implement cp and dd in my 64KB userspace
for linux on the sega megadrive.

There is some 32bit weirdness again, I think I caught that and added
some static asserts to make sure it doesn't silently break.

Maybe the test should actually test the offset?

0 - fallocate(), static pie, sockets,...
