b75a1171d8 Give sendfile(2) a SF_SYNC flag which makes it wait until all mbufs 
referencing the files VM pages are returned from the network stack,
making changes to the file safe.

This flag does not guarantee that the data has been transmitted to the
other end.

df19774d2f Note that, thanks to the work by Alan Cox et al, some arch'es 
don't need sendfile() buffers any more.

017aaf79e1 Since sendfile(2) works on regular files only, 
which have no negative offsets, "negative" and
"invalid" are equivalent WRT the offset argument.

186e347f2c Fixed a bug in sendfile(2) where the sent data would be corrupted due 
to sendfile(2) being erroneously automatically restarted after a signal
is delivered. Fixed by converting ERESTART to EINTR prior to exiting.

Updated manual page to indicate the potential EINTR error, its cause
and consequences.

Stop calling system calls "function calls".

Use "The .Fn system call" a-la "The .Nm utility".

When referring to a non-BSD implementation in
the HISTORY section, call syscall a function,
to be safe.
