[PATCH 0 of 4] sendfile(SF_NODISKIO) on FreeBSD

[Maxim Dounin]

Hello!

Here are some experimental patches which remove AIO preloading
previously used with sendfile(SF_NODISKIO) on FreeBSD, so the code
instead relies on non-blocking loading data from disk by sendfile()
itself, as available since FreeBSD 11 (that is, on all supported
FreeBSD versions).

Review and comments appreciated.
