It is possible for a buf to be reassigned between the dirty and clean
lists while gbincore_unlocked() looks in each list.  Avoid creating
a buffer in that case and fallback to a locked lookup.

This fixes a regression from r363482.

More discussion on potential improvements to the clean and dirty lists
handling is in the review.

This merges upstream patches from OpenSSL's master branch to add
KTLS infrastructure for TLS 1.0-1.3 including both RX and TX
offload and SSL_sendfile support on both Linux and FreeBSD.

Note that TLS 1.3 only supports TX offload.

A new WITH/WITHOUT_OPENSSL_KTLS determines if OpenSSL is built with
KTLS support.  It defaults to enabled on amd64 and disabled on all
other architectures.

`__vdev_disk_physio()` uses `abd_nr_pages_off()` to allocate a bio with
a sufficient number of iovec's to process this zio (i.e.
`nr_iovecs`/`bi_max_vecs`).  If there are not enough iovec's in the bio,
then additional bio's will be allocated.  However, this is a sub-optimal
code path.  In particular, it requires several abd calls (to
`abd_nr_pages_off()` and `abd_bio_map_off()`) which will have to walk
the constituents of the ABD (the pages or the gang children) because
they are looking for offsets > 0.

For gang ABD's, `abd_nr_pages_off()` returns the number of iovec's
needed for the first constituent, rather than the sum of all
constituents (within the requested range).  This always under-estimates
the required number of iovec's, which causes us to always need several
bio's.  The end result is that `__vdev_disk_physio()` is usually O(n^2)
for gang ABD's (and occasionally O(n^3), when more than 16 bio's are

This commit fixes `abd_nr_pages_off()`'s handling of gang ABD's, to
correctly determine how many iovec's are needed, by adding up the number
of iovec's for each of the gang children in the requested range.

This changes the behaviour to a 30s total timeout (needed when running
on slow emulated uniprocessor systems) and timing out after 10s without
any input. This also uses timespecsub() instead of ignoring the
nanoseconds field.

After this change the tests runs more reliably on QEMU and time out less

Moving the call to zfs_refcount_remove_many() in abd_free() to be called
before any of the ABD free variants are called. This is necessary
because abd_free_gang() adjusts the abd_size for the gang ABD. If the
parent's child references are removed after free'ing the gang ABD the
refcount is not adjusted correctly for the parent's children.

I also removed some stray abd_put() in comments and changed
abd_free_gang_abd() -> abd_free_gang().
