lib/reduce: Check if user's buffer crosses huge page boundary
If compress driver doesn't support SGL input of output
then we need to copy user's buffers into reduce internal
buffers

ut/reduce: use compress algorithm
The unit tests to this point used an algorithm that
just copied the data as-is with no compression.
Change it now to use the actual unit test compression
algorithm.

The unit tests to this point used an algorithm that

Change it now to use the actual unit test compression
algorithm.
A few unit tests need to be modified to account
for the compressible buffers - primarily those that
write a single 512 byte LBA in a 16KB chunk. These
will now be compressed down to a single I/O unit,
so some of the asserts need to be changed to adjust
for this.

ut/reduce: modify write_maps test to write full chunks
This test verifies that all of the io_unit_index[] entries
are written. For that to really happen, the write for
the chunks must not be compressible. Currently the compress
algorithm just copies the data and doesn't actually
compress - so writing a partial chunk works OK for this test.
But upcoming patches will add a 'real' compression unit test
algorithm - at which point, writing just part of a chunk
will be compressible since the non-written parts will be all
zero.
