  Revert "crypto: testmgr - Add multibuffer hash testing"

This reverts commit 8b54e6a8f4156ed43627f40300b0711dc977fbc1.

The multibuffer tests has a number of bugs.  For example, the SG
lists for the filler requests weren't initialised properly, and
it fails to take data-keyed algorithms such as poly1305 into account.

More importantly, the chaining interface itself is under review.
Revert this until the interface is fully settled.

Add rudimentary multibuffer acomp testing.  Testing coverage is
extended to compression vectors only.  However, as the compression
vectors are compressed and then decompressed, this covers both
compression and decompression.

This is based on a patch by Eric Biggers <ebiggers@google.com>.

Add limited self-test for multibuffer hash code path.  This tests
only a single request in chain of a random length.  The other
requests are either all of the same length as the one being tested,
or random lengths between 0 and PAGE_SIZE * 2 * XBUFSIZE.

Potential extension include testing all requests rather than just
the single one.

The 'comp' compression API has been superseded by the acomp API, which
is a bit more cumbersome to use, but ultimately more flexible when it
comes to hardware implementations.

Now that all the users and implementations have been removed, let's
remove the core plumbing of the 'comp' API as well.

The 'comp' API is obsolete and will be removed, so remove this comp
implementation.

In preparation for the partial removal of NULL dst acomp support,
remove the tests for them.

Add Kerberos crypto tests to the test manager database.  This covers:

	camellia128-cts-cmac		samples from RFC6803
	camellia256-cts-cmac		samples from RFC6803
	aes128-cts-hmac-sha256-128	samples from RFC8009
	aes256-cts-hmac-sha384-192	samples from RFC8009

but not:

	aes128-cts-hmac-sha1-96
	aes256-cts-hmac-sha1-96

as the test samples in RFC3962 don't seem to be suitable.
