[PATCH v2 00/16] crypto/cipher: Class hierarchy cleanups

[Richard Henderson]

Mostly this is intended to cleanup the class hierarchy
used for the ciphers.  We currently have multiple levels
of dispatch, and multiple separate allocations.  The final
patches rearrange this to one level of indirect call, and
all memory allocated contiguously.

But on the way there are a number of other misc cleanups.

Changes in v2:
  * Dropped move of QCryptoCipher typedef.
  * Moved QCryptoCipherDriver typedef to include/crypto/cipher.h.
  * Renamed included files to *.c.inc.
  * Fixed errors with old versions of nettle and gcrypt.

Based-on: <20200828132716.279782-1-berrange@redhat.com>
("crypto: fix build with gcrypt")

which does at least allow *-softmmu builds to complete,
though I still have issues with *-linux-user.
