	From Nikos Mavrogiannopoulos.
	* sha1-compress.c (nettle_sha1_compress): Renamed, and promoted to
	public function, since there's known appliation usage (filezilla).
	* sha1.h (_nettle_sha1_compress): Old name, now a preprocessor
	alias for the new name.
	* md5-compress.c (nettle_md5_compress): Similarly renamed (used by
	sogo).
	* md5.h (_nettle_md5_compress): Old name,, now a preprocessor
	alias for the new name.

	files, which are not installed..
	* Makefile.in (DISTFILES): Added above files.

	* libnettle.map.in: Use a different symbol version for _nettle_*
	symbols, depending on the minor release. This marks these symbols
	explicitly not part of the public Nettle ABI.

	Discourage direct access to data symbols with non-public size.
	Direct references to these symbols may result in copy-relocations
	like R_X86_64_COPY, which make the symbol size leak into the ABI.
	* ecc-curve.h (_nettle_secp_192r1, _nettle_secp_224r1)
	(_nettle_secp_256r1, _nettle_secp_384r1, _nettle_secp_521r1): Add
	leading underscore on these data symbols.

	* nettle-meta.h (_nettle_ciphers, _nettle_hashes, _nettle_aeads)
	(_nettle_armors): Add leading underscore on these data symbols.
	Update all internal use. Macros without leading underscore remain,
	and expand to access via accessor functions nettle_get_ciphers and
	similar.

2017-08-03  Daniel P. Berrange  <berrange@redhat.com>

	* examples/nettle-openssl.c: Rewritten to use openssl's EVP APIs.
	The older cipher-specific functions always use openssl's generic
