	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

	(_nettle_armors): Add leading underscore on these data symbols.
	Update all internal use. Macros without leading underscore remain,

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
	software implementation, while the EVP functions enables
	platform-specific code, e.g., using the x86 AES-NI instructions.
	(nettle_openssl_init): New function.

	* testsuite/pss-test.c: Delete magic to let valgrind to check if

	* arm: Add .arch directives for armv6. This allows building these

	* fat-setup.h (DEFINE_FAT_FUNC): Check value of function pointer,
	before calling fat_init. Should be correct even without memory
	barrier.

	The checks of the relevant pointer in DEFINE_FAT_FUNC is more
	robust.
