Implemented algorithm array nettle_aeads.

ChangeLog

 2014-05-08  Niels Möller  <nisse@lysator.liu.se>
 
+	* Makefile.in (nettle_SOURCES): Added nettle-meta-aeads.c.
+	* nettle-meta.h (nettle_aeads): Declare array.
+	* nettle-meta-aeads.c (nettle_aeads): New file, new array.
+	* testsuite/meta-aead-test.c: New test case.
+	* testsuite/Makefile.in (TS_NETTLE_SOURCES): Added
+	meta-aead-test.c.
+
 	* aclocal.m4 (GMP_PROG_CC_FOR_BUILD): If CC_FOR_BUILD is gcc, add
 	-O option. This makes eccdata twice as fast.
