openssl: config engines in /etc/ssl/engines.cnf.d

This changes the configuration of engines from the global openssl.cnf to
files in the /etc/ssl/engines.cnf.d directory.  The engines.cnf file has
the list of enabled engines, while each engine has its own configuration
file installed under /etc/ssl/engines.cnf.d.

Patches were refreshed with --zero-commit.

+# list of supported algorithms, along with their driver, whether they
+# are hw accelerated or not, and the engine's configuration commands.

+
+# CIPHERS: either ALL, NONE, or a comma-separated list of ciphers to
+# enable [default=ALL]
+# It is recommended to disable the ECB ciphers; in most cases, it will
+# only be used for PRNG, in small blocks, where performance is poor,
+# and there may be problems with apps forking with open crypto
+# contexts, leading to failures.  The CBC ciphers work well:
+#CIPHERS=DES-CBC, DES-EDE3-CBC, AES-128-CBC, AES-192-CBC, AES-256-CBC
+
+# DIGESTS: either ALL, NONE, or a comma-separated list of digests to
+# enable [default=NONE]
+# It is strongly recommended not to enable digests; their performance
+# is poor, and there are many cases in which they will not work,
+# especially when calling fork with open crypto contexts.  Openssh,
+# for example, does this, and you may not be able to login.
+#DIGESTS = NONE
