Fix new -aes command argument handling

Make the engine config module always add dynamic ENGINEs
to the list using dynamic_path. This stops ENGINEs which
don't supply any default algorithms being automatically
freed (because they have no references) and allows them
to be accessed by id.

Alternative dynamic loading behaviour can be achieved by
issuing the dynamic ENGINE ctrls separately in the config file.

when OpenSSL_add_all_algorithms() is called.

CONF_modules_unload() now calls CONF_modules_finish()
automatically.

Default use of section openssl_conf moved to
CONF_modules_load()

Load config file in several openssl utilities.

Most utilities now load modules from the config file,
though in a few (such as version) this isn't done
because it couldn't be used for anything.

In the case of ca and req the config file used is
the same as the utility itself: that is the -config
command line option can be used to specify an
alternative file.

This is especially important for AES that has a 16 bytes IV.

comparison doesn't look right, but at least it compiles.  It would be nice
if the one who knows what this is supposed to do changed it to do it correctly

let's recommend running config instead of a manual Configure.

Also, with the change in Configure, it now knows on it's own if
threads are supported or not.

deviates from the "standard" 64 bits of feedback that all other
algorithms are using.  Therefore, let's redo certain EVP macros to
accept different amounts of feedback bits for these modes.

Also, change e_aes.c to provide all usually available modes for AES.

so do not add one after the expansion, since ANSI C doesn't allow ;;
at this level (or at least, so tells me gcc).
