More EVP cipher revision.

Change EVP_SealInit() and EVP_OpenInit() to
handle cipher parameters.

Make it possible to set RC2 and RC5 params.

Make RC2 ASN1 code use the effective key bits
and not the key length.

TODO: document how new API works.

Also, corrects the linux-elf-arm config string, it was previously setting
$des_obj = dlfcn :-)

Declare ciphers in terms of macros. This reduces
the amount of code and places each block cipher EVP
definition in a single file instead of being spread
over 4 files.

* speed processes any/all options passed to it, not just one.
* DH and DSA have no "_get_method()" functions, only RSA does.
* typos.

not be used because it is not available on all systems (most notably,
win32).

There's no trace of it being implemented and it doesn't seem to have been
intended given that it is prototyped with a BIO yet there was a BIO-
specific version added in at the same time.

Remove duplicated code in EVP.

Second phase of EVP cipher overhaul.

Change functions like EVP_EncryptUpdate() so they now return a
value. These normally have software only implementations
which cannot fail so this was acceptable. However ciphers
can be implemented in hardware and these could return errors.

Beginnings of EVP cipher overhaul. This should eventually
enhance and tidy up the EVP interface.

This patch adds initial support for variable length ciphers
and changes S/MIME code to use this.

Some other library functions need modifying to support use
of modified cipher parameters.

Also need to change all the cipher functions that should
return error codes, but currenly don't.

And of course it needs extensive testing...

Call dh_tmp_cb with correct 'is_export' flag.

Avoid tabs in CHANGES.
