Deprecate the low level DES functions.

Use of the low level DES functions has been informally discouraged for a
long time. We now formally deprecate them.

Applications should instead use the EVP APIs, e.g. EVP_EncryptInit_ex,
EVP_EncryptUpdate, EVP_EncryptFinal_ex, and the equivalently named decrypt
functions.

Reorganize local header files

Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like

'*_lcl.h', '*_local.h', or '*_int.h'

This commit changes the different suffixes to '*_local.h' uniformly.

Experimental symbol renaming to avoid clashes with regular OpenSSL.

Make sure crypto.h is included first in any affected files.

Because of recent reductions in header interdependencies, these files need
to include crypto.h directly.

Cleanse memory using the new OPENSSL_cleanse() function.
I've covered all the memset()s I felt safe modifying, but may have missed some.

Make the change to strong keys in the string to key(s) functions experimental in the main trunk as well

Apply one patch from Assar Westerlund <assar@sics.se>:

The following patch makes sure that string2key does not use weak DES
keys (then making them non-weak by xor:ing with 0xF0).

libdes (which is still used out there) or other des implementations,

Due to an increasing number of clashes between modern OpenSSL and
libdes (which is still used out there) or other des implementations,
the OpenSSL DES functions are renamed to begin with DES_ instead of
des_. Compatibility routines are provided and declared by including
openssl/des_old.h. Those declarations are the same as were in des.h
when the OpenSSL project started, which is exactly how libdes looked
at that time, and hopefully still looks today.

The compatibility functions will be removed in some future release, at
the latest in version 1.0.

Make EVPs allocate context memory, thus making them extensible. Rationalise
DES's keyschedules.

I know these two should be separate, and I'll back out the DES changes if they
are deemed to be an error.

Note that there is a memory leak lurking in SSL somewhere in this version.

Add functions des_set_key_checked, des_set_key_unchecked.
Never use des_set_key (it depends on the global variable des_check_key),
but usually des_set_key_unchecked.
Only destest.c bothered to look at the return values of des_set_key,
but it did not set des_check_key -- if it had done so,
most checks would have failed because of wrong parity and
because of weak keys.

Change type of various DES function arguments from des_cblock
(meaning pointer to char) to des_cblock * (meaning pointer to
array with 8 char elements), which allows the compiler to
do more typechecking. (The changed argument types were of type
des_cblock * back in SSLeay, and a lot of ugly casts were
used then to turn them into pointers to elements; but it can be
done without those casts.)

Introduce new type const_des_cblock -- before, the pointers rather
than the elements pointed to were declared const, and for
some reason gcc did not complain about this (but some other
compilers did).
