Two fixes:
1. If BIO_write() fails inside enc_write() it should return the
total number of bytes successfully written.
2. If BIO_write() fails during BIO_flush() it should return immediately
with the error code: previously it would fall through to the final
encrypt, corrupting the buffer.
bad, so let's not check OPENSSL_NO_ENGINE in those places. Fortunately, all
the header files where the problem existed include ossl_typ.h, which makes
a 'forward declaration' of the ENGINE type.
engine with something they claim is better. I have nothing to compare to,
and I assume they know what they're talking about. The interesting part with
this one is that it's loaded by default on OpenBSD systems.
This change was originally introduced in OpenBSD's tracking of OpenSSL.
des_old.h redefines crypt:
#define crypt(b,s)\
DES_crypt((b),(s))
This scheme leads to failure, if header files with the OS's true definition
of crypt() are processed _after_ des_old.h was processed. This is e.g. the
case on HP-UX with unistd.h.
As evp.h now again includes des.h (which includes des_old.h), this problem
only came up after this modification.
Solution: move header files (indirectly) including e_os.h before the header
files (indirectly) including evp.h.

was that they weren't really needed any more for EVP itself. However,
it seems like soma applications (I know about OpenSSH, but there may
be more) used evp.h as the 'load all' header file, which makes sense
since we try our best to promote the use of EVP instead of the lower
level crypto algorithms. Therefore, I put the inclusions back so
the application authors don't get too shocked by all the errors they
would otherwise get.
Thanks to Theo de Raadt for making us aware of this.
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.
CTR isn't included yet.
