7cfcca8ba3 Further FIPS algorithm blocking.
Fixes to cipher blocking and enabling code.

Add option -non-fips-allow to 'enc' and update testenc.

d0edffc7da FIPS algorithm blocking.
Non FIPS algorithms are not normally allowed in FIPS mode.

Any attempt to use them via high level functions will return an error.

The low level non-FIPS algorithm functions cannot return errors so they
produce assertion failures. HMAC also has to give an assertion error because
it (erroneously) can't return an error either.

There are exceptions (such as MD5 in TLS and non cryptographic use of
algorithms) and applications can override the blocking and use non FIPS
algorithms anyway.

For low level functions the override is perfomed by prefixing the algorithm
initalization function with "private_" for example private_MD5_Init().

For high level functions an override is performed by setting a flag in
the context.

b0ea8b160c It was pointed out to me that if the requested size is 0, we shouldn't
ty to allocate anything at all.  This will allow eNULL to still work.

18eda73234 EVP_EncryptInit_ex() and EVP_DecryptInit_ex() had been defined in evp.h but
not implemented. (Bug reported by Martin Szotkowski)

This also changes the non-"_ex" versions to defer directly to
EVP_CipherInit_ex() rather than EVP_CipherInit() to avoid an unecessary
level of indirection.

11a57c7be5 This changes EVP's cipher and digest code to hook via the ENGINE support.
See crypto/engine/README for details.

- it also removes openbsd_hw.c from the build (that functionality is
  going to be available in the openbsd ENGINE in a upcoming commit)

- evp_test has had the extra initialisation added so it will use (if
  possible) any ENGINEs supporting the algorithms required.

Worth around 5% for encrypt. Slows down decrypt slightly, but I expect to
regain that later.

be06a9348d 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.

7f0606016c 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...

9cb0969f65 Fix version stuff:
1. The already released version was 0.9.1c and not 0.9.1b

2. The next release should be 0.9.2 and not 0.9.1d, because
   first the changes are already too large, second we should avoid any more
   0.9.1x confusions and third, the Apache version semantics of
   VERSION.REVISION.PATCHLEVEL for the version string is reasonable (and here
   .2 is already just a patchlevel and not major change).
