A number of includes were removed from evp.h some time ago.  The reason 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.
