Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). The

problem was that one of the replacement routines had not been working since
SSLeay releases.  For now the offending routine has been replaced with
non-optimised assembler.  Even so, this now gives around 95% performance
improvement for 1024 bit RSA signs.

Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
*) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). The
problem was that one of the replacement routines had not been working since
SSLeay releases. For now the offending routine has been replaced with
non-optimised assembler. Even so, this now gives around 95% performance
improvement for 1024 bit RSA signs.

*) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
handling. Most clients have the effective key size in bits equal to
the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
