Remove outdated legacy crypto options

Many options for supporting optimizations for legacy crypto on legacy
platforms have been removed.  This simplifies the source code and
does not really penalize anyone.
        DES_PTR (always on)
        DES_RISC1, DES_RISC2 (always off)
        DES_INT (always 'unsigned int')
        DES_UNROLL (always on)
        BF_PTR (always on) BF_PTR2 (removed)
        MD2_CHAR, MD2_LONG (always 'unsigned char')
        IDEA_SHORT, IDEA_LONG (always 'unsigned int')
        RC2_SHORT, RC2_LONG (always 'unsigned int')
        RC4_LONG (only int and char (for assembler) are supported)
        RC4_CHUNK (always long), RC_CHUNK_LL (removed)
        RC4_INDEX (always on)
And also make D_ENCRYPT macro more clear (@appro)

This is done in consultation with Andy.

-     * The original reason for implementing this(*) was the fact that

-     * and e.g. a byte store has to be done with 64-bit load, shift,
-     * and, or and finally 64-bit store. Peaking data and operating
-     * at natural word size made it possible to reduce amount of
-     * instructions as well as to perform early read-ahead without
-     * suffering from RAW (read-after-write) hazard. This resulted
-     * in ~40%(**) performance improvement on 21064 box with gcc.
-     * But it's not only Alpha users who win here:-) Thanks to the
-     * early-n-wide read-ahead this implementation also exhibits
-     * >40% speed-up on SPARC and 20-30% on 64-bit MIPS (depending
-     * on sizeof(RC4_INT)).

-     *      and output pointers appear to be aligned at natural CPU
-     *      word boundary

-     *   (2.5-3 times slower than one generated by Sun's WorkShop
-     *   C) and therefore gcc (at least 2.95 and earlier) should
-     *   always be told that RC4_CHUNK="unsigned long".
