Subject: OMP support in PDF format is done

Hi,

Finally, after many hours of debugging I got OMP support in PDF format
working. It is not heavily tested.

commit de528ee9f0a066acd5fd44b1fc8dc7c3a74d00df

    Add OMP support in PDF format.

    $ ../run/john -fo:pdf -t # 1 core
    Benchmarking: PDF MD5 RC4 [32/64]... DONE
    Many salts: 34973 c/s real, 34973 c/s virtual
    Only one salt:      34966 c/s real, 34966 c/s virtual

    $ ../run/john -fo:pdf -t # 3 cores
    Benchmarking: PDF MD5 RC4 [32/64]... (3xOMP) DONE
    Many salts: 103488 c/s real, 34844 c/s virtual
    Only one salt:      103104 c/s real, 34598 c/s virtual

    Passware gets slightly better numbers (~108K c/s using 3 cores)

Thanks to Jim for the tips! Passware gets slightly better numbers. Can
we beat Passware?

PDF AES support is next on my list.
