Justin T. Gibbs c2c5fd345d aic7xxx.seq:
Fix support for the aic7850 by looking only at the relavent bits of the
    QINCNT.  The 7850 puts random garbage in the high bits and all my attempts
    to determine the cause of this failed.  This approach does seem to work
    around the problem.

    Don't trust SCSIPERR to tell us when there is a parity error.  On
    some revs of the 7870 and the 7880, this bit follows the parity of
    the current byte.  Instead of using a SEQINT to tell the kernel,
    re-enable the standard parity error interrupt since it seems to pause
    the sequencer right at the time of the error which is the effect we were
    looking for anyway.

aic7xxx_reg.h:
    Remove PARITY_ERROR seqeuncer interrupt type, its no longer used.

    Define QCOUNTMASK as the SRAM location for the mask to use on the
    QINCNT register.  QCOUNTMASK is determined by the number of SCBs
    supported by the device we're working on.

aic7xxx_asm.c
    Properly check the return value of fopen, and define the arg list
    in getopt correctly.
