TAP::Parser::Aggregator::has_errors may return any number, not just 0
and 1.  With Perl on VMS, any number from 2 and on is interpreted as a
VMS status, the 3 lower bits are the encoded severity (1 = SUCCESS,
for example), so depending on what has_errors returns, a test failure
might be interpreted as a success.  Therefore, it's better to make
sure the exit code is 0 or 1, nothing else (they are special on VMS,
and mean SUCCESS or FAILURE, to match Unix conventions).

VMS renames our libraries to fit VMS conventions.  This must be accounted

    Clarify use of |$end0| in stitched x86-64 AES-GCM code.

    There was some uncertainty about what the code is doing with |$end0|
    and whether it was necessary for |$len| to be a multiple of 16 or 96.
    Hopefully these added comments make it clear that the code is correct
    except for the caveat regarding low memory addresses.

The way try_decode_params works in raw more, it would take the first ASN1

This change has it go through all the matching ASN1 methods and properly
