Better support for PDS members in z/OS C library

The z/OS C library has poor support for PDS and PDS/E.

Specifically, when using fopen() to read or write members, there are no facilities to:

1) obtain existing user directory entry info (read and write)
2) update user directory info (write)
3) support for DISP=SHR plus ISPF Enqueue serialization

The first two of these cannot be easily worked around by user code without completely abandoning the use of the C-library for I/O.

    Don't forget to include support for PDSE Member Generations.

    I believe this also limits the use of "/bin/cp any.file "//PREFIX.PDS(MEMBER)" when a SHR
    allocation for "PREFIX.PDS" exists. That's often been a nuisance to me. /bin/cp should
    employ SPFEDIT-style serialization for PDS members.

    Thsnks,
