I noticed a few issues while working with OpenLDAP that would lead to compiler
warnings and the like in our particular build environment. They're quite minor,
but it would still be good to have them patched upstream.

In include/ac/socket.h:

    Use #elif defined(...) for HAVE_WINSOCK and MACOS. All other instances
    of these macros use #ifdef or similar. A compiler may warn about them
    not being defined.

    In libraries/liblber/sockbuf.c, (DOS && PCNFS) and (DOS && NCSA) were
    replaced with HAVE_PCNFS and HAVE_NCSA, respectively. It seems logical
    to do the same at the only remaining occurrence of DOS, PCNFS, and NCSA.

For context on the latter: the actual warning was about #elif DOS, similar to
#elif HAVE_WINSOCK and #elif MACOS, but looking into it it seemed to make sense
to bring socket.h in line with sockbuf.c.

In libraries/liblunicode/ucdata/ucgendat.c:

    Use #if HARDCODE_DATA consistently, replacing two instances of #ifdef.
    HARDCODE_DATA is always defined, and this way you can set HARDCODE_DATA
    to 0 and have it work, rather than it going down the wrong branch and
    failing in these two cases.
