Integrate changes 7819,7820 from vmsperl into mainline.
Add header for LIB$ prototypes (C. Berry) Convert fwrite()s to sockets to write()s, since some socket stacks don't take kindly to stdio. Ignore "expected" SS$_NOLOGNAM when doing internal LNM lookups (for often optional LNMs) Correct a few typos (C. Bailey) p4raw-id: //depot/perl@8724
