Stop defining _rpcsvcdirty in bss and data

_rpcsvcdirty is already defined in the generated code from rpcgen(1).

Detected during the build with Address Sanitizer (MKSANITIZER).

Sync usage with manpage. End it with a newline.

Add -4 and -6 options to rpd.lockd for consistent control over the
protocols to which it listens. As discussed on tech-userlevel.

convert __attribute__s to applicable cdefs.h macros

- pass lint (not completely)
- KNF
- ansify
- use %m instead of "%s, strerror(errno)" in syslog messages

Use a non-blocking SVC for TCP connections.

Clean up some include paths.

Implement file locking in lockd. All the stuff is done in userland, using
fhopen() and flock(). This means that if you kill lockd, all locks will

remote hosts will know it and re-establish the lock).
Tested against solaris 2.7 and linux 2.2.14 clients.
Shared lock are not handled efficiently, they're serialised in lockd when they
could be granted.

Supports nlm version 4 (for use with nfsv3).

Use pidfile(3).

WARNSify

NFS locking daemon by A.R. Gordon, ported from FreeBSD. While the
