Add new RPC code, based on Sun's TI-RPC code. Adapted to not use XTI,
but sockets instead, internally. Old, backward compatible interfaces
maintained.

Delint.
Remove trailing ; from uses of __weak_alias(). The macro inserts this if
needed.

remove unnecessary exit() after err()

descriptors against -1 (as appropriate).

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif

* make the initial xid a little more random (from freebsd)
* fix some spelos and tyops in comments (some from freebsd)
* use warn() instead of warnx() for many errors; the user probably
wants to know what the error code was.
