spin in a loop eating CPU time. This bug has existed since the
TI-RPC import. The problem is that we should only enter the select

servers.
Also improve/correct the code for cleaning up slave nfsd processes
and unregistering with rpcbind when the master nfsd exits.
One issue that remains open is that if a slave nfsd dies, then all
nfsds will shut down. This is because nfssvc() in the master nfsd
returns 0 when the master nfsd receives a SIGCHLD.

1) Allow the sending of more than one control message at a time
over a unix domain socket. This should cover the PR 29499.
2) This requires that unp_{ex,in}ternalize and unp_scan understand
mbufs with more than one control message at a time.
3) Internalize and externalize used to work on the mbuf in-place.
This made life quite complicated and the code for sizeof(int) <
sizeof(file *) could end up doing the wrong thing. The patch always
create a new mbuf/cluster now. This resulted in the change of the
prototype for the domain externalise function.
4) You can now send SCM_TIMESTAMP messages.
5) Always use CMSG_DATA(cm) to determine the start where the data
in unp_{ex,in}ternalize. It was using ((struct cmsghdr *)cm + 1)
in some places, which gives the wrong alignment on the alpha.
(NetBSD made this fix some time ago).
This results in an ABI change for discriptor passing and creds
passing on the alpha. (Probably on the IA64 and Spare ports too).
6) Fix userland programs to use CMSG_* macros too.
7) Be more careful about freeing mbufs containing (file *)s.
This is made possible by the prototype change of externalise.

At this point, the force option is only checked on detach, so it
would've been possible to allow the option to be passed with the
MDIOCDETACH operation. This was not done to allow the possibility of
having the force flag influence other tests in the future, which may

- Ask for user confirmation before adjusting to a head/cylinder
boundary (only when running interactively), and separate this
adjustment from the automatic calculation of c/h/s parameters.
- In sanitize_partition, don't change any values in the slice until
we know that the automatic adjustment will succeed.
- When auto-adjusting, ignore unused slices and give an appropriate
error for other zero-size slices depending on the cause.
- Change dos() to do all of the c/h/s calculations for a whole slice;
this fixes a bug where the ending c/h/s of an unused slice was set
incorrectly.
- When changing the active slice, detect the currently active slice
number instead of always defaulting to slice 4.
- Call fflush(stdout) before calling fgets().
- Test for fgets() returning NULL so we don't loop on EOF.
