spares (the size of the field was changed from u_short to u_int to
reflect what it really ends up being). Accordingly, change users of
xucred to set and check this field as appropriate. In the kernel,
this is being done inside the new cru2x() routine which takes a
`struct ucred' and fills out a `struct xucred' according to the
former. This also has the pleasant sideaffect of removing some
duplicate code.

been patched so many times it was a bit of a mess. There are style,
code and man page cleanups. The following are the functional changes:
The RFC only permits the returning of 4 possible error
codes, make sure we only return these (PR 27636).
Use MAXLOGNAME to determine the longest usernames.
Add a -i flag, which returns the uid instead of the username
(this is from a PR 25787, which also contained alot of the
cleanups in this patch).

The patch I used isn't quite the one Lars suggested, but the size
of the largest datagram you can recv isn't #defined anywhere, and
probably isn't even bounded for some protocols.

actually in the kernel. This structure is a different size than
what is currently in -CURRENT, but should hopefully be the last time
any application breakage is caused there. As soon as any major
inconveniences are removed, the definition of the in-kernel struct
ucred should be conditionalized upon defined(_KERNEL).
This also changes struct export_args to remove dependency on the
constantly-changing struct ucred, as well as limiting the bounds
of the size fields to the correct size. This means: a) mountd and
friends won't break all the time, b) mountd and friends won't crash
the kernel all the time if they don't know what they're doing wrt
actual struct export_args layout.

variable used was a int, which is only 32-bits. Use size_t as the type
for 'len' to work-around this.
Some inetd internal udp servers didn't worked with problem.
Also fix recvfrom() "fromlen" arg type from int * to socklen_t *.

it, I'll make it configurable.
