Add a dummy target for `builtins' in the Makefile, to prevent it
from attempting to build this file by compiling builtins.c. :-/
This fixes PR943.
ffs/ffs_vfsops.c:
ffs_statfs() multiplied by (100 - minfree) as part of calculating the
minfree percentage (complemented in 100%), so with the standard minfree
of 8, it was broken for file systems of size >= 1TB/92 = 11GB. Use the
standard freespace() macro instead. This also fixes a rounding bug (the
"Avail" count was sometimes 1 too small).
ffs/* (not fixed):
The freespace() macro multiplies by minfree, so with the standard
minfree of 8, it is broken for file systems of size >= 1TB/8 = 128GB.
This bug is more serious since it affects block allocation.
ffs/ffs_alloc.c (not fixed):
Ordinary users are sometimes allowed to allocate 1 (partial) block
too many so that the "Avail" count goes negative. E.g., if there is
1 fragment available and the file is fairly large, one more full
block is allocated.
df/df.c:
ufs_df() used/uses essentially the same code as ffs_statfs(), so it
had/has the same bugs.
ufs_df() gratuitously replaced "Avail" counts of < 0 by 0, so it
gave different results for non-mounted file systems in this case.

`-u' and grepping for the username. Basically you can now get a short
`ps -x' like list (with more space for the command) for other users.

Fixes also an earlier problem report about the shell not evaluating
loops correctly. (Not files via GNATS.)

This means that a script containing:
echo 1
set -v
echo 2
will now produce output, like it does on SYSV machines and other 'proper'
/bin/sh implementations..
This is done by a slight restructure of the input processor allowing it to
read chunks from the file at a time, but process the data by line from the
chunk.

command and badly needed in sh(1) for everybody who wants to modify
the system-wide limits from inside /etc/rc.
The options are similar to other system's implemantations of this
command, with the FreeBSD additions for -m (memoryuse) and -p (max
processes) that are not available on other systems.
`mv foo/ ../..' to `mv foo/ ../../foo/', not to `mv foo/ ../../'. The
latter caused a panic. Before the trailing slash changes in the kernel,
the trailing slashes caused the rename() for this mv to fail earlier, so
there was no panic in 2.0.
Fixes part of PR 760.
