5b42dac8ec Most modern OSs have the ability to flag certain mounts as ones to
be ignored by default by the df(1) program.  This is used mostly to
avoid stat()-ing entries that do not represent "real" disk mount
points (such as those made by an automounter such as amd.)  It is
also useful not to have to stat() these entries because it takes
longer to report them that for other file systems, being that these
mount points are served by a user-level file server and resulting in
several context switches.  Worse, if the automounter is down
unexpectedly, a causal df(1) will hang in an interruptible way.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

2ffc1ec6ca The manual page of df called cd9660 file systems by the name
isofs while the df command itself used the name iso9660fs or
        cdfs. Both of these were inconsistent with the name cd9660 which
        is used by the mount command. I modified df to recognize all of
        the names cd9660, cdfs, isofs, and iso9660fs, and take them all
        to refer to the same thing. Naturally I added a note of this
        behaviour in the manual page too.

51ea8b57b8 Partially fixed negative and truncated "Avail" counts in df output.
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.

0fd510b71a You will find enclosed some changes to make gcc -Wall more happy in
/usr/src/bin. Note that some patches are still needed in that directory.

I (Joerg) finished most of Philippe's cleanup.  /bin/sh will still
need *allot* of work, however.

9d4081ee4b The last commit was bogus...the putenv doesn't affect the parent process,
so the BLOCKSIZE doesn't need to be preserved.
Also initialized the flags variables, and used 1k instead of 1024 for
BLOCKSIZE.
