Remove from the printfns the assumption that dp->list != NULL. Even
if there are no entries, these functions may be called to print the

Treat filenames as multibyte character strings (according to the current
LC_CTYPE setting) when determining which characters are printable.
This is an often-requested feature.

Use wcwidth() to determine the number of column positions a character
takes up, although there are still a few places left where we assume
1 byte = 1 column position, e.g. line-wrapping when handling the -m option.

The error handling here is somewhat more complicated than usual: we do
our best to show what we can of a filename in the presence of conversion
errors, instead of simply aborting.

Fixes to output of `ls -lh` for certain file sizes:
1. Sizes in the range 1000 -- 1023 units require four characters width
for the integer; increase the field width to accomodate this.
2. Sizes in the range 9.95 -- 10 units were being displayed as "10.0"
units; adjust the logic to fix this, and now that we've got an extra
character of field width, print fractional units if the size is less
than 99.95 units.
3. Don't display sub-byte precision.

This should mean that the following sizes are displayed:
0B .. 1023B
1.0U .. 9.9U
10.0U .. 99.9U
100U .. 1023U
for values of U in "KMGTPE".

Teach "ls -Z" to use the policy-agnostic MAC label interfaces rather
than the LOMAC-specific interfaces for listing MAC labels. This permits
ls to view MAC labels in a manner similar to getfmac, when ls is used
with the -l argument. Next generation LOMAC will use the MAC Framework
so should "just" work with this and other policies. Not the prettiest
code in the world, but then, neither is ls(1).
