The --output-separator option will allow user to define table column
separator. This will allow for example to write back same delimeter as
which was used as input separator, for example
column -t -s : -o : /etc/passwd

This patch changes interpretation of subsequent delimeter interpretation.
Earlier version merged columns that had null string as content together,
which lead to output as visualized below.
$ printf "a🅱️c\n1::3\n" | column -t -s ':'
a b c
1 3
The number 3 has wrong column, which this patch takes care of, and alters
the output following way.
$ printf "a🅱️c\n1::3\n" | column -t -s ':'
a b c
1 3
This patch does not alter the default case, e.g., subsequent white spaces
are understood as separator of the same field, and the beginning of line
white spaces are being ignored together.

The --separator and --columns long options in util-linux-2.21.2 and in
a git clone from 5 minutes ago, don't work:
$ echo foobar | column -s x
foobar
$ echo foobar | column -c 10
foobar
$ echo foobar | column --separator=x
column: option '--separator' doesn't allow an argument
$ echo foobar | column --separator x
Segmentation fault
$ echo foobar | column --columns 10
column: bad columns width value: '(null)': Invalid argument
$ echo foobar | column --columns=10
column: option '--columns' doesn't allow an argument
Looks like a simple case of missing has_arg flag in the "struct
option" initialization for these two options. The patch just adds the
flag. I haven't done thorough testing of the patched code, but it
seems to work OK and it no longer segfaults or tries to dereference a
null pointer.

Solaris lacks err, errx, warn and warnx. This also means the err.h header
doesn't exist. Removed err.h include from all files, and included err.h from
c.h instead if it exists, otherwise alternatives are provided.

For the last line of the file lenght of line should be determined
where the EOF is instead of new line. Old output was
$ printf "1 2\n3" | column -t
column: line too long
1 2
which this commit will change to
$ printf "1 2\n3" | column -t
1 2
3

There has been unexpected mix of HAVE_WIDECHAR and ENABLE_WIDECHAR macros. The
ENABLE_WIDECHAR is old version and has to be replaced everywhere otherwise we
will see bugs with multibyte stuff.
