The freopen(3) was replaced with fileargs_open(3) and fclose(3).
In the following function, we skip if the stream is standard in, so it is
safe to do so.
This also requires us to change the logic first to open the file and then
check its status. The stat(2) is disallowed in capability mode.
This commit unbrakes the -F option.
The bug was introduced in the r348708.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

trying to open files rather than giving up when it encounters an
error. ENOENT errors are not reported.
As a result, files that are moved away then recreated are not at
risk of being 'lost' to tail. Files that are recreated and
temporarily have unreadable permissions will be shown when they
are fixed.
This behaviour is consistent with the GNU version of tail but
without the verbiage that goes with the GNU version.
This change also fixes error messages accompanying -f and -F.
They no longer report problems with (null)!

This should fix the double free() bug where there's no tailing newline(\n)
character:
current# echo -n test | tail
