[PATCH v3 0/6] Fixup linux ttyname and ttyname_r [BZ #22145]

[Luke Shumaker]

The theme of this patchset is to fixup the changes made in 15e9a4f.
Fix a bug [BZ #22145] introduced in the commit (and add tests for both
the bug it fixed and the bug it introduced!), update documentation to
reflect the behavior introduced in the commit.

The FSF should have my copyright assignment paperwork on file (though
I never received a confirmation from them that everything was in
order).

v2:
 - See individual commit messages
v3:
 - Revise commit messages
 - Revise ChangeLog messages
 - Split one of the commits in to 2 separate commits
 - Fix style of comments (no "*" on continued lines, 2 spaces after
   trailing period)
 - Fix whitespace style in the definition of is_mytty
