This patch fixes further coding style issues where code should have
broken lines before operators in accordance with the GNU Coding
Standards but instead was breaking lines after them.
Tested for x86_64, and with build-many-glibcs.py.
* stdio-common/vfscanf-internal.c (ARG): Break lines before rather
than after operators.
* sysdeps/mach/hurd/setitimer.c (timer_thread): Likewise.
(setitimer_locked): Likewise.
* sysdeps/mach/hurd/sigaction.c (__sigaction): Likewise.
* sysdeps/mach/hurd/sigaltstack.c (__sigaltstack): Likewise.
* sysdeps/mach/pagecopy.h (PAGE_COPY_FWD): Likewise.

An attempt to re-create a different PTY under the same name can fail
if the PTY has a very high number. Try to increase the file
descriptor limit in this case, and bail out if this still does not
allow the test to proceed.

* sysdeps/unix/sysv/linux/tst-ttyname.c (do_in_chroot_1): Skip the
test instead of failing in case of ENOENT returned by posix_openpt.

On Fedora, the previous initialization sequence did not work and
resulted in failures like:
info: entering chroot 1
info: testcase: basic smoketest
info: ttyname: PASS {name="/dev/pts/5", errno=0}
info: ttyname_r: PASS {name="/dev/pts/5", ret=0, errno=0}
error: ../sysdeps/unix/sysv/linux/tst-ttyname.c:122: write (setroups, "deny"): Operation not permitted
info: entering chroot 2
error: ../sysdeps/unix/sysv/linux/tst-ttyname.c:122: write (setroups, "deny"): Operation not permitted
error: 2 test failures

Add a new tst-ttyname test that includes several named sub-testcases.
This patch is ordered after the patches with the fixes that it tests for (to
avoid breaking `git bisect`), but for reference, here's how each relevant change
so far affected the testcases in this commit, starting with
15e9a4f378c8607c2ae1aa465436af4321db0e23:

[1]: 15e9a4f introduced a semantic that, under certain failure
conditions, ttyname sets errno=ENODEV, where previously it didn't
set errno; it's not quite fair to hold "before 15e9a4f" ttyname to
those new semantics. This testcase actually fails, but would have
passed if we tested for the old the semantics.
Each of the failing tests before 15e9a4f are all essentially the same bug: that
it returns a PTY slave with the correct minor device number, but from the wrong
devpts filesystem instance.
15e9a4f sought to fix this, but missed several of the cases that can cause this
to happen, and also broke the case where both the erroneous PTY and the correct
PTY exist.
