Manual pages: runuser.1, su.1: miscellaneous wording and formatting fixes
Various wording and formatting fixes. Nothing too contentnious, I think,
so I rolled these changes into one patch.
Since there is much common text in su.1 and runuser.1, I've combined
the changes to both pages into one patch, and, as far as possible,
ensured that changes to the common pieces of text match across the
two pages.

rename: fix regression for symlink with non-existing target
Since commit 5454df9c3110 ("rename: check source file access early")
rename fails early for symlinks with non-existing target (regression),
because access() dereferences the link.
From access(2):
"access() checks whether the calling process can access the file pathname.
If pathname is a symbolic link, it is dereferenced."
Thus replace access() with faccessat() and lstat() as fallback,
(as in do_symlink()), that is equivalent for symlink and files.
From fsaccess(2) and stat(2):
"The faccessat() system call operates in exactly the same way as access(),
except for the differences described here.
[...]
If pathname is relative and dirfd is the special value AT_FDCWD, then pathname
is interpreted relative to the current working directory of the calling process
(like access()).
[...]
AT_SYMLINK_NOFOLLOW
If pathname is a symbolic link, do not dereference it:
instead return information about the link itself."
"lstat() is identical to stat(), except that if pathname is a symbolic link, then
it returns information about the link itself, not the file that it refers to."
Testing
-------
1) symlink with existing target
2) symlink with non-existing target
3) non-existing symlink
4) existing file
5) non-existing file
$ ./rename found existing file-not-found # XFAIL.
rename: file-not-found: not accessible: No such file or directory
$ echo $?

And to test/simulate faccessat()'s EINVAL for AT_SYMLINK_NOFOLLOW
for Mac OS X, per commit 826538bf64c5 ("rename: skip faccessat()
failure if AT_SYMLINK_NOFOLLOW is not a valid flag"), forced 'if'
to evaluate to false so that lstat() is taken.
It still fails early; the error messages are slightly different
('not accessible' vs. 'stat of ... failed') but still tell same
'No such file or directory'; exit code is the same as well.
$ ./rename sym symbolic- symlink-3 # XFAIL. DIFF MSG/SAME RC.
rename: stat of symlink-3 failed: No such file or directory

cryptsetup: add option to use via dlopen in libmount
Enabling libcrypsetup in libmount had several unintended side
effects.
First of all, it increases the Debian minimal image size by
~2.5% (5.6MB worth of new libraries).
Then, due to libcryptsetup linkage to OpenSSL and libjson-c,
it causes incompatibilities with external programs linking
against both libmount and a private, static, old version of
OpenSSL, or external programs linking against libjansson or
json-glib, which have one symbol in common with libjson-c.
If ./configure is ran with --with-crypsetup=dlopen,
instead of linking to libcrypsetup, use dlopen to resolve
the symbols at runtime only when the verity feature is
used, thus avoiding clashes and keeping images size down.

chfn: Make readline prompt for each field on a separate line
When readline is called to get user input, it is called without
a prompt argument. As a result, if the user does not enter anything
for a given field, then the next field is displayed on the same
line, yielding the following output:
$ chfn
Changing finger information for user.
Password:
Name []: Office []: Office Phone []: Home Phone []:
instead of the expected:
$ chfn
Changing finger information for user.
Password:
Full Name []:
Room Number []:
Work Phone []:
Home Phone []:
This patch restores the expected behavior by feeding readline with
a character to display as "prompt".

To judge from fc412fe4cee960, back in 2016 it was the latest version
of Ubuntu available on Travis CI. Now build tools there are too old
for testing purposes.
Other than that, Ubuntu Trusty hasn't been supported at https://apt.llvm.org/
since August 2019, which makes it kind of hard at this point to bring the latest clang
along with ASan, UBsan, Msan and libFuzzer to Travis CI.

The test assumed that / was a mountpoint. This is not always the case, for

mountpoints are found.
Split two long lines, adding '\e' at the end of the first part,
