loopdev.c, test_pager, and get_max_number_of_cpus() are linux-specific.
get_linux_version will only work on Linux, let's introduce
system_supports_ext4_ext2() which assumes that mounting ext2 with ext4
is not supported on non-Linux systems.

The commands echo(1) and printf(1) are usable for escape sequences
decoding, for example
for x in $(findmnt --noheading --raw --output TARGET); do
printf "%b" $x
done
but it's necessary to escape all '\' chars, otherwise for example \b
in foo\bar will be interpreted as backspace. It means that for example
findmnt(8) has to use \x5c for the backslash.
# findmnt --noheading --raw --output TARGET /dev/sda1
/mnt/ugly/foo\x5cbar

* use wcwidth() to count real number of columns required for
multibyte strings
* encode control characters with \x?? in raw and export (NAME=data) outputs
* use \x?? for controls and non-printable characters in the default outputs
* use \x?? to encode already existing hex sequences, for example
/mnt/ugly\x20space ---> /mnt/ugly\x5cx20space
this is not used in the default output, but in raw/export outputs
only (which is designed for scripts).

Missing semicolon made test_loop_info() to return function
loopcxt_enable_debug() return value, which happen to be void. I
suspect the loopcxt_enable_debug() was usually not executed, while it
should be.

We can not let the user control where TMPDIR is for this tempfile.
This will be where we write the updated passwd file, and must be
capable of being moved atomically with rename(2). Therefore, it
cannot be on a different device, or setpwnam() and vipw/vigr programs
will invariably fail with EXDEV.

Checking for the null byte at the end of the string only conditionally
leads to segfaults, evidenced by mount helpers crashing on writes to
/run/mount/utab. Simply check for the null on each iteration, and append
a null byte to the mangled string before breaking.

This reverts commit 6126f7a53c57485a9a29ddd772765695f23c92e6
and fixes the double open and leaking descriptor in a different way,
that is by using newly introduced function 'have_random_source()'
to check whether good random source is available while deciding
which uuid type to generate (random/time).
This is better than calling random_get_fd() twice, passing the file
descriptor down the stack and reusing it in next call to
random_get_fd().

We are opening /dev/urandom twice in uuid_generate(): first to check if
the file is available and then later __uuid_generate_random() again to
actually get the random data. Moreover, descriptor from the first open
is leaking.
Fix by passign the descriptor down the stack and reusing it there.

When some program' output exceeds the terminal's dimensions, it is a nice

on what libuuid provide. I did some modifications like avoid WIN32 checks - this
is util-LINUX.
[kzak@redhat.com: - move jrand_seed to lib/randutils.c
- use TLS for jrand_seed (like original code from libuuid)
- use size_t for buffer sizes
