The check tested whether code using crypt() links without -lcrypt, but
didn't set have_crypt to yes if it succeeded.
This fixes the check erroneously failing when compiling against musl
libc.

We already default to /lib for the default $exec_prefix, but the current
configure does not care about /lib64 although the use-case is exactly
same as for /lib.

* usable with --login to whitelist specified environment variables
* the list is ignored for the core variables like HOME, SHELL, USER,
LOGNAME and PATH (su --login always resets these variables)
Note that su(1) requires password and after successful authentication
user has full control over the session, so he can set arbitrary
environment variables. The whitelist makes things more user friendly
only.
The patch removes unnecessary optimization when allocate environ[]. It
seems better to keep all in glibc hands and just reset the environment
array only.

This is generic problem in all Python C code and gcc v8. The another
possible (and probably more correct) way is to add unused argument to
all API functions. Unfortunately, this solution is pretty invasive. The
question is if gcc is not too paranoid in this case.
For more details see https://bugs.python.org/issue33012. It seems
Python guys also prefer CFLAGS modification for now.

Nobody needs the .bz2 tarball. We dont't even upload it to
kernel.org.
BTW we fix dozens of these automake warnings:
automake-1.13/am/ltlibrary.am: warning: 'libblkid.la': linking libtool libraries using a non-POSIX
automake-1.13/am/ltlibrary.am: archiver requires 'AM_PROG_AR' in 'configure.ac'
So we can remove -Wno-portability. The only warning left is this
last GNU-make'ism which somebody may fix when reading it:
sys-utils/Makemodule.am:191: warning: addprefix sys-utils/,$(SETARCH_LINKS: non-POSIX variable name

cal: use ALTMON_* and _NL_ABALTMON_* constants to display
months in a standalone form correctly. These constants have just
been newly added to glibc. ALTMON_x has been used in BSD family
since 1990s and has been accepted as the future POSIX extension.
_NL_ABALTMON_* is exclusively a GNU extension but it is expected
to be added to POSIX in future.

The syscall swapon() with two arguments is supported since Linux 1.3.2

Linux network subsystem assigns an unique integer to a network
namespace.
term0# ip netns add UTIL-LINUX-LSNS-TEST-NS
term0# ip netns list
UTIL-LINUX-LSNS-TEST-NS
term0# ip link add name lsns-vetha type veth peer name lsns-vethb
term0 # ip link set lsns-vethb netns UTIL-LINUX-LSNS-TEST-NS
term0# ip netns list
UTIL-LINUX-LSNS-TEST-NS (id: 0)
term0# ip link show dev lsns-vetha
230: lsns-vetha@if229: <BROADCAST,MULTICAST> mtu 1500 qdisc noop ...
link/ether 3e:27:68:ba:b3:95 brd ff:ff:ff:ff:ff:ff link-netnsid 0
In this example 0 is assigned to UTIL-LINUX-LSNS-TEST-NS net namespace.
The name, UTIL-LINUX-LSNS-TEST-NS, and it semantics is given and defined
by iproute2 in userland; and nothing to do with util-linux.
However, the id, 0, is managed in linux kernel. If lsns can show
the ids, it helps users understand the state of network namespaces.
This commit adds NETNSID column to the output.
Here is an example of session:
term0# ip netns exec UTIL-LINUX-LSNS-TEST-NS cat
(Open another terminal)
term1# ./lsns --type net
NS TYPE NPROCS PID USER NETNSID COMMAND
4026531993 net 383 1 root unassigned /usr/lib/systemd/...
4026532433 net 1 1219 rtkit unassigned /usr/libexec/rtkit-daemon
4026532562 net 1 18201 root 0 cat
0 is shown as NETNSID for the cat process.
For the initial name space, "unassigned" is printed.
For the namespaces other type than net, "n/a" is printed.
If an error occurred during getting the id, "n/a" is printed.
Changes in V2:
* Remove wrongly used & operators.
* Make netnsid field empty if value for the column is not available.
Suggested by Karel Zak.
* Remove redundant condtion for checking the avaiablebility of netlink
socket. Suggested by Karel Zak.

The open() syscall is probably the most strong way how to check write
accessibility in all situations, but it's overkill and on some
paranoid systems with enabled audit/selinux. It fills logs with
"Permission denied" entries. Let's use eaccess() if available.

It seems some systems differentiate between tinfo and tinfow. And it
seems that mix ncursesw and tinfo (wide vs. non-wide char) is problem
for the systems.
Note that for example Fedora have ncursesw as well as ncurses, but
only one tinfo library. So, we need fallback this scenario.

The util-linux code was previously aligned to use @localstatedir@ and
the util-linux build system was set to override the default to use /run.
Current GNU Coding Standards introduced the @runstatedir@ variable
for this purpose. Lets use that instead.
The GNU default for @runstatedir@ is ${localstatedir}/run so util-linux
still override the default to be /run to preserve the status quo from
before. The only difference is that you'll now pass --runstatedir to
override the location on the command line instead of --localstatedir.
(FWIW, Debhelper in compat 11 will automatically start passing
--runstatedir=/run to all autotools configured builds. It already
passes --localstatedir=/var (to avoid it ending up with the GNU default
/usr/local/var) which breaks the util-linux build system code that
tries to default it to /run. This change will thus allow util-linux
and debhelper to work better together and avoid the need for a
package-specific override.)
Relevant historic commits:
* commit 07a16b9d1e
"build-sys: change --localstatedir to /run"
* commit 80c51185d5
"uuidd: use run configured state directory"
* commit 01c5b78794
"agetty: use configured run state directory"
[kzak@redhat.com: - add $runstatedir fallback for autoconf < 2.70
- check for unmodified $localstatedir]
