Add some more tests:
* error handling "unknown arch" and "unknown command"
* "noop" test with host arch and no other options
* all options except --uname-2.6
* --uname-2.6 whithout any other options but handle fatal
glibc error "kernel too old" (with debug output)
* add a "real" --uname-2.6 test which validates uname(1)
output
Note the "kernel too old" cases are systems where glibc was
configured to support only kernels > 3.0. On some archs
(e.g. x86) --uname-2.6 still works with such glibc because
2.6.39 had all needed features on board (e.g. vdso).

Some people reported segfaults (after execvp) but I can only
reproduce it on arm* and aarch64 qemu-user-space builds. We
don't need to fix our tests for such broken systems where
also many other tests fail currently.

lscpu: correct the Virtualization type on Xen DomU PV guest
Nowadays, most Intel CPUs have "cpuid faulting" available which could trap
the execution of "cpuid" instruction when CPL>0 with GP fault. Thus,
"cpuid" instruction could trap to Xen hypervisor on the paravirtualized PV
guest on most servers today, except on old CPUs prior to 2011. On CPU after
2011, Xen will put "XenVMMXenVMM" on both HVM and PV guests, which could
have lscpu command erroneously classify the guest as type "full". The
current lscpu command, which is based on "cpuid" instruction, still assumes
that it will not cause the trap to Xen hypervisor on Xen PV guest and uses
/proc/xen to identify whether it's running on PV DomU or not. To identify
this kind of information under the help of
/sys/hypervisor/properties/features would be more accurate for the CPU
nowadays. The bit 5 (XENFEAT_mmu_pt_update_preserve_ad) of the features
will be set only when it's running on Xen PV domain. The combo of bit 3 and
8 (XENFEAT_supervisor_mode_kernel and XENFEAT_hvm_callback_vector) will be
set simultaneously only when it's running on Xen PVH domain.

swapon: rewrite control struct usage
The old version has been pretty broken... the most important is to
keep swap options specified on command line as read-only template.
For example if we call "swapon --all" then we cannot modify the global
options for each fstab swap entry.
The another story has been control struct modification due to device
reinitialization etc.
This patch splits all to:
* struct swapon_control; top-level struct with command line options
* struct swap_device; this is device specific and never globally
maintained by swapon_control.
* struct swap_prop; used as global read-only template swap options
and per device swap options (when parse fstab).

swapon: fix discard=pages docs
The documentation for discard=pages is ambiguous in that it could be
interpreted to mean either that the pages are discarded immediately
after being freed or that the pages are discarded immediately before
being reused by a write. Both implementations would satisfy the
statement "discard freed swap pages before they are avaliable for
reuse", but the kernel does the former.
Doing a discard operation (which is non-queued on SATA drives before
SATA 3.1) before a write operation to the same sector is pointless
unless using, pre-SATA 3.1 drives, where discard is detrimental because
ATA TRIM is a non-queued command.
Anyone who wants discard operations on swap and interprets the man page
as describing the incorrect behavior would opt for discard=once over
discard, when discard provides the behavior of both discard=once and
discard=pages, which is what they likely want.
Lets make a small change to the documentation to clarify the behavior.

travis: add OSX build
Of course OSX is not an important target but since it's available on
travis we can (mis)use it to generally improve non-Linux and non-GNU
compatibility. People are using musl, busybox or whatever and
util-linux should work for them. Having OSX build running regularly
will help us to freeze the lately improved BSD compatibility and
to check code which is usually ifdef'ed.
We are using the most recent OSX 10.11.x / Xcode 7.3 though the older
travis OSX images are working too currently.
If it turns out that this OSX build is too annoying when we are about
to add support for latest Linux features then we could add:
allow_failures:
- os: osx
to let it fail silently.
Note I've tried hard to keep .travis-functions.sh readable for the
Linux case. I've removed --with-python because it's default anyway,
--enable-gtk-doc is still tested in discheck.
OSX root check would also work (almost, using another --prefix) but
would only run one more test yet (minix).
OSX distcheck would have some issues with conditionally built man
pages and does not work with default distcheck confopts. No need to
fix that because distcheck is more for maintainer machines.
BTW to increase travis build speed again we could remove some targets
from the matrix without losing tested scenarios:
- nonroot for Linux seems to be waste of time
- clang/Linux could be root check only
For now we keep it as is.
