The way the kernel namespaces have been implemented breaks assumptions
udev made regarding uevent sequence numbers. Creating devices in a
namespace "steals" uevents and its sequence numbers from the host. It
confuses the "udevadmin settle" logic, which might block until util a
timeout is reached, even when no uevent is pending.
Remove any assumptions about sequence numbers and deprecate libudev's
API exposing these numbers; none of that can reliably be used anymore
when namespaces are involved.

If -flto is used then gcc will generate a lot more warnings than before,
among them a number of use-without-initialization warnings. Most of them
without are false positives, but let's make them go away, because it
doesn't really matter.

In trying to track down a stupid linker bug, I noticed a bunch of
memset() calls that should be using memzero() to make it more "obvious"
that the options are correct (i.e. 0 is not the length, but the data to
set). So fix up all current calls to memset(foo, 0, length) to
memzero(foo, length).

Note: udev_builtin_net_setup_link has *not* been imported. Also
still missing from udev-builtin is udev_builtin_uaccess.

sys/poll.h is a legacy alias used by glibc.
according to POSIX #include <poll.h> is correct.
on GLIBC, the POSIX header includes sys/poll.h, so everything
continues working as it should.

This commit imports strxcpyx from upstream. This is upstream commit
d5a89d7dc17a5ba5cf4fc71f82963c5c94a31c3d
Note: there were also some very minor code cleanups to
accelerometer.c: line 187
collect.c: lines 35, 140
libudev-device.c: line 780
libudev-hwdb.c: line 300
These are part of upstream commits:

This code was accidentally removed in commit
601c4e8ce69338652b3c9178386cbc05de8bae8d
We restore it here. Since most modern systems have accept4()
this code will seldom be triggered. You can test by configuring
as follows:
ac_cv_have_decl_accept4="no" ./configure

Avoid "sender uid=65534, message ignored" case, where no credentials can
be read on the sender side.
Seems, the server socket does not enable credential receiving fast
enough, and the message from the client (without credential) sometimes
is queued before the credential passing was active.

Commit ff2c503df091e6e4e9ab48cdb6df6ec8b7b525d0 introduced accept4() into
udev, which broke compatibility with kernels older than Linux 2.6.32 (or
Linux 2.6.36 on ARM). The purpose of accept4() is to permit
O_NONBLOCK and O_CLOEXEC to be specified at the accept() call site
while previously, they had to be set using fcntl() because Linux does
not inherit them.
Since accept4() increases the minimum kernel version, we add a fallback
path for situations in which it is unavailable.
