It looks like VPATH (split source and build directories) builds
are frequently broken. So let's test them on travis-ci.

Personally I use VPATH build in my deployment scripts.

struct in6_addr is both defined in the C library header <netinet/in.h>
and the Linux kernel header <linux/in6.h>.

lxc_user_nic.c includes both <netinet/in.h> and <linux/if_bridge.h>. The
later one includes <linux/in6.h>.

This breaks build with the musl libc:
  error: redefinition of ‘struct in6_addr’

As lxc_user_nic.c does not use any references from <linux/if_bridge.h> it
is safe to remove this header.

In many environments the preference is to configure containers with
apt mirrors that are SSL-secured.

When building containers using the download template this can't be
done unless an insecure mirror is first used to install the
apt-transport-https package, then the sources reconfigured to
use the https URL.

When building containers without using the download template this
can't be done unless the container creator specifically includes
this package in the package list at build time.

It seems more intuitive to me to have the package installed by
default. This patch includes the required package for the minbase
variant only as this is the default.

The idea here is that criu can use open_by_handle on a configuration which
will preserve inodes on moves across hosts, but shouldn't do that on
configurations which won't preserve inodes. Before, we forced it to always
be slow, but we don't have to do this.

If we don't do this, we'll end up changing the function signatures for the
internal __criu_* functions each time we add a new parameter, which will
get very annoying very quickly. Since we already have the user's arguments
struct, let's just pass that all the way down.

When writing out the CRIU exec command, we're bumping up against the buffer

If the value starts and ends with matching quote characters, those
characters are stripped automatically.   Quote characters are the
single quote (') or double quote (").  The quote removal is done after
the whitespace trimming.

This is needed particularly in order that lxc.environment values may
have trailing spaces.  However, the quote removal is done for all values
in the parse_line function, as it has non-const access to the value.

gentoo.moresecure.conf tries to drop the capability CAP_SYS_RESOURCES.
However, that capability doesn't exist, so the container doesn't start.
Change it to CAP_SYS_RESOURCE, according to capabilities(7).

gcc -Wall warns about uninitialized variables (-Wmaybe-uninitialized), and
-Werror makes it fatal. This change allows the build to succeed by NULL'ifying
the pointer passed to strtok_r().

Note that strtok_r(3) anyway ignores a non-NULL arg3 pointer on the 1st call
with non-NULL arg1 string.

- /etc(/rc.d)?/init.d/functions does not exist on all distributions
- LSB does not define a message function without an explicit status
- Debian-derived systems add a log_daemon_msg for that

lets define an own log_daemon_msg as echo and try to load LSB init
functions afterwards, which might overload it with a nicer version

that way the init scripts should work on any system, without hard
dependencies on neither LSB nor /etc/init.d/functions

pty logging only works correctly when stdout and stderr refer to a pty. If they
do not, we do not dup2() them and lxc_console_cb_con() will never write to the
corresponding log file descriptor.

When redirection on stdout and stderr is used we can safely assume that the user
is already logging to a file or /dev/null and creating an additional pty log
doesn't seem to make sense.

Note that is_crucial_subsystem still lists name=systemd.  That is
used in cgfs and cgmanager.  Cgmanager is typically setup to create
name=systemd, so it is ok.  cgfs uses is_crucial_subsystem() only
to decide whether failure to create or chown a directory should be
terminal.  That's ok, because (a) if name=systemd is not mounted then
we won't hit that, and (b) if name=systemd is mounted, then we'd
really still like to set it up for containers.

Using $(date) for LXC_GENERATE_DATE has various flaws:
* formating depends on the locale of the system we execute configure on
* the output is not really a date but more a timestamp

Let's use $(date --utc '+%Y-%m-%d') instead.

While at it, also support SOURCE_DATE_EPOCH [1] to make the build
reproducible
