python-lxc: follow global rpath setting for autotools builds

When LXC is configured with --enable-rpath, I expect Python bindings
to be able to find the library in a non-standard location, just like
LXC command-line tools.

Move apt-transport-https to global packages_template

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.

Commit 396f75ab added the package
to the minbase variant, but this variant is not used by the download
template build process. The build process instead specifies no
variant, so this patch moves the package from the packages_template
package list in the minbase variant to the global packages_template
package list, ensuring that this package is included in all Ubuntu
build images that use the lxc-ubuntu template.

start containers in foreground when using the lxc@.service

lxc-start started to default to daemonize the container when starting
this conflicts with type=simple of the systemd unit

call lxc-start with -F and thus force execution in foreground
that way we can feed the log to journald properly and keep type=simple

python-lxc: use setuptools instead of distutils

setuptools is recommended by Python Packaging Guide
https://python-packaging-user-guide.readthedocs.io/en/latest/current/

It contains some useful extensions like 'develop' command. Also it
is required for building wheels AFAIK.

The only downside is an extra build-time dependency. setuptools are
packaged in both Debian and Ubuntu (python3-setuptools), as well as
other major distros, so it shouldn't be an issue, I think.

python-lxc: change distribution name _lxc -> lxc

Distribution name starting with underscore is considered invalid by

travis: test VPATH builds

python-lxc: enable standalone builds

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.

Fix redefinition of struct in6_addr

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.

Add apt-transport-https to minbase variant packages_template

It seems more intuitive to me to have the package installed by

Dont force irmap

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.

log: remove duplicate definitons and bump buffer size

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
size limit. Let's increase it so we can avoid:

Allow configuration file values to be quoted

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.
