check pthread_atfork and thread-local storage

Add pthread_atfork check to configure.ac and uses it when necessary,
Introduces tls.m4 macro for checking thread-local storage support, Puts
values array into thread-local storage
(lxc_global_config_value@src/lxc/utils.c), Removes
static_lock/static_unlock from LXC code.

Lastly, it introduces a warning for bionic users about multithreaded
usage of LXC.

rename lxc-stop shutdown argument to nokill

This makes the arguments between lxc-stop and lxc-autostart more
consistent, so that --shutdown doesn't have two different meanings.

Use the cgroup name for cpuset for lxc-ps

On my Ubuntu 13.10 system, lxc-ps was always giving empty output. The
output of /proc/$initpid/cgroup was

11:name=systemd:/user/1000.user/c3.session
10:hugetlb:/container
9:perf_event:/container
8:blkio:/container
7:freezer:/container
6:devices:/container
5:memory:/container
4:cpuacct:/container
3:cpu:/container
2:cpuset:/container

Using the cpuset line should be a safer option.

add lxc.haltsignal for soft shutdown

- use this in the busybox template since busybox's init expects
  to receive SIGUSR1 to halt

- fix lxc.stopsignal to be output by write_config so lxcapi_clone()
  and lxcapi_save_config() will output it

configure.ac: add docbook-to-man to dbparsers

Debian and Ubuntu uses docbook2x-man, but some other distr like suse
uses docbook-to-man. I think all of them should work on LXC.

fix it by checking the console.name before using it.
