  Changed paths:
    A config/tls.m4
    M configure.ac
    M src/lxc/lxclock.c
    M src/lxc/lxclock.h
    M src/lxc/utils.c

  Log Message:
  -----------
  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 at 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.
