lxccontainer: do_lxcapi_save_config() 
If liblxc is used multi-threaded do_lxcapi_save_config() could be called from
threads that fork() which to not risk ending up with invalid locking states we
should avoid using functions like fopen() that internally allocate memory and
use locking. Let's replace it with the async-signal safe combination of
open() + write().

confile: use mmap() to parse config file 
Sigh, this is going to be fun. Essentially, dynamic memory allocation through
malloc() and friends is unsafe when fork()ing in threads. The locking state
that glibc maintains internally might get messed up when the process that
fork()ed calls malloc or calls functions that malloc() internally. Functions
that internally malloc() include fopen(). One solution here is to use open() +
mmap() instead of fopen() + getline().
