Add syslog support

Signed-off-by: Baptiste Daroussin <bapt@gandi.net>

To activate it specify lxc.syslog = <afacility>
For now the available facilities are: daemon, local[0-7] others will be
rejected

syslog got only activated after the function that checks for inheritance
of fd is passed in order to make sure the syslog fd is not inherited
and prevent the creation of the fd is any log have been issued during
the checks (which would end up in an infinite loop)

conf: set pty_info to NULL after free

This fixes a double free corruption on container-requested
reboots when lxc_spawn() fails before receiving the ttys, as
lxc_fini() (part of __lxc_start()'s cleanup) calls
lxc_delete_tty().

attach: use setns instead of unshare

Revert "Merge pull request #1103 from brauner/2016-07-27/fix_android_…

This reverts commit 25796416, reversing
changes made to 813d7f14.

Contrary to what we suspected the android build errors were not caused by
missing wrong relative include paths. Rather, they were caused by autoconf.

lxc-checkpoint will fail because process createdy by lxc-attach has
incorrect cgroup ns. It needs to use "setns" instead of "unshare"
to set cgroup ns.

Both functions advertise that they return true when strncmp() == 0 and false
when strncmp() != 0 but so far they returned the exact opposite.
