Following a comment on the mailing-list, I made utmp.h return -1
when it's disabled, the problem with that is that it prevents the
container from starting completely, which isn't quite what I wanted.

This change makes the function succeed, the container will therefore
start but without utmp handler.

There's no good reason to call setup_mount_entries if we don't have any

call in setup_mount_entries requires the presence of /tmp which isn't the
case by default.

alphasort doesn't have the right signature on bionic which causes the build to
fail. This implements a new bionic_alphasort function when building on bionic
providing the right signature and a functional equivalent of glibc's alphasort.

This signature problem with alphasort was fixed in upstream bionic but hasn't
been released yet. This commit can therefore be reverted as soon as the
following commit hits the Android NDK: 40e467ec668b59be25491bd44bf348a884d6a68d

lxc-start -c makes the named file/device the container's console, but using
this with a regular file in order to get a log of the console output does
not work very well if you also want to login on the console. This change
implements an additional option (-L) to simply log the console's output to
a file.

Both options can be used separately or together. For example to get a usable
console and log: lxc-start -n name -c /dev/tty8 -L console.log

The console state is cleaned up more when lxc_delete_console is called, and
some of the clean up paths in lxc_create_console were fixed.

The lxc_priv and lxc_unpriv macros were modified to make use of gcc's local
label feature so they can be expanded more than once in the same function.
