There are a lots of strings being handled inside some LXC functions.
They can be moved to g_autofree to avoid declaring a return value to get
proper code cleanups. This commit is changing functions from
lxc_{controller,cgroup,fuse} only.

Ever since commit c5a00350 the libxl parser invokes the emulator
to probe which device model to use.

Commit b90c4b5f introduced a workaround that used a stable path
which was very likely to result in the answer matching the default.
However the test is still affected by the host state and the binary
gets invoked if present.

Mock the libxlDomainGetEmulatorType function to stop wasting CPU
cycles every time a 'make check' is run on a system with xen installed.

For example xlconfigtest gets faster by 90 %

The way that our file locking works is that we open() the file we
want to lock and then use fcntl(fd, F_SETLKW, ...) to lock it.
The problem is, we are doing all of these as root which doesn't
work if the file lives on root squashed NFS, because if it does
then the open() fails. The way to resolve this is to make this a
non fatal error and leave callers deal with this (i.e. disable
remembering) - implemented in the previous commit.

There are some cases where we want to remember the original owner
of a file but we fail to lock it for XATTR change (e.g. root
squashed NFS). If that is the case we error out and refuse to
start a domain. Well, we can do better if we disable remembering
for paths we haven't locked successfully.

So far, in the lock state we are storing only the file
descriptors of the files we've locked. Therefore, when unlocking
them and something does wrong the only thing we can report is FD
number, which is not user friendly at all. But if we store paths
among with FDs we can do better error reporting.
